A Sept. 18 paper in the journal Climate Dynamics claims that the climate’s long-range sensitivity to carbon dioxide could be remarkably low.

In an Oct. 4 interview with The Epoch Times, the study’s author, Nicola Scafetta, noted that models assuming that our climate system is quite sensitive to carbon dioxide are “more alarming” than those assuming it is less sensitive.
