(USA TODAY) – Half a century ago, the tobacco industry tried to preserve its market by misleading Americans about the scientific validity of research demonstrating that smoking causes cancer. To weaken efforts to fight global warming, the "climate change denial machine," in the words of the Oxford Handbook of Climate Change and Society, has been using that same strategy. For more than 20 years it has sought to cast doubt on the science that demonstrates that the climate is changing and pollution is to blame.
Why is anyone still paying attention?
The denial lobby is using pseudo-science and cherry-picked data to present the fringe view that global warming is nothing more than what Sen. James M. Inhofe, Republican of Oklahoma, famously called "the greatest hoax ever perpetrated on the American people."
Once again it has reprised its tired — and false — arguments to debunk the premier scientific assessment of global warming, produced by the United Nations Intergovernmental Panel on Climate Change. On Sept. 27, the Nobel Peace Prize-winning organization declared with near certainty that human activity is causing the climate to change. The panel's previous assessment, issued in 2007, was only slightly less certain — 90% versus the 95% in the new report. An overwhelming majority of climate scientists endorsed it.
In short, the global warming deniers are as wrong as the smoke-blowers who said in the 1960s that a pack a day was fine. No one seriously argues today that tobacco isn't bad for you — and if they did, no one would listen. But the Marlboro Men of global warming still draw attention as they deny the consensus conclusion that burning fossil fuels in power plants, cars and factories is trapping heat in the atmosphere. They deny that this will raise sea levels, bring more violent storms, and worsen droughts and heat waves. What are they smoking?
Do we have a dog in this fight? Absolutely. We just think the debate should be about fact, not fiction. We are not trying to muzzle those who disagree with us. There will be plenty to disagree about in deciding what actions to take. But it is time to ignore false and misleading statements that mask the source's bias and scam the public.
With the new attention that the I.P.C.C. report brings to the science of global warming, in coming weeks more than a few serious news reporters may be tempted in the name of "balance" to quote the deniers, who have presented increasingly discredited messages: Global warming is not happening. Or if it is, it is not caused by carbon dioxide emissions or other human activity. Or, well, it won't have an impact — we'll be fine.
Who is saying what?
- Bob Carter, Heartland Institute: "Currently the planet is cooling." Wrong. The last decade (2000-2009) was the hottest on record; 2010 was the hottest year recorded.
- Fred Singer, Science and Environmental Policy Project: "Carbon dioxide is not a pollutant." Nope. Acting under U.S. Supreme Court direction, the U.S. Environmental Protection Agency found that CO2 is a pollutant because of the harm it causes.
- Joseph Bast, Heartland Institute: "Most scientists do not believe human activities threaten to disrupt the Earth's climate." Misleading, to say the least: 97% of climate scientists agree that humans are causing global warming.
For those who write about global warming, spreading the pronouncements of fringe "skeptics" doesn't show balance. For those who read about global warming, it equates serious climate science and evaluation of peer-reviewed reports with the declarations of individuals, most lacking academic degrees in climate research, who are often funded by those standing to profit if the United States fails to curb carbon dioxide emissions.
The attention paid to the deniers has real consequences. [more]
