========================================
On December 26, 2004, a magnitude 9.0 earthquake occurred off the coast of
Northern Sumatra. The massive temblor, the largest in 40 years, spawned
tsunamis that killed more than 150,000 people. The next day, a colleague at a
think tank emailed me to ask if I had any opinions about the new Michael
Crichton book, State of Fear.
Although State of Fear is a fictional thriller about ecoterrorism, its real
thesis is the politicization of science, in particular climate change and
global warming. Because global warming is a highly-charged political subject,
CrichtonÕs book has received a lot of attention in the press, including a
review by Washington Post columnist George Will (Will, 2004). My colleague
closed his email with a little joke:
ÒP.S. - IÕm also anxious to see if anyone blames this weekendÕs
tsunami in Indonesia on global warming.Ó
We didnÕt have long to wait. A few hours later, the CBS evening news broadcast
did just that. Citing unnamed Òclimate expertsÓ, they put up a graphic that had
only the words Òglobal warmingÓ and ÒtsunamisÓ. News anchor Dan Rather then
stated:
ÒClimate experts warned today that tsunamis could become more
common around the world and more dangerous. They cite a number of factors,
including a creeping rise in sea levels believed to come from global warming
and growing populations along coastal areas.Ó
A Russian politician was less circumspect. The Deputy Chairman of the Russian
Duma (parliament), Artur Chilingarov, told the Russian news agency Ria Novosti:
ÒThe reason for the earthquake and a gigantic tsunami which
killed several tens of thousands of people in South and Southeast Asia was
probably a global climate change...scientists have registered lately a change
of the average temperature, which is now growing at fantastic rates. These
seemingly insignificant temperature changes allow the atmosphere and oceans to
accumulate additional energy...Ó (Anonymous, 2004a).
I have had my own experiences with the politicization of climate science. In
1995, I had a short paper published in the prestigious journal Science (Deming,
1995). I reviewed how borehole temperature data recorded a warming of about one
degree Celsius in North America over the last 100 to 150 years. I closed the
manuscript with what seemed to me to be a remarkably innocuous and
uncontroversial statement:
ÒA cause and effect relationship between anthropogenic activities
and climatic warming cannot be demonstrated unambiguously at the present timeÓ
(Deming, 1995, p. 1577).
The week the article appeared, I came into my office one morning to find a
voicemail message from a reporter for National Public Radio. He wanted to
interview me concerning my article in Science. Visions of glory danced in front
of my eyes. I was going to be on national radio. Surely, it was only a matter
of time before I would be a regular guest on the McNeil-Lehrer news hour on
PBS. Excited, I called the reporter back. But all of my fantasies were
immediately dispelled. The reporter focused in on the last sentence in the
Science paper. He asked me, did I really mean to say that? Did I really intend
to imply that the warming in North America may have been due to natural
variability? Without hesitation, I said ÒyesÓ. He replied, ÒWell then, I guess
we have no story. ThatÕs not what people are interested in. People are only
interested if the warming is due to human activities. Goodbye.Ó And he hung up
on me. It was my first realization that the media intentionally filter the
information the public receives.
A year later, I received a telephone call from an author working on an article
for International Wildlife, a magazine published by the National Wildlife
Federation, an environmental advocacy group. We discussed some of my work, and
talked about the implication of borehole temperature measurements for global
warming. Subsequently, the Editor of International Wildlife sent me a draft
article for review. I was horrified. My work and comments had been taken out of
context and used in such a way as to exaggerate the magnitude of climate
change. I made some pointed comments, and the article was toned down a little.
I later learned that the author of the International Wildlife article was not a
scientist, but a lawyer. I had been naive. I had assumed that everyone was like
me—they were interested in the truth. But a lawyerÕs job isnÕt to discover
truth, itÕs to win an argument. Neither is an advocacy organization interested
in truth—they are committed to advocating a certain position regardless
of the facts.
With the publication of the article in Science, I gained significant
credibility in the community of scientists working on climate change. They
thought I was one of them, someone who would pervert science in the service of
social and political causes. So one of them let his guard down. A major person
working in the area of climate change and global warming sent me an astonishing
email that said ÒWe have to get rid of the Medieval Warm Period.Ó
The Medieval Warm Period (MWP) was a time of unusually warm weather that began
around 1000 AD and persisted until a cold period known as the ÒLittle Ice AgeÓ
took hold in the 14th and 15th centuries. Warmer climate
brought a remarkable flowering of prosperity, knowledge, and art to Europe. As
the temperature increased, so did agricultural yields. Marshes and swamps dried
up, removing the breeding grounds of mosquitoes that spread malaria. Former
wetlands were converted to productive farmland. Infant mortality fell, and the
population grew. From 1100 to 1300 AD, the population of Europe increased from
about 40 to 60 million (Moore, 1995). The surest sign of the warming climate in
Europe was the settlement of Greenland by Vikings from Iceland. The Greenland
settlements reached a height of prosperity in the 12th and 13th
centuries when 3,000 colonists occupied 280 farms. The settlements came under
duress in the late 14th century due to the onset of Little Ice Age
cooling; they finally perished in the 15th century. The existence of
the MWP was recognized in the climate textbooks for decades. But now it was a
major embarrassment to those maintaining that the 20th century
warming was truly anomalous. It had to be Ògotten rid ofÓ.
During the early 1990s, an important reference book for those working in the
area of climate change was Climate Change: the IPCC Scientific Assessment
(Houghton et al., 1990). The IPCC, the Intergovernmental Panel on Climate
Change, was the major international organization concerned with the dangers of
global warming. And yet a skeptic could open the IPCCÕs own reference text and
see that 20th century warming was dwarfed by the MWP (Houghton et
al., 1990, p. 202). When the 20th century warming was placed into
the context of a thousand years of history it appeared to be virtually
insignificant. If people were going to be convinced of the danger of global
warming, the MWP clearly needed to be erased from history.
In 1998, Michael Mann, a climate researcher at the University of Massachusetts,
published a paper in Nature where he and his colleagues claimed that
temperatures in the late 20th century were warmer than any time
since the year 1400. A year later, the same authors extended their analysis
back to the year 1000 (Mann et al., 1999). In the Mann et al. (1999)
reconstruction of temperature, the MWP simply vanished. The analyses by Mann et
al. (1998, 1999) resulted in graphs of mean global temperature over the last
1000 years that had the shapes of hockey sticks. The graphs showed that mean
global temperatures were uniformly monotonic over the last millennium, abruptly
rising in the 20th century.
Mann et al. (1999, p. 759) concluded that Òthe latter 20th century
is anomalous in the context of at least the past millenniumÓ. This conclusion
was greeted like the triumphal return of Jesus Christ. Decades of work was
overturned by one journal article. The MWP had been reinterpreted out of
existence.
Within a few days, the research by Mann and his colleagues passed from analysis
to fact. On March 3, 1999, the University of Massachusetts issued a press
release with the headline Ò1998 Was Warmest Year of Millennium...Ó On March 22,
1999, the Atlanta Journal and Constitution published an editorial titled ÒThe
Facts About Global WarmingÓ wherein they stated:
ÒThe 10 warmest years on record have occurred in the past 15
years...Clearly something is happening to EarthÕs climate, and according to the
scientific consensus, that ÒsomethingÓ probably has two arms, two legs and two
or three cars in every garageÓ (Anonymous, 1999).
Four years later, Willie Soon and Sallie Baliunas (2003) reviewed more than 200
previous studies and concluded that the evidence for the existence and global
extent of both the Medieval Warm Period and the Little Ice Age was well
established. It was hardly a controversial result, yet the Soon and Baliunas
(2003) paper was greeted by a firestorm of controversy. Three editors of the academic
journal in which the study had been published resigned in protest (Regalado,
2003, p. A-3).
Writing in the June 24, 2003, internet version of Scientific American, reporter
David Appell explained Soon and BaliunasÕ sin.
Ò...the consensus view among paleoclimatologists is that the
Medieval Warming Period was a regional phenomenon, that the worldwide nature of
the Little Ice Age is open to question and that the late 20th
century saw the most extreme global average temperatures.Ó
Soon and Baliunas had committed the cardinal sin of violating the new
consensus. They were not the first scientists to get in trouble for violating
consensus. In the 17th century, an irascible Italian mathematician
made people even angrier. When asked if he didnÕt have to honor his enemiesÕ
objections, he explained:
ÒThe conclusions of Natural Science are true and necessary, and
the judgment of men has nothing to do with themÓ (Galilei, 1953, p. 63).
When he was in a less temperate mood (his normal state), Galileo made a more
pointed criticism of human consensus.
ÒThe crowd of fools who know nothing is infiniteÓ (Drake, 1957,
p. 239).
A direct attack on Mann et al. (1999) appeared later in 2003. Two Canadian
scientists, Stephen McIntyre and Ross McKitrick, tried to replicate the results
of Mann et al. (1998), but were unable to do so. In a paper published in Energy
& Environment, they claimed:
ÒThe data set of [Mann et al., 1998]...contains collation errors,
unjustifiable truncation or extrapolation of source data obsolete data,
geographical location errors, incorrect calculation of principal components,
and other quality control defectsÓ (McIntyre and McKitrick, 2003, p. 751).
McIntyre and McKitrick also found that Mann et al.Õs (1998) results could not
be supported by the data.
ÒAn even more serious criThe (sic) particular Òhockey stickÓ
shape derived in the [Mann et al., 1998] proxy reconstruction is primarily an
artifact of poor data handling, obsolete data and incorrect calculation of
principal componentsÓ (McIntyre and McKitrick 2003, p. 751).
A critique of the Mann et al. (1998, 1999) climate reconstructions appeared in
Science in October, 2004. von Storch et al. (2004) pointed out that the
methodology used by Mann et al. (1998, 1999) was flawed. Their reconstruction
technique tended to dampen out, and thus obliterate, past temperature changes.
Although the analysis by von Storch et al. (2004) published in Science was
damning, the language was diplomatic.
ÒThe centennial variability of the Northern Hemisphere
temperature is underestimated by the regression-based methods applied here,
suggesting that past variations may have been at least a factor of 2 larger
than indicated by empirical reconstructionsÓ (von Storch et al., 2004, p. 679).
In an interview, the lead author, Hans von Storch, was less tactful. In the
October 4, 2004, issue of the German magazine Der Spiegel, he referred to the
Òhockey stickÓ graphs of Mann et al. (1998, 1999) as Òquatsch.Ó The German word
quatsch translates into English as rubbish, hogwash, balderdash, bilge, bunk,
hooey, malarkey, or nonsense (Anonymous, 2004b).
As the year 2005 began, the Mann et al. affair began to take on an eerie
resemblance to the case of Emory University professor Michael Bellesiles.
Bellesiles was the author of an award-winning book, Arming America: The Origins
of a National Gun Culture (2000). The revolutionary thesis of Arming America
was that guns had been uncommon in colonial America. The book won Columbia
UniversityÕs prestigious Bancroft Prize for an original contribution to
American history. BellesilesÕ findings were immediately trumpeted as a
revelation with profound implications for the political debate about gun rights
in the United States. Writing in the Chicago Sun-Times, Northwestern University
history professor Gary Wills claimed:
ÒThere is nothing left to vindicate the myth that individually
owned guns were a source of American freedom and greatnessÓ (Wills, 1999, p.
31).
Critics of BellesilesÕ thesis seemed to be confined to a community of ignorant
zealots and gun fanatics who circulated ad hominem attacks on the internet.
Writing in the Atlanta Journal-Constitution on March 18, 2001, Bellesiles
claimed that he had become the victim of a hate campaign waged over the world wide
web (Bellesiles, 2001).
The first intimation in the mainstream press that there might be anything wrong
with BellesilesÕ scholarship occurred on October 3, 2001. The Boston Globe
reported that Emory University had asked Bellesiles to write a detailed defense
of his work. Among the charges against Bellesiles was that he claimed to have
relied upon San Francisco probate records that had been destroyed in the 1906
fire (Mehegan, 2001). A year later, it was all over. An investigative panel
assembled by Emory concluded that Bellesiles Òwas guilty of both substandard
research methodology and of willfully misrepresenting specific evidenceÓ (de la
Merced, 2002). Bellesiles resigned, but without admitting any culpability. In
an effort to save face by rewriting history, Columbia University retroactively
rescinded BellesilesÕ Bancroft Prize (Anonymous, 2002).
Personally, I had doubts about the Mann et al. (1999) claims from the
beginning. Only a few years earlier, the existence of a world-wide MWP had been
documented by an important paleoclimate study, Huang et al.Õs (1997) analysis
of borehole temperature data. As Lachenbruch and Marshall (1986, p. 696)
pointed out many years ago, borehole temperatures are the most robust
paleoclimate indicator we have because they are not a proxy, but a direct
thermophysical record of temperature changes occurring at the surface.
The Huang et al. (1997) study was originally submitted to Nature. I was one of
the reviewers of the manuscript. I told the Nature editors that the article
would surely be one of the most important papers they published that year. But
it never appeared in print. Nature asked the authors to revise the paper twice
and then, after a long delay, ended up rejecting it. While writing this essay,
I learned that McIntyre and McKitrickÕs manuscript had received similar
treatment at Nature. Apparently, it is not enough for the editors at Nature to
simply reject an article that is politically incorrect; they have to delay its
inevitable publication in another journal by tying it up in the review process
for several months.
Not only does the analysis by Huang et al. (1997) show a well-developed MWP, it
also reveals that mean surface global temperature over most of the last 10,000
years was significantly warmer than the late 20th-century value. But
this paper received virtually no attention in the press. After all, it wasnÕt
Òwhat people are interested in.Ó
Two years ago, Michael Crichton delivered a lecture at Caltech titled ÒAliens
Cause Global Warming.Ó The talk was transcribed onto CrichtonÕs website , and
subsequently has been widely circulated on the internet. Aliens Cause Global
Warming is about the politicization of American science over the last forty
years, starting with the search for extraterrestrial life, and ending with
global warming.
How many people remember the peril of nuclear winter? Crichton shows how the
entire concept was Òfrom the outset the subject of a well-orchestrated media
campaignÓ conducted for political ends. A Washington DC public-relations firm
was paid $80,000 to publicize the research. The first appearance of the work in
the peer-reviewed, scientific literature was in the December 23, 1983, issue of
Science (Turco et al., 1983). But the dangers of nuclear winter had been
heralded nearly two months earlier by Carl Sagan in the October 30, 1983, issue
of Parade magazine, a supplement to Sunday newspapers (Seitz, 1986). By 1986,
it was apparent that the conclusions of Turco et al. (1983) were suspect, and
that the entire field of research was highly politicized. Writing in the
January 23, 1986, issue of Nature, K. A. Emanuel (1986, p. 259) noted that
Ònuclear winter research...has become notorious for its lack of scientific
integrityÓ.
In State of Fear, Michael Crichton takes the thesis he first espoused in Aliens
Cause Global Warming and expands it through the vehicle of a fictional
thriller. Fiction can be used very effectively to promulgate social and
political causes. Classic examples include Harriet Beecher StoweÕs Uncle TomÕs
Cabin (1852) and Ayn RandÕs Atlas Shrugged (1957).
State of Fear follows the adventures of lawyer Peter Evans as he is dragged
into a conflict between eco-terrorists and counter-terrorism agents. The goal
of the terrorists is to use advanced technology to induce natural disasters
that can be blamed on global warming. The chief villains are the administrators
of the fictional National Environmental Resource Fund, cynical men whose only
goal is to manipulate the press so as to increase the funding for their organization.
No one is surprised that it all comes down to money.
The novel reads like the screenplay for a Hollywood thriller. Attorney Evans
narrowly escapes freezing to death after falling into an ice crevasse in
Antarctica. Assassinations are not done with routine methods such as guns or
garrotes. People are killed by injecting them with the venom of a poisonous
octopus. In one memorable scene, an attractive young woman can only escape
electrocution by stripping off her clothes. An essential component of the James
Bond genre is high technology. In State of Fear, the reader is introduced to
hypersonic cavitation technology and weather modification by changing Òthe
electric potentials of the infra-cumulus strataÓ (Crichton, 2004, p. 313).
Crichton skillfully and seamlessly intertwines the plot with information on
global warming. In one chapter, attorney Peter Evans is forced to examine the
evidence for global warming in the context of a hypothetical lawsuit. All
uncertainties, failed predictions, and questions concerning the reliability of
the data are brought into focus.
A unique aspect of State of Fear is CrichtonÕs repeated citation of the
scientific literature that contradicts the ÒconsensusÓ on the dangers of global
warming. Among the claims found in State of Fear:
á carbon dioxide stimulates plant growth (p. 421)
á since 1980, the Sahara Desert has been shrinking, not expanding (p. 421)
á the rate of emergence of new diseases has not changed since 1960 (p. 421)
á there are no accurate estimates for the rate of species extinction (p. 422)
á extreme weather, including hurricanes, has not become more frequent (p. 426)
á a renewable-energy technology that can replace the use of fossil fuels does
not exist
(p. 479)
á Antarctica is getting colder, and the thickness of the ice is increasing (p.
193)
á the urban heat-island effect on the temperature record has been
underestimated (p. 384)
Perhaps the most interesting character in State of Fear is professor Norman
Hoffman. Professor Hoffman studies what he calls the Òecology of thought.Ó In a
memorable soliloquy, Hoffman muses how the most prosperous and safe
civilization in human history has become obsessed with doomsday visions and
exists in a Òstate of fear.Ó
ÒHas it ever occurred to you how astonishing the culture of
Western society really is? Industrialized nations provide their citizens with
unprecedented safety, health, and comfort. Average life spans increased fifty
percent in the last century. Yet modern people live in abject fear. They are
afraid of strangers, disease, of crime, of the environment. They are afraid of
the homes they live in, the food they eat, the technology that surrounds them.
They are in a particular panic over things they canÕt even see—germs,
chemicals, additives, pollutants. They are timid, nervous, fretful, and
depressed. And even more amazingly, they are convinced that the environment of
the entire planet is being destroyed around them. Remarkable! Like the belief
in witchcraft, itÕs an extraordinary delusion—a global fantasy worthy of
the Middle Ages. Everything is going to hell, and we must all live in fear.
Amazing.Ó (Crichton, 2004, p. 455).
ÒForemost among the institutions that promote the state of fear
are American universities. The modern State of Fear could never exist without
universities feeding it. There is a peculiar neo-Stalinist mode of thought that
is required to support all this, and it can only thrive in a restrictive
setting, behind closed doors, without due process. In our society, only
universities have created that—so far. The notion that these institutions
are liberal is a cruel joke. They are fascist to the core...Ó (Crichton, 2004,
p. 459).
As the twenty-first century dawns in America, our institutions of higher
education appear to be reverting to their Medieval ancestors. Intolerant and
dogmatic, European universities in the fifteenth and sixteenth centuries were
dedicated to maintaining the intellectual consensus. After attending most of
the European colleges of his day, Paracelsus (1493-1541) characterized his
university education by stating:
ÒI was brought up in the garden where the trees are mutilatedÓ
(Baas, 1889, p. 377).
And what does Crichton himself think? In an appendix titled ÒAuthorÕs MessageÓ,
he lays out his own views in a series of short statements that make it clear he
identifies primarily with the Cornucopian School.
ÒI think for anyone to believe in impending resource scarcity,
after two hundred years of such false alarms, is kind of weird. I donÕt know
whether such a belief today is best ascribed to ignorance of history, sclerotic
dogmatism, unhealthy love of Malthus, or simply pigheadedness, but it is
evidently a hardy perennial in human calculationÓ (Crichton, 2004, p. 570).
Michael CrichtonÕs State of Fear is an exciting and well-written fictional
thriller. But the book is really about how we do science. For ages, science in
Western Civilization has struggled to free itself from restrictions imposed by
theology (White, 1903). That battle seems to have been pretty well won. But the
fight for freedom of thought seems to be never-ending. The new threat comes
from the politicization of science.
Crichton closes State of Fear with a quote from Alston Chase about the dangers
of politicizing science (2004, p. 580). But I have a better quote from Phillip
Johnson:
ÒWhenever science is enlisted in some other
cause—religious, political, or racialist—the result is always that
the scientists themselves become fanaticsÓ (Johnson, 1991, p. 154)
