Gallup Poll

Partisanship and Disinformation Surrounding Global Warming Taking their Toll

A new Gallup poll shows that compared to three years ago, twice as many Americans believe that global warming’s consequences are exaggerated.

And in just the last year, there has been an increase in skepticism from 41% to 48%.

The chart below shows a number of trends. Skepticism about global warming was generally low in 1997, when the polling started, before climate change was getting regular news coverage, either fact or opinion based.

In fact, the level of skepticism did not change much with the increasing coverage of climate change in the wake of An Inconvenient Truth, increasingly publicized consensus among the vast majority of climate scientists that global warming was real, human caused and potentially devastating, the Third Assessment Report from the Intergovernmental Panel on Climate Change (IPCC) in 2001, or even the Nobel prize winning Fourth IPCC Assessment Report in 2007. So, we could assume that roughly 30% of the skeptics are not going to be persuaded by science. They have their opinion and they are sticking to it.
