The Myth of the Global Cooling Consensus
Posted by Ross Pomeroy January 13, 2014
"Contrary to what Crichton, Dobbs, and others might assert, climate scientists never agreed that the Earth was destined for long-term cooling back in the 1970s. Yes, the Earth cooled between 1940 and 1970, but it was exceedingly slight. Scientists now agree that the cooling resulted from excessive use of sulfur-based aerosols. Aerosols only remain in the atmosphere for a short period of time compared to other greenhouse gases, so the aerosol cooling effect faded away as atmospheric carbon dioxide concentrations rose. Knowing this, the majority of climate scientists at the time still anticipated warming. A review of climate change literature between 1965 and 1979, undertaken in 2008, found that 44 papers "predicted, implied, or provided supporting evidence" for global warming, while only seven did so for global cooling.
"Global cooling was never more than a minor aspect of the scientific climate change literature of the era, let alone the scientific consensus..." the reviewers remarked.
Today, the myth of the 1970s global cooling consensus lives on through blanket statements, often cited back to cherry-picked news media coverage from the time."
