Some people here have disputed the existence of a scientific consensus that global warming is caused by humans. The author of the paper that found 97% of climate change scientific papers affirm that global warming is caused by humans responds to some criticisms of the paper: " In 2013, I was lead author of a scientific paper that found 97 per cent of relevant climate science papers affirm humans are causing global warming. I have to confess the level of attention our paper received took me by surprise. Our research was widely cited in scientific papers and won an award for best paper of 2013. I’d like to share three little known facts about our research. First, while the 97 per cent figure refers to the number of papers, we also counted the number of scientists who wrote those papers. We found that 98.4 per cent of the scientists who wrote papers attributing a cause to warming supported the consensus. This further demonstrates the strong agreement among the scientists. Second, our paper was not the first to find 97 per cent consensus. A 2009 study by Peter Doran at the University of Chicago, and a separate 2010 study by William Anderegg at Princeton University both found 97 per cent consensus among publishing climate scientists. Replication is at the heart of the scientific method. Three separate studies, using three independent methods, found overwhelming scientific agreement that humans are causing global warming. This brings me to the third fact about our research. We found 97 per cent consensus by reading the abstracts (or summary paragraph) of each paper. But we also invited the scientists who authored the papers to rate their own research. After all, who is more qualified to describe what a paper is saying than the scientists who wrote it? This independent method found 97 per cent of relevant papers were author-rated as endorsing the consensus."
