Revkin in a 1985 global cooling (nuclear winter) scare story: "[In 1815] crops failed across both continents--and that was the result of a drop in average temperature of only 1.8 degrees Fahrenheit"

My first cover story on a potentially harmful human influence on climate ('85) was not about global warming. http://www.slideshare.net/Revkin/hard-facts-about-nuclear-winter-1985 …

The article features a quote that suggests that global cooling could cause the extinction of Homo Sapiens.  It features another quote from Bob Cess at Stony Brook that suggests that nuclear winter would be like "hitting the climate over the head with a sledgehammer" while the "almost imperceptible buildup of carbon dioxide" is "just barely tweaking" the climate.

Revkin says this about the year 1815, "the year without a summer":   "Crops failed across both continents--and that was the result of a drop in average temperature of only 1.8 degrees Fahrenheit".
