Is there a recent poll of scientists on global warming by a qualified polling agency?

Question

Most of the poll results of scientists' opinions about global warming reported on blog sites are far out of date. Does anyone know of a more recent poll, except the one by the Cato Institute?

Answer 1

I think you are asking for something that does not exist. Gallup would not presume to poll scientists.
The issue has become so political... something real scientists are uncomfortable with.
A review of the literature is the mechanism to determine current thinking on the subject.
Found this:
"The scientific consensus is clearly expressed in the reports of the Intergovernmental Panel on Climate Change (IPCC). Created in 1988 by the World Meteorological Organization and the United Nations Environmental Programme, IPCC's purpose is to evaluate the state of climate science as a basis for informed policy action, primarily on the basis of peer-reviewed and published scientific literature (3). In its most recent assessment, IPCC states unequivocally that the consensus of scientific opinion is that Earth's climate is being affected by human activities: "Human activities ... are modifying the concentration of atmospheric constituents ... that absorb or scatter radiant energy. ... [M]ost of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas concentrations" [p. 21 in (4)]."

This is what you are looking for I think

Answer 2

9 out of 10 pollsters believe that polls are the only way to determine truth.

I'm hoping they can do a poll of people who have B.S. degrees to determine if String Theory is most likely to lead to a TOE (Theory of Everything.) Seems like this is a likely field for grant money.

Answer 3

I don't know if this constitutes a "poll", but...

They reviewed ALL 928 scientific papers that contained the word "climate change" from 1993-2003.

The number that said it was a natural change? Zero.
