Some subscribers to Math-Teach might be interested in a recent post "The President and the Pipeline" [Hake (2013)]. The abstract reads:
ABSTRACT: Ryan Lizza, in his "New Yorker" article "The President and the Pipeline" at <http://nyr.kr/18g0eaB> reports on the cons of the pipeline as seen by environmentalist such as James Hansen, Bill McKibben, and Tom Steyer; and the pros as seen by the Canadian government, the oil industry, and various business interests.
In "Tar Sands and Dirty Tricks," James Hansen at <http://bit.ly/1aZnA8v> lauds Lizza's article as "excellent" but points out (a) several important errors, and (b) a recent relevant article "Climate sensitivity, sea level, and atmospheric carbon dioxide" [Hansen, Sato, Russell, & Kharecha (2013) at <http://bit.ly/1aat4bO> (1.9 MB).
"Burning all fossil fuels, we conclude, would make most of the planet uninhabitable by humans, thus calling into question strategies that emphasize adaptation to climate change." ? Hansen, Sato, Russell, & Kharecha (2013)
