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…

Sources of doubt: actors, forums, and language of climate change skepticism

The paper investigates the reference corpus of a climate change contrarian report and categorized the journal abstracts according to the endorsement positions on anthropogenic climate change, and showed moderate differences in the endorsement rates as well as in the sources of contrarian arguments considering the contrarians report in general and the presented journals specifically.
