The Dictionary of the Climate Debate (DCD)

Definition: Here is the key claim: 97% of climate experts agree humans are causing global warming (also see scientific consensus).

According to Andrew Dessler in Grist Magazine (November 21, 2007): "While some people claim there are lots of skeptical climate scientists out there, if you actually try to find one, you keep turning up the same two dozen or so (e.g., Singer, Lindzen, Michaels, Christy, etc., etc.). These skeptics are endlessly recycled by the denial machine, so someone not paying close attention might think there are lots of them out there -- but that's not the case."

However, skeptic senator James Inhofe's U.S. Senate Committee on Environment and Public Works has published a list of 400 scientists and academics who disagree with the consensus. Click here to find out who they are and why they disagree.

Click here for The Daily Green's (a garden-variety proponent blog) detailed analysis of who is on that list. You should note that wherever possible this analysis emphasizes connections to the fossil-fuel industry, however tenuous they might be.

2. "When examining a statistical Inference, one must look at the population from which the sample was taken.

The initial sample was 11, 944 peer reviewed climate abstracts from 1991–2011 matching the topics 'global climate change' or 'global warming'.

Let’s ignore any skewing or fallacies with the sampling. Here’s the results that the 97% consensus is based on:
66.4% of abstracts expressed no position on AGW
32.6% endorsed AGW
0.7% rejected AGW
0.3% were uncertain about the cause of global warming

Now percentages can be expressed as absolute or relative. As an absolute percentage, 32.6% have endorsed AGW.

Now for the wonderful world of relative percentages. Of the 33.6% (32.6+0.7+0.3) that expressed an opinion on AGW, 32.6% endorsed AGW. Therefore 32.6 / 33.6 = 97% endorsed AGW."
