Sometimes I think the climate debate remains stalled because those who are most concerned refuse to ask the pertinent questions. Instead, they keep refighting old battles that are no longer relevant to a constructive discourse. The latest example is this survey by John Cook et al that is getting a lot of undeserved attention in the mainstream media. I say that because, questionable methodology aside, the survey tells us nothing new and is, as science journalist David Appell noted, "a meaningless exercise." The main finding, which was just published in the journal Environmental Research Letters:
A new survey of over 12,000 peer-reviewed climate science papers by our citizen science team at Skeptical Science has found a 97% consensus in the peer-reviewed literature that humans are causing global warming.
