We analyze the evolution of the scientific consensus on anthropogenic global warming (AGW) in the peer-reviewed scientific literature, examining 11 944 climate abstracts from 1991–2011 matching the topics ‘global climate change’ or ‘global warming’. We find that 66.4% of abstracts expressed no position on AGW, 32.6% endorsed AGW, 0.7% rejected AGW and 0.3% were uncertain about the cause of global warming. Among abstracts expressing a position on AGW, 97.1% endorsed the consensus position that… 

Consensus on consensus: a synthesis of consensus estimates on human-caused global warming

The consensus that humans are causing recent global warming is shared by 90%–100% of publishing climate scientists according to six independent studies by co-authors of this paper. Those results are

Comment on ‘Quantifying the consensus on anthropogenic global warming in the scientific literature’

Cook et al’s highly influential consensus study (2013 Environ. Res. Lett. 8 024024) finds different results than previous studies in the consensus literature. It omits tests for systematic

Comment on ‘Quantifying the consensus on anthropogenic global warming in the scientific literature’

I read the study by Cook et al with great interest [1]. The study used levels of endorsement of global warming as outlined in their table 2; however, I could see nomention as to how these levels were

The climate change consensus extends beyond climate scientists

The existence of anthropogenic climate change remains a public controversy despite the consensus among climate scientists. The controversy may be fed by the existence of scientists from other
