I have brought my previous study (see here and here) up-to-date by reviewing peer-reviewed articles in scientific journals over the period from Nov. 12, 2012 through December 31, 2013. I found 2,258 articles, written by a total of 9,136 authors. (Download the chart above here.) Only one article, by a single author in theHerald of the Russian Academy of Sciences, rejected man-made global warming. I discuss that article here.
My previous study, of the peer-reviewed literature from 1991 through Nov. 12, 2012, found 13,950 articles on “global warming” or “global climate change.” Of those, I judged that only 24 explicitly rejected the theory of man-made global warming. The methodology and details for the original and the new study are described here.
