Following up on Laura's post and yesterday's New York Times article, I thought I'd throw in my two-cents regarding the recent decline in the proportion of Americans who believe in global warming.
As Laura pointed out, there is now A LOT of information available to the public about global warming and climate change. Thanks to the Internet and the recent increase in the amount of attention paid to this issue by scientists, politicians, and the media, detailed reports about the science behind global warming can easily be accessed by the average web surfer.
Unfortunately, however, the increased availability of accurate data has been accompanied by a simultaneous dissemination of DISinformation -- false or inaccurate information that is spread deliberately to influence public opinion or obscure the truth.
Princeton professor Julian Zelizer noted in the Times that "one of the main tactics of opponents of environmental regulation since the 1940s has been to challenge the science" -- such strategies are neither new nor surprising, but that doesn't excuse our complacency in allowing such propaganda. Here (as on most issues), I must agree with the late author and conservationist Douglas Adams, who wrote that "all opinions are not created equal -- some are a very great deal more robust, sophisticated and well-supported in logic and argument than others".
In the case of global warming, logic and argument are bolstered by hard science: the Intergovernmental Panel on Climate Change (IPCC), which represents the consensus of the international scientific community, has concluded that global warming IS currently taking place and is very likely caused by human activities. ["Very likely" is a technical term which denotes a greater than 90% certainty that global warming is caused by man's burning of fossil fuels.]
Yet, despite all the evidence, skepticism and uncertainty -- fueled by disinformation -- abound. For example:
- The Great Global Warming Swindle, a "documentary" that challenges the idea that global warming is man-made, is under investigation for falsifying scientific data.
- The Nongovernmental International Panel on Climate Change (NIPCC), a group that similarly insists that "nature, not human activity, rules the planet", was recently exposed for its extensive ties to (and funding from) Exxon-Mobile.
Now, the recent Harris Poll data reveal that much of the decrease in the percentage of Americans who believe in global warming (71% in 2007 vs. 51% in 2009) may be attributed to an increase in the proportion who are "not sure" (6% in 2007 vs. 21% in 2009).
So, in my opinion, the declining belief in global warming suggests not that there is too much information available, but that the wrong information is being disseminated and, more dangerously, touted and perceived as accurate.
That being said... how could we possibly decide where to draw the line? Is the risk of disinformation the price we pay for freedom of speech and freedom of press? And is it worth it?
