Former Greenpeace Academic
Slams Radical Greens
by James M. Taylor
It is not unusual for scientists and public-policy experts to present evidence contesting the doom-and-gloom proclamations of environmental activists.
What is unusual, and highly damaging, is for a prominent environmental activist to turn the tables on the Greens themselves.
Danish professor and prominent former Greenpeace member Bjorn Lomborg has done such damage to the radical environmentalist movement with the publication of his scathing book, The Skeptical Environmentalist.
Lomborg, a political scientist, professor of statistics at the University of Aarhus in Denmark, and prominent former Greenpeace member, began his journey from
environmental activist to green-scare skeptic after reading an interview of preeminent
free-market scholar Julian Simon in "Wired" magazine.
Convinced Simon was dead wrong on a number of environment issues, Lomborg and some of his colleagues set out to expose the "errors" in Simon's analyses.
A funny thing happened as the environmentalists sought to prove Simon and the skeptics wrong. States Lomborg, "Three months into the project, we were convinced that we were being debunked instead. Not everything he said is right. He has a definite right-wing slant. But most of the important things were actually correct."
"A Litany" of political ideas
From those beginnings, Lomborg eventually compiled his similar findings in The
"Skeptical Environmentalist."
The book itself, while quite comprehensive and well documented (it includes almost
3,000 supporting footnotes), is not the first of its kind to use objective scientific analysis
to debunk environmentalist myths. Indeed, the substance of Lomborg's arguments and
even the structure of the book itself closely tracks "Eco-Sanity: A Common-Sense Guide
to Environmentalism," authored by Joseph L. Bast, Peter J. Hill, and Richard C. Rue,
published by Madison Books and The Heartland Institute.
What makes "The Skeptical Environmentalist" so noteworthy – and especially to the
mainstream media – is that the book is authored by one of the Green movement's most
prominent members.
With a unique insight into the behind-the-scenes workings of environmental activism,
Lomborg takes special aim at public statements made by such activist groups as the
Worldwatch Institute, World Wildlife Fund, and Greenpeace itself.
Lomborg identifies "A Litany" of political ideas frequently espoused by the groups that
have no basis in scientific fact but have nevertheless been swallowed hook, line, and
sinker by the mainstream media. "The Litany has pervaded the debate so deeply and so
long," writes Lomborg, "that blatantly false claims can be made again and again, without
any references, and yet still be believed." By contrast, one thing Lomborg certainly does
provide in his book is scientific references.
Receiving substantial attention in "The Skeptical Environmentalist" is global-warming
theory. Lomborg observes there are several "wild cards" that come into play when
assessing the effects of carbon dioxide and other greenhouse gases on the Earth's
atmosphere. Those wild cards include the effects of clouds, aerosols, and the sunspot
cycle, as well as the multiplier effect of carbon dioxide. Lomborg notes the warming
effects of greenhouse gases are mitigated by a corresponding increase in solar-reflecting
clouds. As the air begins to warm, it can hold more water, resulting in an increase in
cloud cover. Those clouds then reflect more sunlight back into space, resulting in a
balance – restoring cooling. Satellite readings confirm that global temperatures have not
risen in recent decades, while the Earth has seen a slight increase in cloud cover.
Lomborg presents similar scientific evidence regarding aerosols, the sunspot cycle, and
the multiplier effect of carbon dioxide. He observes that greenhouse computer
programmers fail to properly account for these factors in their climate models. By failing
to account for these wild cards, Lomberg points out, the models conclude we should
already be toasting under a greatly enhanced greenhouse effect. And yet satellite
temperature measurements show no such warming has occurred.
Debunking deforestation
Lomborg also takes environmental activists to task for spreading false propaganda about
global deforestation.
In its 1998 "State of the World" report, for example, the Worldwatch Institute claims
"The world's forest estate has declined significantly in both area and quality in recent
decades." Lomborg documents, however, that U.N. Food and Agriculture Organization
figures show global forest cover has actually increased from 30.04 percent in 1950 to
30.89 percent in 1994.
Lomborg further notes Worldwatch claimed "Canada is losing some 200,000 hectares of
forest a year" due to soaring demand for paper. In fact, Lomborg shows, "Canada grew
174,600 more hectares of forest each year."
The Worldwatch Institute's inaccurate claims do not end with deforestation, notes
Lomborg. In its 2000 report, Worldwatch warned of "record rates of population growth,
soaring oil prices, debilitating levels of international debt and extensive damage to forests
from … acid rain."
Lomborg cites figures from the Census Bureau, International Monetary Fund, World
Bank, and European Environment Agency to show that world population growth has
sharply slowed since 1964; international debt has declined since 1984; the
inflation-adjusted price of oil is half what it was 20 years ago; and sulfur emissions and
resulting acid rain are down substantially since 1984.
In short, "The Skeptical Environmentalist" affirms and adds weight to the scientific
refutation of contemporary environmental activist claims. In the past, such activists could
at least plausibly refute the evidence by attacking the messengers as having a right-wing
axe to grind. Such cannot be said about "The Skeptical Environmentalist."
"I'm a left-wing guy," says Lomborg, "and a vegetarian because I don't want to kill animals – you can't play the "He's right-wing so he's wrong argument" with me.
