Peter Doran and Maggie Zimmermans Examining the Consensus on Climate Change (EOS, January 2009), concluded, It seems that the debate on the authenticity of global warming and the role played by human activity is largely nonexistent among those who understand the nuances and scientific basis of long-term climate processes. However, Doran and Zimmerman counted only 79 out of the 3,146 responses to their survey in determining the alleged consensus, and the two questions asked in the survey were framed such that even the most ardent skepticslike Fred Singer, Richard Lindzen, and Roy Spencerwould have answered Yes: Another study, Expert credibility in climate change (PNAS, April 9, 2010), by William Anderegg et al., reported that a survey of publication and citation data of 1,372 climate researchers found that 97 to 98 percent believed that anthropogenic greenhouse gases have been responsible for most of the unequivocal warming of the Earths average global temperature over the second half of the 20th century. But Andereggs study covered only the 200 most prolific writers on climate change, excluding thousands of others, and even the conclusion that humans caused most of the warming doesnt mean that those scientists consider global warming a crisis or that we should spend trillions of dollars attempting to stop it.

Given the importance of the scientific consensus on human-caused global warming in peoples' decisions whether to support action to reduce greenhouse gas emissions, and the public lack of awareness of the consensus, we need to make people aware of these results. October 28, 2018 Very few Americans are aware that 97% of climate scientists agree climate change is real long-term weather patterns and perform research that explores the overarching consequences of carbon emissions on the climate. But another scholar, Jos Duarte, did look at the selection process and found it multiply fraudulent.
