Overwhelming scientific consensus on causes of climate change

A recent analysis of scientific article abstracts that took a position on climate change suggests 97% of them agreed that anthropogenic global warming (AGW) is responsible for the rise in global average temperatures. The research looked at 4,000 articles published over the past 21 years. When authors of 2,000 papers were asked to rate their own work, 97% of them agreed that their work supported the argument for human-induced climate change. A very accessible video-abstract introduces this paper.
