How
A Pseudo-Scientist
Duped The Big Media -- Big Time
by

Lomborg's new book, The Skeptical Environmentalist, brings us
glorious news. The world's environment is getting better, not
worse. Contrary to what the experts have been telling you, forests
are spreading, air and water pollution are improving, global warming
will have mild effects, and there won't be any food shortages
as the world's population grows. And there's no need to worry
about the ozone hole, species extinction, or acid rain; all those
pesky environmentalists have just been exaggerating to try to
scare you.
If
this sounds too good to be true, that's because it is.
The
Skeptical Environmentalist presents itself as a work of impartial
scholarship, an attempt to test the validity of various environmental
concerns through a careful analysis of the evidence. In fact,
it's a polemic, an intellectually dishonest tract filled with
glaring omissions, appalling errors of fact and analysis, and
inaccurate characterizations of contrary arguments. There are
some valid points as well -- Greenpeace and other advocacy groups
have distorted scientific information for their own ends -- but
Lomborg must be read with a very skeptical eye.
Unfortunately,
the media reaction has been surprisingly un-skeptical. The book
has become a runaway hit on both sides of the Atlantic following
a wave of credulous features, book reviews, and Lomborg guest
essays published in many of the English-speaking world's most
respected newspapers and magazines.
Before
the book was even available in the Britain, newspapers were signing
its praises. The London Observer's environment correspondent,
Anthony Browne, announced it had "demolished almost every
... environmental claim with a barrage of official statistics.
"The London Times science correspondent reported Lomborg's
global warming claims in a story without other sources. The Economist
gave a glowing review and invited Lomborg to write a 2,500 word
essay, while the more liberal Guardian published a three-part
series. Time International opined that "Of all the sacred
cows, only global warming remains unslain" by Lomborg.
The
coverage quickly generated a maelstrom of criticism from leading
scientists --including Lomborg's own colleagues at the University
of Aarhus. Many of his claims were publicly discredited, but you'd
never know that from reading the subsequent coverage in this country.
The New York Times carried a sympathetic 2,000 word feature on
the book, calling it "a substantial work of analysis."
The Washington Post Book World was gushing in its praise, calling
it "a magnificent achievement" and "the most significant
work on the environment since ... Silent Spring." The Post
reviewer, Dennis Dutton, a philosopher in New Zealand who lectures
on "the dangers of pseudoscience" even decreed that
the book "is now the place from which environmental policy
decisions must be argued."
How
did the supposedly skeptical media get so taken in? Weren't there
clues that should have cast suspicion on Lomborg's motives and
analysis? Well, yes and no.
At
first glance, Lomborg looks credible. Unlike past anti-green polemicists,
Lomborg is a tenured professor at the environmental studies institute
of a prestigious university. He's a self-declared "environmentalist
... former Greenpeace member [and] left-wing sympathizer"
who doesn't eat meat because he doesn't want to kill animals.
Lomborg
isn't an environmental scientist and has never published a scientific
paper on climate change, ecology, atmospheric pollution, or any
other topic he takes on in his book.
More
importantly, his book is published by Cambridge University Press,
an academic publisher that supposedly peer reviews manuscripts
prior to publication.
"He's
a tenured professor at a major university published by an important
press," says Bruce Lewenstein, who teaches science communications
at Cornell University, after looking over Lomborg's bio. "If
someone with some credentials is questioning the conventional
wisdom, that's a story."
It
may be a story, but it's one that smells fishy from the very first
sniff.
Lomborg
isn't an environmental scientist and has never published a scientific
paper on climate change, ecology, atmospheric pollution, or any
other topic he takes on in his book. That's because he's not even
a natural scientist, but rather a political scientist with a background
in statistics and game theory.
"Here's
one guy taking on a whole spectrum of issues who has never written
a paper on any of them and is in opposition to absolutely everyone
in the field, Nobel prize-winners and all," says Stuart Pimm,
a conservation biologist at Columbia University who says virtually
all of Lomborg's facts on biodiversity are simply wrong. "It
ought to have raised some red flags." Political reporters
often follow the money; science reporters should follow the data.
Those that did discovered that many of the book's 2,500 footnotes
led not to hard data, but to newspaper stories, Web pages, and
magazine interviews with rival scientists. Some stunning assertions
-- that "our oceans have not become defiled" for instance
-- aren't substantiated by any research at all.
"He
asserts with no analysis that only the mildest [climate change]
impacts will happen and that the dangerous ones won't happen,"
says Stanford University's Stephen H. Schneider, lead author of
several chapters of the International Panel on Climate Change's
reports. "That the media sucked it up is really incredible."
"Journalists
feel they need to give equal emphasis to a single skeptic on one
side and, say, the scientific consensus of several thousand of
the world's scientists on the other."
Part
of the problem is the media's propensity to treat scientific disagreements
as they might a political one: quote both sides and let the reader
decide on their own. But, as most science writers know, such an
approach is entirely inadequate for reporting on science and technology
issues. It's important to report on bold, unorthodox theories,
because some hold true and lead to new discoveries. But the science
journalist has a duty to place them in their proper context: the
shared, established opinion of dozens or hundreds of experts in
the field does in fact carry more weight than that of a single
dissenter.
"Journalists
feel they need to give equal emphasis to a single skeptic on one
side and, say, the scientific consensus of several thousand of
the world's scientists on the other," as in the debate over
climate change, says Lisa Sorensen, staff scientist at the Union
of Concerned Scientists in Washington. "This leads readers
and viewers to think these opinions have equal weight when, in
fact, they do not."
Not
everyone sees it this way. Anthony Browne, whose articles in the
London Observer first brought attention to the English-language
edition of The Skeptical Environmentalist, says most environmental
journalists spend most of their time "acting as publicists
to those who have a vested interest in scaring people about the
state of the environment." He said that when somebody like
himself airs the views of skeptics, "those who believe with
a passion that we are all doomed heap anger and contempt on them."
Browne says journalists shouldn't test "the validity of certain
bits of science," but simply judge if someone appears credible
and give them an airing to foster debate.
The
editor in chief of The Economist, Bill Emmott, stands behind Lomborg's
book and denies that it has been given a free ride by the media.
"The real problem for the critics is that as far as we can
see his data is incontrovertible. That is awkward for those who
have made claims in the past that the data flatly contradicts,"
Emmott says. He said that in all the debate, he had yet to see
a critic establish that the book contains "egregious"
errors. "He has wiped the floor with his opponents, which
is probably why he has created such ire." Grist Magazine
has compiled a series of articles from leading scholars that illustrate
how wrong Lomborg and Emmott are.
Several
scientists interviewed for this article were dumbfounded that
with all the scientific and environmental expertise available
in the United States, the Washington Post's book review assigned
the book to a philosophy professor in New Zealand with no more
expertise to assess the arguments than the Post's own science
reporters. The reviewer, Dennis Dutton, was chosen because of
his "neutrality, remove, record ... and his interest in the
environment," according to the paper's Book World editor,
Marie Arana. She said that assigning the book had been the subject
of an unusually wide-ranging debate, which resulted in a decision
not to assign the book within the newsroom.
Dutton,
whose popular Arts and Letters Web site includes a paean to the
late environmental skeptic Julian Simon in its list of classic
articles, declined to comment for this article. "It is the
accuracy or inaccuracy of the book that is at issue, as far as
I am concerned," he wrote by e-mail. "If you think the
book is factually wrong, and if reviewers have been misled, I'd
be keen to learn how."
But
many of Lomborg's most troubling deceptions don't require scientific
training to detect, and should have been obvious to any editor
with even a passing interest in the environmental debate. Much
of the book is deliberately misleading. Lomborg devotes entire
chapters to "revealing" that we are not running out
of oil or metals, although virtually nobody in the environmental
movement has claimed otherwise in the past twenty years. He also
marshals statistics to prove that human life expectancy and the
global Gross Domestic Product have improved over the past two
centuries and that the green revolution increased agricultural
production, as if anyone is arguing the contrary. Lomborg shows
the Kyoto agreement will have only a slight impact on global warming,
apparently unaware that the treaty is indeed conceived as a "down
payment" on reducing carbon dioxide emissions.
Much
of the media -- conservative and liberal alike -- were duped by
the imprimatur of Cambridge University Press, whose reputation
has been damaged by the publication of Lomborg's book.
Conservatives
love Lomborg's message because it suggests that the status quo
is pretty good. The Cooler Heads Coalition -- a group spearheaded
by the Competitive Enterprise Institute which seeks to "dispel
the myths of global warming" -- helped kick-off The Skeptical
Environmentalist's U.S. release by sponsoring Lomborg's very own
Capitol Hill briefing on October 4th. Not surprisingly, conservative
columnists have heaped praise on the book. Katherine Kersten,
senior fellow at the Center of the American Experiment, told her
Minneapolis Star-Tribune readers not to be taken in by "environmental
fearmongering" and that "celebration, not despair, is
in order." Steve Chapman of the Chicago Tribune questioned
how environmentalists have "resisted the impulse to carry
Lomborg off on their shoulders, wildly celebrating all the achievements
of our era." The reason: environmentalists take "a solemn
vow of melancholy."
Asked
about how he assessed Lomborg's work, Chapman said that he didn't
pretend to be a scientist and might change his opinion of the
book if it were shown to be fraudulent. "All a layman like
myself can do is try to learn about a subject by listening to
what scientists on either side say and make a judgment of who
is right," he said. "We do the same thing with non-scientists
like economists and military people, whose knowledge is far deeper
than our own."
Much
of the media -- conservative and liberal alike -- were duped by
the imprimatur of Cambridge University Press, whose reputation
has been damaged by the publication of Lomborg's book. "Despite
the sales that have been generated, CUP's credibility and reputation
will suffer," says Jane Lubchenco, distinguished professor
of zoology at Oregon State University and past president of the
American Association for the Advancement of Science. "Many
of us have inquired of our Cambridge contacts how they could have
published a book that so clearly could never have passed peer
review."
The
book was acquired by CUP's social science group, rather than its
natural science division. Editor Chris Harrison declined to comment
on rumors that natural science editors had been kept in the dark
about the book until a very late date. He said by e-mail that
he had been very skeptical about the book when it first landed
on his desk, and was surprised when all four of the scientific
"referees" who reviewed the English manuscript recommended
it for publication. He said referees always remain anonymous,
but that all four were "senior figures . from leading departments
on both sides of the Atlantic" and included two from "environmental
science departments, one from climate science, and one from a
social science department."
Harrison
said he had no regrets about publishing the book and that Cambridge
University Press prided itself on publishing a variety of voices.
"The book has been noticed and debated and that is surely
a valuable contribution to public and academic debate in an open
society," he said, adding that he himself was a "green
tinted liberal" and not part of some conservative agenda.
Others
dispute that The Skeptical Environmentalist's contribution will
be positive.
"This
book is going to be misused terribly by interests opposed to a
clean energy policy," says Ms. Sorensen of Union of Concerned
Scientists, whose organization is publishing a series of scientific
critiques of Lomborg's science. "Hopefully that will help
counter the claims and minimize the damage that could be done
by a book like this."
Earth
Day Network's Grist Magazine.com commissioned a series of reviews
by prominent scientists from the fields that Lomborg tackled in
his book.
