Surveys of scientists' views on climate change

From Wikipedia, the free encyclopedia

Surveys of scientists' views on climate change – with a focus on human-caused or anthropogenic global warming (AGW) – have been undertaken since the 1990s.[5] A 2016 paper (which was co-authored by Naomi Oreskes, Peter Doran, William Anderegg, Bart Verheggen, Ed Maibach, J. Stuart Carlton and John Cook, and which was based on a half a dozen independent studies by the authors) concluded that "the finding of 97% consensus [that humans are causing recent global warming] in published climate research is robust and consistent with other surveys of climate scientists and peer-reviewed studies."[6] A 2019 study found scientific consensus to be at 100%,[2] and a 2021 study found that consensus exceeded 99%.[3]

Scientific consensus on causation: Academic studies of scientific agreement on human-caused global warming among climate experts (2010–2015) reflect that the level of consensus correlates with expertise in climate science.[1] A 2019 study found scientific consensus to be at 100%,[2] and a 2021 study concluded that consensus exceeded 99%.[3] Another 2021 study found that 98.7% of climate experts indicated that the Earth is getting warmer mostly because of human activity.[4]
