In the wake of the BP well blowout in the Gulf of Mexico and the attempted terrorist bombing of New York’s Times Square, the broadcast media have been full of the sackcloth and ashes crowd pronouncing once more the end of the hydrocarbon era and the vital need for the U.S. to “break our oil addiction” ASAP.
Their soundbites start with a half-truth and end with a fallacy. We are told that “60 percent of U.S. energy supplies still come from oil and gas,” with the implication that (i) all of that is imported; and (ii) the pittance that we produce domestically all comes from offshore facilities.
It is true that 60 percent (actually 62.5%) of our energy comes from oil and gas. But the portion that comes from natural gas, about 24% of total U.S.…

Most impact studies seem to be showing this. It leads us to think that a little warming is not so bad. Glad I have kept my mouth shut on this issue of which I know so little.”

“I agree that the case for 2C warming [for a doubling of manmade greenhouse gas forcing in equilibrium] is pretty strong.”
– Gerald R. North to Rob Bradley, email communication, August 13, 2007.
Yesterday, the Wall Street Journal published my letter-to-the-editor rebutting Kerry Emanuel’s letter, which, in turn, was critical of his fellow MIT climatologist Richard Lindzen’s op-ed, “Climate Science in Denial.”…

Hope that the climate sensitivity—how much the global temperature rises from an increase in greenhouse gas concentrations—is far beneath what the climate models calculate it to be. When it comes to trying to use emissions cuts to achieve the 2°C goal, the cat is already out of the bag—maybe not in terms of emissions-to-date, but almost certainly so for emissions-to-come.
Such is the conclusion implicit in the recent analysis by Joeri Rogelj and colleagues published in a recent issue of Nature magazine.
Rogelj et al. did yeoman’s work in collecting all the varied (non-binding) efforts pledged by all of the various countries of the world to reduce their greenhouse gas emissions under the Copenhagen Accord that came out of last December’s big United Nations Climate Conference.…
