Re: “Another View: Columnist’s claim of left-wing bias on climate unfounded” (June 9): I was glad to see Robert Libby’s response to M.D. Harmon’s May 23 column.

Ultimately, this relates to the assertion that “97% of scientific papers taking a stand on climate change say it is man-made.”

The following sums it all up and provides the source for readers to determine for themselves the validity of that claim.

I find it hard to believe anyone would agree with Harmon after seeing the data available at the link below.

That 97 percent consensus comes from a detailed analysis of 11,944 climate abstracts from 1991 to 2011 matching the topics “global climate change” or “global warming,” including invited input from the authors of the studies.

It’s all at this link: http://iopscience.iop.org/1748-9326/8/2/024024/article.
