[quote=New_Yorker]The National Academy of Sciences undertook its first rigorous study of global warming in 1979. Mentions studies by Syukuro Manabe and James Hansen. The Ad Hoc Study Group on Carbon Dioxide and Climate, headed by Jule Charney, found that if carbon dioxide emissions continued to increase, the climate changes would be severe. It’s now 25 years since that report was issued, and, in that period, carbon-dioxide emissions have increased from 5 billion a year to 7 billion, and the earth’s temperature has steadily risen. The world is now warmer than it has been at any point in the last 2 millennia.[quote]
