Abstract
Although preliminary estimates from published literature and expert surveys suggest striking agreement among climate scientists on the tenets of anthropogenic climate change (ACC), the American public expresses substantial doubt about both the anthropogenic cause and the level of scientific agreement underpinning ACC. A broad analysis of the climate scientist community itself, the distribution of credibility of dissenting researchers relative to agreeing researchers, and the level of agreement among top climate experts has not been conducted and would inform future ACC discussions.
Here, we use an extensive dataset of 1,372 climate researchers and their publication and citation data to show that (i) 97–98% of the climate researchers most actively publishing in the field support the tenets of ACC outlined by the Intergovernmental Panel on Climate Change, and (ii) the relative climate expertise and scientific prominence of the researchers unconvinced of ACC are substantially below that of the convinced researchers.


“In other words, they looked for the smartest people working in climate science using publications and citations, and found that they nearly all agreed on AGW (as in the IPCC report). Those that disagreed were the least smart.”

1. But it's a conspiracy!

Those scientist made it all up because they want... uh... to control us... or something.

It's uh... volcanoes! Yea that's it!

Didn't you read about those emails!

CO2 is natural!

:sarcasm:

2. Global 'warming'

When did this 'panel' change it's name from IPGW to IPCC?

3. When I read the First Assessment Report in 1990, they were IPCC

Afaik, they always have been.

To clarify the causation, global warming drives climate change; this distinction is often confused.
