The American Geophysical Union’s house organ, Eos, has an article entitled “Examining the Scientific Consensus on Climate Change,” written by Peter Doran and Kendall Zimmerman of the University of Illinois at Chicago. (h/t Roger Pielke, Sr.)
The paper explains that the two “primary questions” asked were:
1. When compared with pre-1800s levels, do you think that mean global temperatures have generally risen, fallen, or remained relatively constant?
2. Do you think human activity is a significant contributing factor in changing mean global temperatures?
