Tens of thousands of hand calculations lead Arrhenius to the conclusion that the Earth\u2019s temperature might increase by 5 to 6 degrees Celsius with a doubling of atmospheric CO<sub>2<\/sub>. He suggests that this increase could make the Earth\u2019s climate \u201cmore equable,\u201d stimulating plant growth and food production. He also errs in his timescale, believing it would take humans 3,000 years to double atmospheric CO<sub>2<\/sub>.<sup>*<\/sup> A 1912 issue of Popular Mechanics brought the work of Arrhenius to the attention of the general public: \u201ca theory has been elaborated, primarily by the great Swedish scientist Arrhenius, that the earth has had a warm climate when the carbon dioxide in the atmosphere was abundant, and a cold climate when it was scarce.\u00a0 It is believed that if the atmosphere contained two to three times its present amount, the climate would be considerably warmer.\u201d Under a photo of massive plumes of smoke coming from factory smokestacks, the article elaborates, \u201cThe furnaces of the world are now burning about 2,000,000,000 tons of coal a year. When this is burned, uniting with oxygen, it adds about 7,000,000,000 tons of carbon dioxide to the atmosphere yearly. This tends to make the atmosphere a more effective blanket for the earth and to raise its temperature. The effect may be considerable in a few centuries.\u201d<sup>**<\/sup><\/p>\n<p class=\"footnote-body\"><sup>*<\/sup>Svante Arrhenius, \u201cOn the influence of carbonic acid in the air upon the temperature of the ground,\u201d <em>Philosophical Magazine Series 5, <\/em>Vol. 41, Issue 251, 1896, <a href=\"http:\/\/www.tandfonline.com\/doi\/abs\/10.1080\/14786449608620846\" target=\"_blank\" rel=\"noopener noreferrer\">www.tandfonline.com<\/a>; Richard Wolfson, <em>Energy, Environment, and Climate<\/em> (New York: W.W.\u00a0 Norton, 2012) , 336.<br \/>\n<sup>**<\/sup>Page of 1912 issue of Popular Mechanics, circulated in a tweet by climate scientist Peter Gleick, June 9, 2017.
