a new study in environmental research letters, authored by dr. james cook and colleagues, reviewed abstracts from ~12,000 research papers from 1991 - 2011 in which the authors discussed climate change or global warming. of those papers, 97% endorsed the idea that climate change is exacerbated by humans. this is stark contrast to the public perception that there is still scientific debate about the role humans play in climate change. we scientists need to work harder to convince the public that there is no scientific debate about the causes of climate change. check out the video posted on the study site in which dr. cook describes his study in more detail.
