Yesterday, the Competitive Enterprise Institute – a front group funded by ExxonMobil and other big oil companies – launched two advertisements in response to Al Gore’s new movie, An Inconvenient Truth.
The first ad portrays global warming science as a vicious smear campaign against carbon dioxide. The ad, which despite appearances is not an SNL parody, helpfully reminds us that carbon dioxide is “essential to life” because “we breath it out.”
It’s comforting to know that this is the best global warming rejectionists can come up with. There are plenty of things that are healthy and essential in reasonable quantities but harmful in extremely large quantities. (For example, drinking a few glasses of water is beneficial. Drinking 10 gallons of water can kill you.) We need some carbon dioxide, but too much causes global warming.
The second ad repeats the “carbon dixoide is our friend” theme but adds a new wrinkle. It attempts to show that the scientific evidence for global warming is in dispute, claiming a study found “Greenland’s glaciers are growing.” (Watch the second ad HERE)
Actually, the study (by Johanessen et al.) found that there was an increase in snow accumulation on Greenland’s interior. Meanwhile, other studies show that glaciers are thinning on Greenland’s coastal regions. This is exactly what you’d expect as the earth gets warmer. The climate scientists at realclimate.org explain:
However, Johanessen et al. were not able to measure all of the coastal ranges. Indeed, the thinning of the margins and growth in the interior Greenland is an expected response to increased temperatures and more precipitation in a warmer climate. These results present no contradiction to the accelerated sliding near the coasts
Expect more of this kind of deception from the right as An Inconvient Truth hits theaters on May 24.
