1,372 climate researchers were analyzed based on their citations and publications.
98% of those in the study support the belief in anthropogenic climate change.
The 2% who didn't support the belief were found to have substantially less expertise in the area than their counterparts.
The study basically says that almost all experts agree, and the few who disagree aren't really experts comparatively. Source, from the National Academy of Sciences:

Someone mentioned
upthread that there was growing evidence against global warming. I'd sure love to see it.
