President, The Independent Institute
Ladies and gentlemen, I want to welcome you to our program this evening, entitled States of Fear: Science or Politics? My name is David Theroux and Im the President of the Independent Institute. Were delighted to have you join with us this evening, and we hope that youll enjoy tonights program.
For those of you who are new to the Independent Institute, the Institute is a scholarly, nonpolitical, nonpartisan, public policy research institute. The Institute sponsors in-depth studies by major scholars on important issues, not unlike tonights. Results of this work are published as books and forms the basis for numerous conference and media projects.
Almost 20 years ago, we founded the Independent Institute to pursue research into what was the actual nature and consequences of government policy, without regard to prevailing popular or political biases, trends, or phobias. We wanted instead to create an organization that would support scholars exploring important areas that might otherwise be ignored, including questions normally considered out of the box, irreverent, and certainly controversial, but which were crucial to our understanding of how to get to real answers to lasting solutions. As a result, the Institute was founded to cut through the intellectual poverty, noise and spin of special interest-driven public policy in the U.S. and around the world.
In order to do so, we had to establish a new kind of research institute, one of a kind, frankly, in the public policy field, which is so dominated by highly partisan advocacy groups of every stripe. As a result, the Institute was started without the financial backing of any special interestindustry, labor, government or otherwise. We had, in fact, no angels at all.
But we had a deceptively simple ambition to pursue our work based solely on one and only one criterion. All of our studies had to be based on solid peer-reviewed scholarship and science, period. In effect, we became the first garage think tank, and today, we have over 140 research fellows at universities. So, we invite you to get to know us better. We hope youll enjoy getting beyond the stereotypes of left and right into the realm of innovative, bold ideas. We believe that such ideas are the key to a brighter future.
Tonights program, as you know, features Dr. Michael Crichton, the renowned best-selling author of such books as Jurassic Park, The Andromeda Strain, Prey, and his newest, State of Fear. Following Dr. Crichtons presentation, we will have a discussion with a distinguished panel of scientists.
Were also pleased that our program tonight is co-sponsored by the World Affairs Council of Northern California and made possible by the kind and generous assistance of members of our host committee, and the names of those you can find on the program that each of you has received. I also want to especially thank Fred Hamden, John Campbell, Nichelle Beardsley, and the entire staff of people at the Institute who have worked so hard in coordinating the many details that has made tonight possible.
But most of all, I want to thank another person who really made tonights program possible, and thats my son Paul Theroux. It was Paul who got me to read Michael Crichton in the first place, and he first alerted me to the fact that in Michaels book, State of Fear, Michael very kindly recommended one of our books called The Poverty of Reason by Oxford economist Wilfred Beckerman. It was this connection by Paul that directly led to our program this evening, and Im deeply grateful and I wanted to credit him for that.
Incidentally, I want to invite each of you to pick up a copy, if you dont already have one, of the quarterly journal of the Institute, which is called The Independent Review. There are complimentary copies outside in the lobby. And in your program, you will also see information about our next event, which is on December 13th. It will feature two scholars, one being Henry Miller, whos a senior fellow at the Hoover Institution at Stanford, and Bruce Ames, professor of biochemistry and molecular biology at the University of California.
Tonights program is of special significance to us at the Independent Institute because it deals directly with one of the most serious dilemmas I believe that were facing today. Throughout the history of man, thereve been theories and suppositions that people have had. In the program, we mention a couple of them, such as the geocentric or Ptolemaic theory of the universe that once believed that the Earth was at the center of the universe, of the solar system, the eugenics movement, which was essentially supported by virtually every person of any standing in the U.S. at one point.
More recently, once our best medical minds thought peptic ulcers were a lifestyle disease, the result of too much stress, too much spicy food or some combination thereof. And when Australian physician Barry Marshall suggested that perhaps ulcers might have a bacterial cause, his findings were utterly dismissed by colleagues as the most preposterous thing theyd ever heard, unquote. Sound familiar?
Yet, this years Nobel Prize in medicine to Dr. Marshall clearly illustrates that the history of science shows just because a scientific consensus on any subject does not mean that such consensus is correct or true, and errors in mainstream thinking often are discovered by investigators from outside orthodox circles.
Before we begin, a couple of quick program matters. After the presentation, we will have questions from the audience. In your programs youll find a card, and youre welcome to write your question on that. Please simply jot it down, and there will be ushers circulating in the aisles to pick them up. After the question period, we will adjourn, and Dr. Crichton has kindly offered to autograph copies of his book State of Fear, which will be done in the outer lobby.
Michael Crichton himself is widely regarded as the father of the techno-thriller. Hes the author of 21 books, some of which I just mentioned. His books have sold more than 150 million copies, translated into 36 languages, with 12 made into films. He is the recipient of an Emmy, a Peabody, a Writers Guild of America award for the TV series ER. Dr. Crichton is a graduate of Harvard Medical School and has been a visiting lecturer in anthropology at Cambridge University, Henry Russell Shaw Traveling Fellow, post-doctoral fellow at the Salk Institute for Biological Sciences, and visiting writer at MIT.
Michael has challenged and thrilled people worldwide with his insights and creativity, and his devotion to truth seeking regarding scientific matters is our topic this evening. So it gives me great pleasure to introduce Michael Crichton.
Thank you, David. That was very nice. I was quite impressed with myself.
Im going to try and sit tonight, if thats okay. Most people think Im too tall already. Im going to challenge you tonight to revise your thinking and to reconsider some fundamental assumptions, assumptions that are so deeply embedded in our consciousness that we dont even realize that theyre there.
This is a map by the artist Tom Friedman. You know, I have to tell you that my favorite example of making the wrong assumptions is a story about a man who goes on vacation and leaves his cat with his best friend. And hes on vacation and the friend calls him up and says, Listen. Ive got some bad news. The cat got up on the roof and we cant it down. We called the fire department. They came. The cat jumped to a tree. They went up the tree, but anyway, the cat fell, the cats dead.
They guy said, Oh, my God! How can you tell me in this way?
He said, Well, how should I have told you?
He said, Well, you have to prepare me. The first day, you should have called and said, listen, the cats on the roof and we cant get her down. Then the second day, you call and you say the fire departments here and the cats jumped to the tree, and the third day, you call me and you say the cat died, and by then, Im prepared.
The guy said, Oh, thats the way you want it? He said yes.
He continues his vacation. Gets a call a week later, and his friend says, Listen, your mothers on the roof and we cant get her down.
This is a map, and the assumptions that Im going to talk to you about today are not getting your mother down, but another kind of a map, a map that tells us how the world works. And particularly, I would like to try and direct our attention to the notion that most people make the assumption of linearity in a world that is largely non-linear. I hope that at the end of this talk, the meaning of that statement will be clear, but we wont be getting there in a linear fashion.
Some of you know that Ive written a book that many people find controversial, called State of Fear, and I want to tell you how I came to write it, because up until about five years ago, I had very conventional ideas about the environment and the environmental movement. This book really began in 1998, when I decided to write a novel about a global disaster. That was one of the first books Id written, and I thought, well, Im old now. Ill write another one.
And in the course of my preparation for this book, I rather casually reviewed what had happened at Chernobyl, because I regard Chernobyl as the largest manmade disaster that I knew about. What I discovered stunned me. Chernobyl was a tragic event, but nothing remotely close to the global catastrophe that I was imagining. About 50 people had died in Chernobyl, roughly the number of Americans that die every day in traffic accidents. I dont mean to be gruesome, but it was a setback for me. You cant write a novel about a global disaster in which only 50 people die.
I was undaunted. I began to research other kinds of disasters that might fulfill my novelistic requirements, and thats when I began to realize how big our planet really is and how resilient its systems ordinarily seem to be. Even though I wanted to create a fictional catastrophe of global proportions, I found it hard to come up with a credible example. I couldnt actually come up with anything that I would believe, so in the end, I set the book aside and wrote something else.
But the shock that I had experienced reverberated in me for a while, because what Id been led to believe about Chernobyl was not merely wrong. It was astonishingly wrong. Lets review that for a minute.
These are the low estimates of immediate Chernobyl deaths as a consequence of the actual incident, and you see here the UPI in 1986, at the time of the disaster, predicted that there would be 2,000 immediate deaths. The New York Post thought there would be 16,000. The Canadian Broadcasting Company in 91 thought there would be that many, and you see the BBC and The New York Times in 2002 predicting at the low end 15,000 deaths. Their estimates were 15,000 to 30,000 deaths.
Now, there was a UN commission in 2000 that suggested that the catastrophe was nowhere near that proportion, and as you can see, the next UN commission in 2005 doesnt really show up on the graph, because the total numbers are 56.
Now, to report that 15,000 to 30,000 people are dead when the actual number is 56 represents a very large error.
To get some idea of just how big, lets imagine that we lined all the victims up in a row. If 56 people are each represented by one foot of space, then thats probably the distance from me to about the second table here, something like that. Fifteen thousand people is three miles away. It seems difficult to make a mistake of that scale.
But of course, youre probably thinking, were talking about radiation. What about long-term consequences? Unfortunately for the media, their reports are even less accurate here. Here you see CNN in 1996 was predicting future Chernobyl-related illness and death in a large swath that would go from Sweden to the Baltic to the Black Sea. It estimated three and a half million. The BBC, much more conservatively, estimated 50,000. Agence Press thought half a million. The Ukrainian Victims Group in 2002 estimated 150,000. The UN commission in 2005 decided that there would be about 4,000. Thats the number of Americans who die of adverse drug reactions in this country every six weeks. Again, a huge error.
But most troubling of all, according to the UN report, was that the largest public health problem created by the accident was the damaging psychological impact due to a lack of accurate information.
This was manifesting asthey saidnegative self-assessments of health, belief in a shortened life expectancy, lack of initiative and dependency on assistance from the state. In other words, the greatest damage to the people of Chernobyl was caused by bad information. These people werent blighted by radiation so much as by terrifying, but false, information.
We ought to ponder for a minute exactly what that implies. We demand strict controls on radiation because its such a health hazard, but clearly Chernobyl suggests that false information can be a health hazard as damaging as radiation.
Im not saying that radiation is not a threat. Im also not saying that Chernobyl is not a genuinely serious event. But thousands of Ukrainians who didnt die were made invalids out of fear. They were told to be afraid. They were told they were going to die when they werent. They were told their children would be deformed when they werent. They were told they couldnt have children when they could. They were authoritatively promised a future of cancer, deformities, pain and decay. Its no wonder they responded as they did.
In fact, we really need to recognize that this kind of human response is very well documented. Authoritatively telling people they are going to die can in itself be fatal.
You may know that Australian aborigines fear something called pointing the bone. A shaman shakes a bone at a person, sings a song, and soon after, the person dies. This is a specific example of a phenomenon generally referred to as hex death. A person is cursed by an authority figure and subsequently dies. According to medical studies, the person generally dies of dehydration, implying that they just give up. But the progression is very erratic, and shock symptoms may play a part, suggesting adrenal effects of fright and hopelessness. Yet this deadly curse is nothing but information, and it can be undone with information.
A friend of mine was an intern at Bellevue Hospital in New York when a 28-year-old man from Aruba came in saying he was going to die because hed been cursed. He was admitted for a psychiatric evaluation and found to be normal, but his health steadily declined while he was in the hospital. My friend was able to rehydrate him, balance his electrolytes and give him nutrients, but nevertheless, the man worsened. He insisted that he was cursed and that nothing could be done to prevent his death.
My friend realized that this patient would, in fact, soon die. The situation was desperate. Finally, he told the patient that he, the doctor, was going to invoke his own powerful medicine to undo the curse, and his medicine was more powerful than any other. He then got together with the house staff, bought some head dresses and rattles, and danced around the patient in the middle of the night chanting what they hoped would be effective-sounding phrases. I think several of them were trying to remember their bar mitzvah.
The patient showed no reaction, but the next day, he began to improve. He went home a few days later, and I would say that my friend literally saved his life.
This suggests that Ukrainian invalids are not unique in their response, but the large numbers of what we might call information casualties represent a particularly egregious example of what can happen from false fears.
Once I looked at Chernobyl, I began to remember some other fears in my life that had also never come true, the population bomb, for one. Paul Ehrlich predicted mass starvation in the 1960s, 60 million Americans starving to death. That didnt happen. Other scientists warned of mass species extinctions by the year 2000. Ehrlich himself predicted that half of all species would become extinct by 2000. That didnt happen. The Club of Rome told us we would run out of raw materials ranging from oil to copper by the 1990s. That didnt happen either.
Its no surprise that predictions frequently dont come true. But such big ones, and so many! All my life, I worried about the decay of the environment, the tragic loss of species, the collapse of ecosystems. I worried a lot. Poisoned by pesticides, Alar on apples, falling sperm counts from endocrine disrupters, cancer from power lines, cancer from saccharine, cancer from cell phones, cancer from computer screens, cancer from food coloring, hair spray, electric razors, electric blankets, coffee, chlorinated water. It never seemed to end.
Only once, when on the same day I read that beer was a preservative of heart muscle and also a carcinogen, did I begin to realize the bind that I was in.
But Chernobyl started me on a new path. When I began to research these old fears to find out what had been said in the past, I discovered several important things. The first is that theres nothing more sobering than a 30-year-old newspaper. You cant figure out what the headlines mean, you dont know who the people are. Theodore Green, John Sparkman, George Reedy, Jack Watson. Who were they? You thumb through page after page of vanished concerns, issues that apparently were important at the time and now dont matter at all. Its amazing how many pressing concerns are literally of the moment. They wont matter in six months, and certainly not in six years, and if they wont matter then, are they really worth our attention now?
But as David Brinkley once said, the one function TV news performs very well is that when there is no news, we give it to you with the same emphasis as if there were.
We miss him.
The second thing I discovered was that attempts to provoke fear tended to employ a certain kind of stereotypic and very intense language. For example, heres a quote on climate:
Familiar language, isnt it? But this is not actually about global warming. Its about global cooling, fear of a new ice age. Is anybody here worried about an ice age? Is anybody upset that we didnt act now back then, to stockpile food and all the other things we were warned that we had to do?
Heres a quote from a famous computer study in the 1970s that predicted a dire future for mankind unless we act now. And just notice the language here:
Very heavy stuff.
Heres Paul Ehrlich talking about what he thinks were going to have to do. Hes talking about population. As you know, he favored voluntary controls, but if voluntary controls didnt work, he favored coercive controls. He said,
Ah, heres the UN. This is about Y2K:
Now, nearly everybodys forgotten about Y2K, so let me remind you of what was predicted six years ago. Heres one author who said he was assuming at least a 12-month disruption of basic goods and services including no electrical power, no clean water, no telecommunications, shortages of food, gas, clothing and retail goods, bank failures, inaccessibility of funds, stock market crash, dramatic drop in real estate prices. Were still waiting for that.
Economic depression, unemployment, civil unrest, including protests, riots and general lawlessness. This is actually one of the milder predictions.
Heres another one. Heres another prediction that simply pointed to a meltdown of civilization as we know it. Cant get any stronger than that.
But what actually happened? Essentially nothing. And the UN was pleased:
Now, theres only one problem. The governments didnt really have anything to do with it. Now you may think, well, wait a minute. Y2K was a real problem, and the concerns, even if they were exaggerated, nevertheless mobilized people and led them to success. This is a common but entirely erroneous view.
Its easily demonstrated here. The United States government on Y2K spent $6 billion. Citibank alone spend nearly $1 billion, and total U.S. expenditures were in the region of $100 billion, which means the government spent six percent of the total. Globally, as you can see, there were $200 billion in expenditures, so you see something like this.
So, heres the United States government, and we are asked to imagine that it is responsible for saving us from this crisis. Would Citibank have spent the money to fix its Y2K problem without government urging? Of course, because not to do so would have put them out of business, and the same with other banks and businesses around the world. Yet, government takes credit.
To encourage what is happening anyway is a common strategy in many areas of advocacy. For example, it now seems clear that despite the warnings of Paul Ehrlich and others, we are not going to have a population explosion of 14 billion people and accompanying mass starvation.
How did we avoid this explosion? Because, the head of Planned Parenthood once explained to me, everybody in the world listened to Ehrlich and got busy stopping population growth. I could see in my mind Yemeni tribesmen, you know, finding a copy of the book.
But the more significant point is that I was really astonished that she was so ill-informed about her subject area, because Ehrlich may be a celebrity in the West, but his advocacy had little to do with solving the problem of population, because that problem was already being solved by itself at the time he wrote the book.
Here is a graph from the World Bank. Its not very easy to understand, but its the World Bank.
If we look here at where Ehrlichs book appeared, you see that theits hard for me to follow. Anyway, the birth rate in developed countries was falling for about 100 years at that point, and in the developing nations, it had been falling for close to a decade. Ehrlich was thus urging people to do what they had already been doing for some time, and its not clear to me whether he knew that or not. But certainly when he said, The battle to feed all of humanity is over; at this late date, nothing can prevent a substantial increase in the world death rate, hes simply wrong. You can see the death rate here for the developed countries and the death rate here for the developing countries, and as you can see, it never went up.
Ehrlichs message, crying out in desperation to urge whats already happening, is not unique. We have a contemporary example of the call by politicians and activists to end our dependence on fossil fuels and move to a carbon-neutral lifestyle. Their call to action is, however, a little bit late.
According to Jesse Ausubel of the Rockefeller Institute, the industrialized nations have been decarbonizing their energy sources for 150 years, meaning that we are moving away from carbon toward hydrogen. In other words, the ratio of carbon to hydrogen decreases as you go from wood and hay, which is one to one, to coal, to oil, and finally to natural gas, where its one to four.
Heres an illustration from one of Ausubels articles. The blue atoms are hydrogen and the dirty brown ones are carbon.
And you can see as we go from coal to oil to gas, natural gas, if theres still any for sale, we are increasing the proportion of hydrogen to carbon. Ausubel expects this trend will continue through this century as we move toward what he imagines as a pure hydrogen energy system, without the assistance of lawyers and activists. Obviously, if a trend has been continuously operating since the days of Lincoln and Queen Victoria, it probably does not need the assistance of organizations like the Sierra Club and the NRDC, which are showing up about a hundred years too late.
Ausubels ideas are controversial to some, but not to websites like Sustainability Now. And this is again showing you the ratio of hydrogen and pure, clean blue to carbon and other various sources.
All right. So in summary, when I went back to look at old fears, the first thing I found was that newspapers were largely empty. The second thing I found was that the language was uniformly and excessively frightening. And the third thing I found was that a lot of advocacy was encouraging what was happening anyway.
But I learned some other things too. One interesting feature is the tendency toward reversals. A benefit becomes a hazard and then becomes a benefit again. Butter is good, then its bad, and then its good. Saccharine is good, then its bad, then its good again.
But this is also true for some much larger scares, like cancer and power lines, which hit the media in 1989. Before 1989, there were books like this, which saw magnetic fields as necessary for life.
Then in 1989, Paul Broders articles in the New Yorker magazine, a source of erroneous scientific information for many decades. And his strong position brought people that agreed with him. Heres a consumers guide to the issues of electromagnetic fields and how to protect ourselves.
Then a funny thing happened. After about a decade, magnetic fields were rehabilitated, and you can chart that progression here. This is 1997, 1998, 2000, 2001. Now its getting sexy. And finally, its kind of New Age-y.
Now, the end stage of this process is something like this. Here is an ad that tells you that you need to get this magnetism that exists in the earth. But since nature is drastically depleted, this environmental supplement is incredibly important, and they will sell you magnets to increase your supply of it.
Now, we see we have completed the circle from fear to selling point, from magnetic fields that are too powerful for health to fields that are too weak for health.
Of course, rather than buying these magnets, you could just stand alongside a power line, or sit with your back to a TV set. Snuggle up to a kitchen appliance. Theres lots of ways to increase your exposure to healthful magnetic fields.
Im reviewing these past fears not to make fun of them, but because I think this back and forth quality, the fears that suddenly rise and subside, are symptomatic of a deeper problem with modern environmental thinking, a problem that we have to face. But meanwhile, the fears do continue to rise and fall. Lets look at some graphs of past fears.
To get a rough idea of the visibility of fears, I did word search on Nexus for two newspapers, The Washington Post and The New York Times. These provide very rough measures, but theyll show you a trend. Heres the graph for power lines and cancer.
As you can see, not much interest. A peak following Broders book. A decline here, which I think is people sensibly saying, Wait a minute, and then the thing has its own momentum and slowly declines as the whole thesis unravels. Cost of this thing is about $25 billion start to finish.
A similar sort of pattern we have for the population explosion. This may be a little hard to see, but we can run a five-year average ofthis is articles that appeared in The New York Times, and you can see finally, we are in serious decline. If this were a stock, sell it.
And finally, here is a much sharper peak for Y2K.
As you see, a sudden spike. Two articles a day in The Washington Post in 1999, and then it collapsed to almost nothing. This later drift upward appears to have two causes. First, theres a band called Y2K, and second, theres a steady trickle of self-congratulatory articles in which people say its wonderful that we stopped the dreaded crisis in time.
But I only want to emphasize the patternnew fears rising and falling to be replaced by others that rise and fall. As Mark Twain said, Ive seen a heap of trouble in my life, and most of it never came to pass. But I suggested that this pattern is, in itself, indicative of a problem in how we approach the environment, and Id like to talk about that now.
Environmental disputes frequently revolve around conflicts of land use triggered by fears. The spotted owl is endangered, and that means logging in the Northwest must stop. People are put out of work. Communities suffer. It may be in 10 or 30 years that we discover that logging was not a danger to the spotted owl, or it may be that we discovered it was.
But my point is that the drama surrounding these disputesangry marches, press coverage, tree hugging, bulldozersserves to obscure the deeper problem. The deeper problem is, we dont know how to manage the environment even when theres no conflict at all.
As a good example of why, lets take a case history of our management of the environment, Yellowstone National Park.
This is the welcome sign. Long recognized as a scene of great natural beauty, in 1872, Ulysses Grant set aside Yellowstone as the first formal nature preserve in the world. More than two million acres, larger than Delaware and Rhode Island combined. John Muir was very pleased when he visited in 1885, noting that under the care of the Department of the Interior, Yellowstone was protected from, quote, the blind, ruthless destruction that is going on in adjoining regions.
Theodore Roosevelt was also pleased in 1903, when as President, he went to Yellowstone for a dedication ceremony. Here he is. This was his third visit. Roosevelt saw a thousand antelope, plentiful cougar, mountain sheep, deer, coyote and many thousands of elk. He wrote at that time, Our people should see to it that this rich heritage is preserved for their children and their childrens children forever, with its majestic beauty all unmarred.
But in fact, Yellowstone was not preserved. On the contrary, it was altered beyond repair in a matter of years. By 1934, the Park Service acknowledged that whitetail deer, cougar, lynx, wolf, and possibly wolverine and fisher are gone from the Yellowstone.
What they didnt say was that the Park Service was solely responsible for the disappearances. Park rangers had been shooting the animals for decades, even though that was illegal since the Lacey Act of 1894. But they thought they knew best. They thought their environmental concerns trumped any mere law.
What actually happened at Yellowstone is a cascade of ego and error, but to understand it, we have to go back to the 1890s. Back then, it was believed that elk were becoming extinct, so these animals were fed and encouraged. Over the next few years, the number of elk in the park exploded. Here you can see them feeding them hand to hand.
Roosevelt had seen a few thousand animals on his visit, and hed noticed that the elk were more numerous than in his previous visit. Nine years later, in 1912, there were 30,000 elk in Yellowstone. By 1914, there were 35,000.
Things were going very well. Rainbow trout had also been introduced, and although they crowded out the native cutthroats, nobody really worried. Fishing was great. Bears were increasing in numbers, and moose and bison as well.
By 1915, Roosevelt realized the elk had become a problem, and he urged scientific management, which meant culling. His advice was ignored. Instead, the Park Service did everything they could to increase the number of elk. The results were predictable. Antelope and deer began to decline. Overgrazing changed the flora. Aspen and willows were being eaten at a furious rate and did not regenerate. Large animals and small began to disappear from the park.
In an effort to stem the loss, the park rangers began to kill predators, which they did without public knowledge. They eliminated the wolf and the cougar, and they were well on their way to getting rid of the coyote. Then a national scandal broke out. New studies showed that it wasnt predators that were killing the other animals. It was overgrazing from too many elk. The management policy of killing predators therefore had only made things worse.
Actually, the elk had so decimated the aspen that now, where formerly they were plentiful, now theyre quite rare. Without the aspen, the beaver, which use these trees to make dams, began to disappear from the park. Beaver were essential to the water management of Yellowstone, and without dams, the meadows dried hard in summer and still more animals vanished.
The situation worsened further. It became increasingly inconvenient that all the predators had been killed off by 1930, so in the 1960s, there was a sigh of relief when new sightings by rangers suggested that wolves were returning. Of course, there were rumors all during that time, persistent rumors that the rangers were trucking them in. But in any case, the wolves vanished soon afterward. They needed to eat beaver and other small rodents, and the beaver had gone.
Pretty soon, the Park Service initiated a PR campaign to prove that excessive elk were not responsible for the problems in the park, even though they were. The campaign went on for about a decade, during which time the bighorn sheep virtually disappeared.
Now, were in the 1970s, and bears were recognized as a growing problem. They used to be considered fun-loving creatures, and their close association with human beings was encouraged in the park. Herere people coming to watch bear feedings. Theres a show at a certain hour of the day. And heres one of my favorites. Setting the table for bears at Lake Camp in Yellowstone Park. You see theyre very well behaved.
But that didnt actually continuethe good behavior, I mean. There were more bears, and certainly there were many more lawyers, and thus the much-increased threat of litigation, so the rangers moved the grizzlies out. The grizzlies promptly became endangered. Their formerly growing numbers shrank. The Park Service refused to let scientists study them, but once they were declared endangered, the scientists could go back in again.
And by now, were about ready to reap the rewards of our 40-year policy of fire suppression, Smokey the Bear and all that. The Indians used to burn forests regularly, and lightning causes natural fires every year. But when these are suppressed, branches fall from the trees to the ground and accumulate over the years to make a dense groundcover such that when theres a fire, it is a very low, very hot fire that sterilizes the soil. In 1988, Yellowstone burned, and all 1.2 million acres were scorched, and 800,000 acres, one third of the park, burned.
Then having killed the wolves, having tried to sneak them back in, they officially brought the wolves back. And now the local ranchers screamed. The newer reports suggested the wolves seemed to be eating enough of the elk that slowly, the ecology of the park was being restored. Or so it is claimed. Its been claimed before. And on and on.
As the story unfolds, it becomes increasingly impossible to overlook the cold truth that when it comes to managing 2.2 million acres of wilderness, nobody since the Indians has the faintest idea how to do it. And nobody asked the Indians, because the Indians managed the land very aggressively, very intrusively. The Indians started fires regularly. They burned trees and grasses. They hunted the large animals, elk and moose, to the edge of extinction. White men refused to do that, and made things worse.
To solve that embarrassment, everybody pretended that the Indians had never altered the landscape. These pioneer ecologists, as Stuart Udall once called them, did not manipulate the land. But now, in recent years, the wisdom of Indian land management policies is increasingly difficult to cover up.
All right, if were going to do better in this new century, what must we do differently? What is the story of Yellowstone really telling us? I would argue that, in a phrase, we must embrace complexity theory. We must understand complex systems. We live in a world of complex systems. The environment is a complex system. The government is a complex system. Financial markets are complex systems. The human mind is a complex system. Most minds anyway.
By a complex system, I mean one in which the elements of the system interact among themselves such that any modification we make to the system will produce results that we cant predict in advance.
In addition, a complex system is sensitive to initial conditions. You can get one result from it on one day, but the identical interaction the next day will yield a different result. We cannot know with certainty how the system will respond. Third, when we do something to a complex system, we may get downstream consequences that emerge weeks or even years later. We have to be watchful for delayed and untoward consequences.
The science that underlies our understanding of complex systems is now 30 years old. A third of a century is plenty of time for this knowledge to filter down to everyday consciousness, but except for slogans like the butterfly flapping its wings and causing a hurricane halfway around the world, not much has really penetrated general human thinking.
On the other hand, complexity theory has raced through the financial world. It has been briskly incorporated into medicine. But organizations that care for the environment dont seem to notice that their administrations are often deleterious, in many cases. Lawmakers dont seem to notice when their laws have unexpected consequences. Or maybe they notice, but they dont want to notice. Governors and mayors and managers may manage their complex systems well or badly, but if they manage well, it is usually because they have an instinctive understanding of how to deal with complex systems. Other managers fail. Why?
Our human predisposition is to treat all systems as linear when theyre not. A linear system is a rocket flying to Mars or a cannonball fired from a cannon. Its behavior is quite easily described mathematically. A complex system is water flowing over rocks, or air flowing over a birds wing. The mathematics is complicated, and in fact, no understanding of these systems was possible until the widespread availability of computers.
One complex system that most people have dealt with is a child. If so, youve probably experienced that when you give the child an instruction, you cant be certain what the response will be, especially if the child is a teenager. And similarly, you cant be sure that an identical interaction on another day wont have a spectacularly different outcome.
So, if you have a teenager or if you invest in the stock market, you know that a complex system cannot be controlled. It can only be managed. Because its behavior cannot be predicted, it can only be observed and responded to. An important feature of complex systems is that we dont know how they work. We dont understand them. We just interact with them. Whenever we think we understand them, we learn we dont.
What then happened in Yellowstone? I would argue people thought they understood the system, and they were wrong.
Lets look back. Heres the 1970s, the Club of Rome yellowing with age. And they had a chart back then to explain what regulates fertility. Its surprisingly simple. The problem is that some years later, most professional demographers no longer believe that they can predict precisely the future growth rate, size, composition and special distribution of populations. This graph at the top is silly.
And there are many others. Heres one of my favorites. This gets population and industrial capital all on one single page. Its really fantastic.
OK. Highly simplified thinking, and it goes on to this day.
Here is a modern chart from a sustainability website. It shows the relationships of pretty much everything, lithosphere, biosphere, market, community, customers. Who makes a chart like this?
Im asking a serious question. Who thinks the world operates in this way? Because look.
It does not explain the world. One side is not an explanation of the other side. In fact, the chart showing everything is absurdly simple.
Here, for example, is a more complex diagram that represents the nerves of the stomach of the lobster. And look. This kind of simplification doesnt even explain man-made complex systems.
Heres a financial market, and we all know that if you were to make one single change, say, increase the price of crude oil or charge a White House aide with a felony, you could not be sure how the financial system would react. Nobody knows in advance. People make their businesses out of trying to figure it out, but nobody knows except for inside traders. And thats the same for financial systems all around the world.
Heres an article from The New York Times, which, suggests that we cant even know the simplest things about our financial status. Is the nations productivity going up or down? Nobody knows.
If you cant even understand the basic aspects of man-made systems, what makes anybody think that we can understand natural environments that are thousands of times more complicated?
This is a storm hundreds of miles across, and we have, on the nightly news, people who will tell us what causes them, how they operate, and its really simple answers. Its an extraordinary thingwhich actually, we hadnt really been able to see in this way until we had satellites, is translated into such simple forms of thought. Its nonsense to think that you can know its behavior and its causes.
Similarly, at the microscopic level. Heres hemoglobin, a single molecule that weve studied for decades and are only beginning to really understand. As you see, hemoglobin is far more complicated than the original drawing that I showed you, which is a drawing of everything. A single molecule and a single cell is more complicated than that drawing of the entire world.
The heart that pumps these red cells is driven by an electrical stimulus that spreads across the heart muscle in a very complex way, a way that is now understood with the help of complexity theory. This is a conventional image, and here is a video image of conduction from Duke University five years ago, showing this in terms of how the conduction impulse spreads. And when you see images like this, you realize we are very far from the notion that how you proceed is just shoot a few wolves or shoot all the wolves. The natural world is vastly more difficult.
But this kind of understanding of natural processes, the kind of understanding that you get from complex systems, is precisely what has been missing from environmental thought. Thirty years later, I argue, its time to catch up. Stop worrying about decarbonization, which is taking care of itself, and start worrying about Yellowstone, which isnt.
OK. So what happened at Yellowstone? I would say somebody really believed that the world operated like this, and they acted on that belief. Kill the wolves, save the elk. Move the grizzlies, avoid the lawyers. And on and on. Its this kind of thinking that has to go, but we havent learned that lesson.
Here is a more recent story, which suggests that were going to kill bard owls in order to save spotted owls. Here on Santa Cruz Island, were going to kill the wild pigs, but actually its a little more complicated because therere eagles on the island. First we have to kill all the eagles, then we have to kill the wild pigs in order to save the foxes. Heres a notion that bringing the wolves back has actually reshaped Yellowstone and made everything wonderful again.
My argument is we can only have these simple ideas if we dont really understand what a complex system is. Were like the blonde who returned the scarf because it was too tight.
Im sorry. I have a daughter whos blonde and I have a wife whos blonde.
I have to tell you the story about the lawyer who got on the airplane and found himself, to his delight, seated next to an incredibly beautiful blonde who was turning away to go to sleep. He didnt want her to do that, so he said, Lets play a game. Ill ask you a question, and if you can answer it, Ill pay you $5, and if you cant, you pay me $5. And then you ask me a question, and the same.
She said no and turned away to go to sleep. He said, OK, wait. Ill ask you a question, and if you cant answer it, you pay me $5, and you ask me a question, and if I cant answer it, Ill pay you $500.
She sat up very alert. So he said, Ill go first. His first question was, what is the capital of Alabama? The blonde reached in her purse, gave him $5. He said, OK, its your turn.
She said, What goes up the hill on three legs and down the hill on four? He said, Uh? He got out his laptop. He Googled it. He did everything that he could, and he finally had to realize that he couldnt answer it. He gave her $500. She put it in her pocket.
He said, Whats the answer? She gave him $5.
Fortunately, we can learn to manage complex systems. There are people who have studied how to do it and know how to do it. But it does take humility, and with that, something very important, the ability to admit that were wrong and to change course.
If you manage a complex system, you will frequently, if not always, be wrong. You have to backtrack. You have to acknowledge error. You probably learned that with your children, or if you dont have children, with your bosses.
And one other thing. We have to not be afraid. Fear may produce a television audience, it may generate cash for an advocacy group, but fear paralyzes us. It freezes us. And we really need to put that behind us as we move into a new era of managing complexity, because, look.
Heres the Independent. The future of the Earth. Is this the end of the world? Earthquakes, hurricanes, floods. What is happening to our planet?
Is this the end of the world? No. We live on an active planet. Earthquakes are continuous, a million-and-a-half a year, or three every minute. A Richter 5 every six hours, a major quake every three weeks. Theres a quake the size of Pakistan every eight months. Look at Kobe, Japan. Despite building codes, the buildings just toppled. Very good building codes.
At any moment on our planet, there are 11 lightning strikes every second. There are 1,500 electrical storms on the planet at any moment. A tornado touches down every six hours. A tidal wave crosses the Pacific every three months. There are 90 hurricanes a year, one every four days. Its constant.
Is this the end of the world? No. This is the world. And I think its time we knew it. Thank you very much.
President, The Independent Institute
Thank you very much, Michael.
Before we turn directly to our panel of scientists, Im pleased to introduce a member of our host committee, if youd come up please. Dr. Bruce Ames is professor of biochemistry and molecular biology at the University of California, Berkeley. Professor Ames has receive the National Medal of Science from the National Science Foundation, the Tyler Prize, which is the highest award for environmental achievement, the Golden Medal award of the American Institute of Chemists, and the Japan Prize, among others. He has served on the National Cancer Institute board of directors, and he is a member of the National Academy of Sciences and the Royal Swedish Academy of Sciences. And Bruce very kindly has offered to make a few brief comments.
Professor, Biochemistry and Molecular Biology, University of California, Berkeley
I was asked to say a few things about my interaction with the environmental movement, which hasnt been completely happy, but Ill talk about it anyway.
So my passion is preventing disease, and for many years, I was interested in preventing cancer. If you asked all the worlds leading epidemiologists whove studied the subject, theyd come up with about the same list. Smoking is about a third of cancer, bad diets are another third of cancer, chronic infections, mostly in poor countries, hepatitis and schistosomiasis, all sorts of things like that. Helicobacter in your stomach, as we heard, about 20 percent. Hormones cause a lot of cell division and all of that, responsible for breast cancer, eudiometrical cancer. Occupation, a few percent.
And pollution, the numbers vary. Its all a guess, but it isnt much, and this less than one is my own estimate, and mostly heavy air pollution. But this is where were spending all the money by orders of magnitude. So somethings wrong if were putting our money on minor hypothetical risks and the major risks are not attended to.
Next slide. So, while we heard about the big cancer epidemic, there really isnt any cancer epidemic, other than due to smoking. If you look at cancer attributed to smoking, its going up, but if you look at cancer not attributed to smoking, its been going down. In fact, its been going down for a long time. So, there isnt a cancer epidemic other than that due to smoking, this 30-year delay after people smoke. Next.
And every week theres a scare story in the newspaper. It says, This new study says yes, but over 120 previous studies say no. Did you hear that folks? The answer is yes. And I think the reason is that it sells newspapers, so people are interested in poisoned apples. Theyre not interested in non-poisoned apples. Next slide.
So what about carcinogens?
Towards the end of the 1800s, when the chemical industrys going, we learn that some workers were wading around in beta-Naphthylamine and putting their hands in it and breathing it in, got bladder cancer. In fact, a high percentage of all the workers doing that got bladder cancer. So people realized chemicals can cause cancer, and so then, we didnt want our workers to be guinea pigs so we started testing these chemical in rats.
And we made a number of assumptions. One, well, since workers got cancer from these synthetic chemicals, its synthetic chemicals causing all the cancer, and two, well test it on rats and mice which are relatively cheap, and well feed them the maximum tolerated dose every day in a lifetime and see if they get cancer. And the reason for that is its expensive and the statistics in small numbers of animals, a third of the animals get cancer anyway just from living.
And then we said, well, we can go from this huge dose down to some low dose. And all these assumptions are turning out to be wrong. Next slide.
So Lois Gold, whos here, and I, some years ago, set up the Carcinogenic Potency Database. We took every animal cancer test that had ever been done in the world and put all the results in a computer and calculated potency of the carcinogen and other things, and some interesting numbers came out of that.
One is, about 60 percent of all the chemicals ever tested came out positive. Whats going on? Natural chemicals everybody thought were benign. Natures been around all the time, but you get exactly the same rate in natural chemicals as in synthetic chemicals.
And then you start looking at the natural pesticides in plants. Every plant makes a hundred toxic chemicals to kill off the predators. All of plant evolution is chemical warfare because they cant run away. They dont have immune systems. How do plants defend themselves? Toxic chemicals. So every time you eat a broccoli, youre getting a hundred toxic chemicals.
So when you test those, half of them come out as carcinogens just the way pesticides do. Mold toxins, natural chemicals in roasted coffeesorry about that commercial pesticides, mutagens. Non-mutagens. Anyway, I wont go any more into that. Next slide.
So Rachel Carson back in the 60s wrote this wonderfully written book, but I reread it recently, and it really made me ill because Rachel Carson wrote: For the first time in the history of the world, every human being is now subject to contact with dangerous chemicals from the moment of conception until death. But Rachel Carson was made of chemicals. Everythings made of chemicals. No toxicologist thinks much of a statement like that. Next slide.
And Rachel Carson, if five people did an experiment and one found it did something bad, she quotes the one and she doesnt quote the four other who found it didnt do anything bad. So, it wasnt really very scholarly, and I think it got people off on the wrong track.
So this is cabbage. These are some of the hundred toxic chemicals in cabbage. When you test those, they come out as carcinogen, just the way everything you test, half of them come out as a carcinogen. Next slide.
And so, we did some numbers and we calculated that were eating 100 chemicals in the part-per-billion range from little traces of pesticide residue. Really very tiny levels. A part per billion is one person in all of China, and unless its Mao, you just dont want to worry about it.
And natural pesticides, youre eating 1,500 milligrams a day, not .05 milligrams, so we calculated 99.99 percent of the pesticides, youre eating these natural chemicals in plants. Dont you think somebody would want to test those if they were doing animal cancer? No. But a few people around the world managed to test a few, and again, the same hit rate. Next slide.
This shows the carcinogenicity status of natural pesticide tested in rodents from our database that Dr. Gold runs. These were carcinogens or carcinogens in about half, so there are carcinogens in allspice, anise, apple, apricot, banana, basil, beer, broccoli, brussel sprouts, and then tomatoes, turmeric and turnip and everything in between. So, you cant go eat anything in the supermarket that doesnt have carcinogen in it becauserodent carcinogenbecause half of everything is coming out positive. Next slide.
So this shows coffee. Again, sorry about that, but there are a thousand chemicals that have been described in a cup of roasted coffee. And these are the carcinogens, these are non-carcinogens. There are still a thousand chemicals left to test.
So, if youre working for EPA, you gettheyre drinking their cups of coffee in the morning, but you get more carcinogens in one cup of coffee than pesticide residues you get in a year. So, somethings funny. Next slide.
Well, if its natural, we can ignore it. But thats not true. We know natures full of nasty things. So, some British toxicologist put this, the aims and achievements of toxicology illusion prevent human disease from chemical. The reality provide living for contract laboratories, civil service, lawyers, statisticians, consultants and conference organizers
Professor, Biochemistry and Molecular Biology, University of California, Berkeley
And the achievementsis public reassured that chemicals are properly tested for carcinogenic activity? And the reality is public worried to death for indifference by politicians and sensational press statement. Next slide.
So this says, Relax. Ive come for your toaster. And the point of that is, if you scare people about a thousand minor hypothetical risks, youre lost, because nobody knows whats important anymore.
And there are really important things out there. Were eating a horrible diet. Were getting fat. Were not getting our vitamins. And all this really matters. Being obese is linked to 40 different diseases, cancer, and all sorts of other things. And you dont get your iron or zinc, you batter up your DNA. Its like getting irradiated if you dont get your folic acid. And the poor are eating horrible diets, so I think theyre destroying their brains in addition to all their biochemistry.
So there are things to worry about, but the governments putting all its resources in the wrong place. Now, whether thats politicization of science or just misguided enthusiasm or what, I dont know. But you dont want to turn all this into a religion, and thats sort of what its become.

Id like to now turn to our panel of scientists. The first Im very pleased to introduce is Dr. Sallie Baliunas. Sallie is a staff astrophysicist at Harvards Smithsonian Observatory. She is former deputy director and director of science programs at Mount Wilson Observatory. She is a recipient of the Newton Lacy Pierce Prize and the Bok Prize, and she received her PhD in astrophysics from Harvard University.

This is a brief lesson in history about fear and ignorance of extreme weather 500 years ago. Now, as impossible as it is to comprehend events in the 20th century without understanding totalitarianism, it is likewise impossible to understand Europes 16th century without recognizing the role of superstition. Magic, witchcraft, sorcery and superstition pervaded every scale of culture from the smallest corner to the cosmic.
Now, an equable climate had pertained in Europe about a thousand years ago, and by the 14th century, that had deteriorated into a long period called the Little Ice Age. The Little Ice Age saw harsh winters, severe storms, and also extreme variability. That means you could see mild winters and then very severe winters, summer heat waves, droughts, sea storms and floods. The Little Ice Age persisted about 500 years, abating only in the 19th century in some places.
Now the most severe period of that 500-year period of the Little Ice Age occurred in Europe between 1550 and 1700. That was also probably the harshest period of weather in the last thousand years, if not longer. Now the severe conditions and climate brought about crop failure, starvation, disease, death and social unrest. But it was already occurring in a period of great upheaval, as the Reformation, the counter-Reformation and warfare battered Europe.
Now how unusual was this very intense period of the Little Ice Age? On the afternoon of August 3, 1562, a thunderstorm struck central Europe across a front several hundred kilometers long. After raging for several hours, the storm unleashed a terrific hail that continued until midnight. It destroyed crops. It destroyed vineyards, birds and unprotected horses and cows.
Diarists then noted something that we hear today. They said for a hundred years, such a storm had not been seen. The storm was deemed so unusual in this period of superstition that it had to be unnatural. It had to be supernatural. Thus, superstition and witchcraft bred a precautionary response. Eradicate those responsible for the storm and this period of new storminess.
Now, it was well known that people could cook weather with the help of Satan, so thus did extreme conditions of the severest part of the Little Ice Age contribute to Europes most horrific period of mass executions and witch trials. This was completely legal, and it was undertaken, administered, by highly educated upper social strata. These were institutionally legalized executions for sorcery. There are many reasons for these trials, but some of them are related to weather cooking, that is, working with Satan to produce these severe storms. The estimates now are about 50,000 executions across Europe, and no country was spared of this.
There were skeptics who stood up, but they were often accused of or threatened to be accused of sorcery to squash any debate. So legal philosopher Jean Bodin in 1580 noted that witchcraft was the most terrible problem facing humankind. Again, a very modern note.
Bodin championed the international attack against skeptics like Johann Beyer. Now, Johann Beyer was a physician, and Beyer argued that the accused sorcerers seemed to be suffering from what he thought were medical conditions we would modernly term mood disorders. He also thought it was theologically impossible for Satan to work through such people to do his work. Beyer then declared that confessions that had to be extracted by torture because there was very little direct proof of witchcraftwell, these confessions were extracted by torture, and he found this torture immoral.
So the response? Jean Bodin decided to accuse him of witchcraft, so any feeble notes of humane skepticism had to be wrenched out of society. Jean Bodin wrote in response to Beyers humane skepticism, Any country which tolerates these skeptics will be struck by plagues, famines and wars. Now since it was known that witches caused weather and this unusual weather raged, so did the tortures and executions.
How severe did it get? Well, on May 24, 1626, a hailstorm struck central Germany and dropped one meter of hail. Two days later, an arctic front descended onto central Europe and bit hard. Rivers froze, grape vines exploded, the rye and barley crops were destroyed. Tree leaves were blackened and fell to the ground and denuded the trees, and people thought it was Y2K.
Sallie L. Baliunas
Astrophysicist, Harvard Smithsonian Center for Astrophysics
Now, the lord mayor of Zeil in Franconia, Johann Langens wrote, Everything was destroyed by the frost, which had never happened in peoples memory. Which was true. Probably a frost that severe hadnt occurred in 500 years, but since it was so unusual, it had to be unnatural, given that centurys reigning paradigms. Whereupon, continues Johann Langens, whereupon an intensive pleading and begging started among the rabble. Why did the authorities tolerate these sorcerers and witches? The sorcerers and witches must be punished.
So punish them, the authorities did. In this area of central Germany in 1626 alone, Bamberg executed 600, Wurtzburg 900, in electorate Mantz, 900 more were executed, and Westphalia, 2,000. Thats just the result of the 1626 frost, and those are directly related to weather cooking.
Science is the only successful means we know of to explain nature, and growth of wealth is the only successful means we have to afford prediction, preparation for and survivalin order to survive extreme weather, which has always happened and always will. But science needs special societal protection, and without that protection, science will just be dialed out and in its place will be substituted the myths that humans love to create, myths like weather cooking.
I told you we had an interesting program tonight.
Our next panelist is Dr. William Gray. Bill is professor of atmospheric science at Colorado State University. Hes head of the Tropical Meteorology Project at Colorado State and a fellow of the American Meteorological Society. Bill.

Professor, Atmospheric Science, Colorado State University
Thank you, David. When I was growing up, I had two heroes, the great pitchers Walter Johnson and Bob Feller. The only thing I wanted in life was to make the major leagues, but I got a knee injury and all that ended. Now, I havent had any heroes since until last year, and I got a new hero. Its Michael Crichton.
Not that I knew much about Michael before I read Aliens Create Global Warming and the last, I think, 35 pages of his non-fiction material of his last novel, but those two items really moved me greatly, and I found, gee, heres a kindred spirit. Ive been thinking about this stuff for a long, long time, and Im older than Michael.
Anyways, I have been amazed at how hes stood against the tide of this human-induced global warming. Ive been around over 50 years working. Ive been all in the forecasting, doing research on data, flying into storms, doing all this stuff for 50 years. And I was appalled when the nuclear winter came out, which is terrible, and Michael explained it in his article, his Cal Tech article of January 2003.
And the whole global warming thing, I just couldnt imagine how this could come forth and go as far as it did, how people could develop models that were imperfect and believe those models, and how far it has carried. Its amazing to me.
And I think the most important thing that Michael Crichton has been arguing is that science must be respected. Objectivity is the thing we need. Politics in science doesnt go. Consensus science isnt science.
Im going to devote my remaining yearsIve still got a little left. Im going to go out kicking and screamingto try to help stop the world from worrying so much about human-induced global warming.
Yeah, were going to have some human-induced global warming. I believe that. I believe CO2 is going up and were going to have warming maybe 0.3 degrees centigrade for a doubling of CO2, not two-to-five degrees centigrade that as the models have been pushing.
Theres a basic flaw in these models, and this is what they do. They take the energy gain that the doubling of the CO2 will bring, warm the surface a little bit with that, get more evaporation and more rain. Nobody doubts this will happen.
However, its what they do with the rain. They take the rain. It goes up into the atmosphere. The condensation warming takes place, and they moisten the atmosphere, more evaporation from the CO2 gain, more rain, more water vapor in the upper troposphere, more blocking of long-wave radiation into space and the globe warms. Thats called the positive feedback loop, and thats where five or 10 times the warming comes.
If that didnt happen, the warming would be quite modest, .2, .3 degrees centigrade or something like that. But the error is in the positive feedback loop. Its negative. Its negative. As you get more rain, yes, you moisten the area around the rain, but the air that goes up has to come down, either around the clouds or way out from the clouds on the other side of the globe. And that will dry, and there will be more IR lost to space.
So, thats how I see it. Now, what do I forecast? I think Im going to make a better one than anything you read in the papers from these models. But the globe is warming. Theres no doubt about it. But this is a natural change. Were coming out of the Little Ice Age, and weve had it warm, then cool, then warm.
For instance, the globe warmed a great deal from 1910 to 1940, and then in the middle 40s to the middle 90s, the globe somewhat cooled. And now its been warming again, and I think in five, six, eight years, were going to see this warming trend stop. I think well see some slight cooling as we saw from the middle 40s to the middle 70s, and were going to understand what causes climate change. Yes, the globe is warming, but its natural and its due to the ocean circulation differences.
So I was just amazed that Michael Crichton, not having been down in the trenches for 50 years with this god-awful data sets we deal with, could come out and have a view like I have, and to have the courage to push it forth and stand by himself with it. And I think thats just wonderful.
Now tropical storms. Thats where Ive done most of my work. We have seen the last two years tremendous damage along the U.S. coast, and there are medicine men all around, coming out of the closets. Weve already seen two published papers that the media has jumped on, and so on, and said this is due to global warming and were responsible for global warming, so we gotta cut down on fossil fuels now to stop these storms from coming in! Now thats just malarkey.
Ive looked at all the global data. Nobodys looked at more tropical cyclone data around the world than me for a longer period, and I can tell you, things are not worse now. What made the damage the last couple years so large is these storms were in an active period. Weve been in an active period since 1995. What made the last two years so active? Theyd been very active seasons, but not much more than the other seasons, most of the other seasons weve seen since 1995. But the steering currents, the trough and ridge patterns that set up in the Westerlies drove the storms west. It was the steering currents that brought them in. It had nothing to do with global warming. Theres no reason. We havent had enough global warming to affect tropical storms one way or the other, and the odds verify that.
So anyways, I would like to echo my great admiration for Michael Crichton, standing up by himself for the truth on this thing, all alone, just about. I found a kindred spirit in him. And its not that I knew much about him before this. I even askedI heard somethingER, and I asked my daughter, I said, Is that a sequel to that movie ET they had about 20 years ago?

I dont know much about Michaels fiction, but I know what he has told in the speeches, and I hope you write this one up so we can read it. I appreciate coming here. Lets hope that Michael Crichton keeps trying to keep people honest with facts. Thanks.

Im going to really quickly, and this wont take long. Im going to introduce you to three friends of mine. I found myself on the wrong side of several issues, on the wrong politically correct side
Thats me in the middle, or at the bottom, way in the back so you cant see me. These other three guys are friends of mine. I havent met any of them, but I want to tell you about them, three people who landed on the wrong side of consensus.
The first is Alfred Wegner. How many of you have heard of Alfred Wegner before? Yeah? Twelve of you. Cool! The rest of you, I want you to read about him. He started out as an astronomer, then he became a meteorologist and climatologist, and then he started playing geologist. And he came up with a concept thats sort of illustrated in the upper right, the idea of Pangea. Born in 1880, a bunch of stuff about him. But the nice thing about him is he was this multidisciplinary guy. He started off in astronomy. Then he got into meteorology. He pioneered the use of weather balloons and wrote a textbook.
And then he got into this geology stuff. He noticed that there were certain fossils and geological formations that were identical on both sides of the Atlantic, like the oil in Africa matched up with the oil in South America. And if you look at a map, they match up pretty closely, and there were some mountains and some other things. And Orthodox science said once upon a time, there was a bridge across there, and Wegner said, Well, I dont think so. I see these diamonds, and the Appalachians match the Scottish highlands and other stuff.
And he came up with this crazy idea that the continents had once been connected, and this term Pangea is the Greek for all the Earth. Well, that didnt sit too well with the orthodox science. The reaction there in the red was uniformly hostile and often exceptionally harsh and scathing. I mean, this guy was bad news, and he was soundly rejected by the science establishment for a long time. He died in the 1930s and it wasnt until much later that he was vindicated. But this is an example of a guy from the University of Chicago, footloose hypothesis, considerable liberty, less bound with restrictions and by awkward ugly facts than most of the tribal theories.
Well, he was vindicated. Increased exploration of the Earths crust and the understanding of plate tectonics proved that Wegner was right all along. And this is something interesting that Wegner said. Only by combing the information furnished by all the Earth sciences, everybody working together, can we hope to find truth. We have to be prepared for the possibility that each new discovery may modify the conclusions we draw.
Richard Feynman, Nobel-winning physicist, said, The best scientists are continually trying to prove themselves wrong. Now, Im a scientist, and its going to sound like Im criticizing scientists, and I find not very many scientists actually do this, and I have to say sometimes Im guilty of not doing this either. Its a lot easier to try to prove yourself right.
J. Harlan Bretz, known as a catastrophist. How many have heard of J. Harlan Bretz before? If you lived in the Pacific Northwest, you might have heard of him because hes more near and dear to us. He looked around eastern Washington, eastern Oregon, the Columbia Gorge, and he noticed these places that are pretty dry now, but there was evidence that something really big had happened.
Like the one on the bottom is a little bitty waterfall thats in this giant track of a huge waterfall, and he said, What could it have been that caused this? From the air, you can see giant ripples, just like ripples in sand on the beach, and then these rocks that are scattered all over that came from somewhere else, maybe from outer space. Who knows?
Well, Bretz studied the Columbia Gorge. He was a geologist, and he built a case that the Columbia Gorge and the scablands of eastern Oregon and Washington were eroded by a cataclysmic flood from a source that was at that time not known.
At that time, science had a theory called uniformitarianism. Say that three times real fast. That there were only slow, gradual processes in geology, and if we couldnt see it happening right now, then it never happened before. And his idea was that something catastrophic had happened, so they came up with this idea that he was called a catastrophist, that he was flaunting catastrophe too vividly in the face of the uniformity that it lend to scientific dignity, etc. This is what the geologists said.
Finally, they found the source of the water in the 1940s. He was in his 90s by then, and it turned out it was the ancient Lake Missoula in Montana, which formed after the ice melted after the last ice age, and today the floods are known as the Missoula Floods, or often the Bretz Floods in his honor. And in one of these expressions of humble pie that I find kind of cool, geologists got together and telegrammed him and said, We are now all catastrophists. So, were with you, J. Harlan.
The last guy is the father of El Niño, Gilbert Walker, who was knighted after his death. And he came up with this crazy idea that there was this oscillation in the Pacific involving high and low temperature and pressure that was somehow connected with the long-observed El Niño phenomenon on the west coast of South America. He was studying the Indian monsoons. And a lot of people made fun of him.
The problem was that he couldnt figure out how to predict El Niño, and because he couldnt predict what was going to happen, his contemporaries said, well, it doesnt exist. If you cant predict it, it doesnt exist. The really funny thing is, we still cant predict it. Even a few months in advance, we cant predict whats going to happen with the El Niño southern oscillation, but we know it exists. We know it exists.
It wasnt until 1957, 58Gilbert Walker died in 58, so he began to see the fruits of this happeningthe first global measurements of the ocean and atmosphere were made, and it happened to coincide with a warm event or an El Niño, and he was vindicated.
Conclusion. First of all, read about these three. How many have never heard of Gilbert Walker before? Never heard of him before. Lots of you. Okay. Gilbert Walker, J. Harlan Bretz, Alfred Wegner. Read about them. Great stories.
But the history of science is filled with stories like those, unpopular ideas which conflicted with consensus and which proved to be true. Thank you for your attention.
President, The Independent Institute
Thank you, George. We have many questions. Well try to get through as many as we can.
The procedure I was going to use was I would read them and direct them to whoever is being asked.
Our first question is for Michael Crichton. It says, You have written about how the old media dinosaurs would collapse with the digital revolution, but now you oppose Googleplan to scan books research. Is this a losing battle?
Is this a question about the Authors Guild lawsuit? I mean, is that?
Oh, okay. Well, Im not really very knowledgeable about it. Im sorry. Next question.
Next question. How do we tell genuine disaster predictions from the ones which are made up?
Im still on? Okay. Im often asked this, and I think if any of you have had any experience in litigationand unfortunately, I have, you knowyou understand that in a legal context, there is a tremendous onus that is placed on somebody once theyve stated a falsehood, and they are sort of never really trusted again. And I think, without particularly pointing to any of the people that I was talking about this evening, if you just look at the general set of scares that weve been subjected to in the last 50-odd years, it would give you a lot of reason to be skeptical just at the outset.
And you know, I think that theres a lot of reason to thinkone of the most difficult discussions that I have is people say we have to act now, and I say, why? We dont have to act now. We can act in 20 years. If you wantin fact, you can act in 50 years. If you look at the speed with which this country electrified and compare that to what it might take if, in fact, we were to really decide we have to convert the entire energy economy of the United States to non-polluting sources, its a huge problem, but we can do it, I think. We would first of all cover the entire state of Massachusetts with solar panels, but
or perhaps part of Texas.
The real question is, do you have to do it now? And the answer is no, you dont. And since solar panels are getting better every year, since the cost of electricity generated by all these sources is declining, why do you have to do it now? Particularly since there are a number of thoughtful people who think this is a problem that may very well take care of itself.
In other words, a hundred years ago, there were no airplanes and there were essentially no automobiles. Now, theres 10,000 airplanes in the sky at any given moment, and millions of automobiles, and we all sit in traffic cursing each other. But the question that I have is, do you really believe that 100 years from now, we will still be living exactly this way? I dont think so at all.
Next question. This is for Michael, and some of the other panelists might be interested in commenting also. What do you think of the UC San Diego study that reviewed 928 peer-reviewed articles, but found not one that challenged the consensus that global warming is human induced? Go ahead. Anyone.
You want to do it?
William M. Gray
Excuse me. Those articles found that human-induced global warming was notwas human induced or not human induced?
The claim was that they reviewed 928 peer-reviewed articles and there was not one that challenged the consensus view.
William M. Gray
You want me to answer that?
William M. Gray
There is an article in Science by a woman named Naomi Oreskes who did a Google search on the term climate change, and according to her research, none of the articles that she found suggested that anything besides human-induced climate change was really a significant factor in climate change itself.
Its been widely refuted by a lot of people. There are literally hundreds of journal articles, which indicate that natural variations are a major component of climate change. Now, I dont know anyone that denies that human influences affect climate. I think we all do. Mostly, its a matter of degree, and many people believe that natural variations are more significantsome much more significantinfluences on climate than the human component is. Thats certainly what I believe. I dont want to speak for Bill Gray, but I think he believes that, too.
None of us really knows whats going to happen in the future, but I think in terms of whats happened in the past, many of us believe that the natural variations are very, very large indeed.
William M. Gray
Well, Id like to make a comment. It just shows you how weve all been brainwashed. Thats what that article shed, and of course, the people that publish papers, most of the journals are a bitthey like to reject papers that dont follow the conventional view, and most of the people that get research and funding have to follow the conventional view. So it doesnt surprise me that the majority of people dont challenge it, but I wouldnt think all of them would follow that. All we can say is brainwashing. Weve all been brainwashed.
My understanding of what Oreskes did was that she did, as George said, used certain keywords, and you can enter those keywords in the database and come out with the same subset of articles that she had. But, in the last 10 years, there were approximately 11,000 climate articles, give or take, of which she found some 968 or 978, and she concluded that, as David said, none of them had any confirmation of any thesis except anthropogenic global warming.
Well, the articles have been reviewed again, and what no one will say is that it seems as though, in fact, the abstracts that were claimed to have been read werent read, because the biggest set of articles among the 900-odd, is something like 40 percent have actually nothing to do with climate at all, or temperature, anyway.
The next question isand this is also for Michaelwhat do you think about the prediction of death from the avian flu?
Do you mean do I think its going to be a pandemic? Is that what that question is?
Yes, thats the question.
How would I know that?
Look. The presumption is that the 1917-18 flu was an avian flu. Flu virus can mutate rapidly. The presumption is that at that time, the lack of immunity that people have to the avian flu decimated them because the avian virus, which only affects birds and people who are in direct contact with birds, jumped into another influenza virus and ran across the road. And the concern is that this will happen again.
I dont know if itll happen again. The only thing that I would suggest to you is that one procedure that people use now to make fear is they say, I dont know the answer, so lets all be afraid. Another way to do it is to say, I dont know the answer, so lets stay calm and try to find the answer.
One thing I might addthis relates to a number of the questions alsois, one of our fellows is an economist by the name of Bruce Yandle. Hes an economist at Clemson University. Hes done a lot of work in law and economics, and he coined a term that is used commonly to describe the process of adopting and supporting different government measures. Its called the Baptist/bootlegger alliance.
And what he means by that is that every single government policy that is adopted is a combination of true believers who believe, for whatever purposes, that the outcome of that measure will be something positive, is the way they see it, in alliance with interest groups that use government measures for their own purposes to shift resources, to use government restrictions against the competitors, whatever, to enrich themselves through government power.
And I would suggest that the flu epidemic, like many of these crises, need to be looked at a little more closely to see what kind of interest actually are talking about them, and of course, the controversies over climate change is part of that question.
Another question isand this could be for any of the panelistsare not many of the negative forecasts of dark consequences based on computer-simulated models lacking in hard data? This could be, I suppose, the climate models or other models.
The atmosphere is very, very complex. Its like a teenager. And to boil down the incredible complexitywe call it a chaotic, nonlinear system, which means its really complicated and we dont fully understand itinto a set of mathematic equations is a really tough thing to do. We know that because I think we all know that weather forecasts dont work real well more than sometimes a few hours in advance, usually a few days in advance, and most weather forecasts now are done with computer models. Were getting better, but we still have a long way to go.
So, the complexity is still so overwhelming that it escapes our ability to simulate it mathematically. It really would be like simulating the behavior of a say, a two-year old. You put in the governing equations that affect a two-year old, the eating habits or potty habits or sleep, or what have you, and try to simulate that with a computer, and it would be a really tough thing to do, and its almost as hard in the case of the atmosphere.
Heres a question. This is for Michael. It says, Youre rightly critical of hysterical fear-mongering writings, yet wasnt the subject of one of your books nanotech run amok? Please explain.
You know, a lot of my books have been about sort of science gone wrong, and Im always surprised that anybody takes it seriously.
When Jurassic Park came out, there was a congressman who was going to introduce legislation banning any research leading to the creation of a dinosaur.
I held my breath hoping to see this happen, but apparently somebody whispered in the guys ear that it was just a movie.
The book that I wrote about nanotechnology is a sort of Frankenstein story, and it discusses technology that is a) impossible at the moment, and b) impossible next year, and c) impossible probably 10 or 20 years from now. I dont really think theres a reason for anybody to be distressed. Enjoy the book.
I enjoyed the book, Ill tell you that. Theres a number of questions that are asking about your views of the op-ed in todays Chronicle. Is there anything you want to say in response to
No. You know, I only glanced at it briefly, but it looked to me like there were two articles and they were both on the same side of the issue. Is that not right?
What was it?
What was thewhat was the op-ed?
I dont know. I dont live here. I was just, you know, coming in from the airport.
The interesting thing about the op-ed is that when we announced our program, we made it clear that Michael was not coming to speak on global warming. He was coming to speak on the issue of politics and science. But, clearly that touches significantly on the global warming debate, and the irony, of course, is that his topic is on the politicization of science, and it seemed like the very response people had in some quarters was the politicization of science.
And where theyon the one hand, people didnt believesome people dont believethat Michael should be speaking on the subject, they keep on demanding that he address the topic. So theres a number of problems, I think, in all of this.
Lets see. Okay. We have time for just two more questions. Since youve addressed the issue of fear and complexity, what is your prognosis for the future of informed analysis of environmental issues? Are you optimistic, in other words?
You know, Im a congenital optimist, and I think its a characteristic of personality rather than a recent assessment of the situation. Bill Gray and I both did some Senate testimony a few weeks ago, and I dont know what his reaction was, but it was the most depressing experience of my life, you know, short of major surgery. You know, to perceive that any kind of objective assessment could occur in this kind of carnival setting, it wasI dont want it was more like a Stalinist show trial, but it had highly theatrical aspects that did not appear to represent the search for truth.
I think that we will finally have to come to terms with the kinds of issues that I was talking about today in terms of Yellowstone. Its going to be too obvious that we dont know what were doing with the environment, and its going to be too obvious that we really dont understand it and we ought to stop pretending that we do. And once we begin to treat it as something we dont really understand but were working to try and manage, well have much better results. But its going to be a large change.
Last question is, your work or talk on complexity theory certainly seems to explain a great deal of whats happening, or our lack of understanding of whats happening. How would you suggest that be used to look at economic questions?
My understanding is theres plenty of interesting complexity theory among economists already. I mean, I think thats happening, is it not?
Thats right. Yes, definitely.
OK. I want to thank Michael Crichton for taking the time and interest in putting himself, as Bill has said, on the line on some of the most important issues that we all face in the U.S. and around the world. Information is important, but information that is not based on reliable evidence can be very damaging. Michael, I think, deserves a special applause, and if youd join with me, I want to thank him again.
I also want to thank our panelists, Sallie Baliunas, Bill Gray and George Taylor for their joining with us and their wonderful comments. I want to thank Bruce Ames also for his wonderful comments.
As I mentioned, Michael will be out in the lobby in just a few minutes to autograph his book. For those of you who do not have a copy, there are plenty of copies both in cloth and paperback. You can also register for an event on December 13th. Thank you for joining with us and making this such a successful program. We look forward to seeing you in the future. Thank you and good night.
