Carroll Quigley, who nobody accused of being a conspiracy theorist because he was a hugely respected insider and reckoned to be Bill Clinton's mentor, revealed in his book Tragedy & Hope: A History of the World in Our Time published in the 1970s where and who devised the global warming, now climate change, hoax. The idea was to unite humanity against a common foe that they'd made up. That book, along with War and Peace, is amongst the handful I couldn't complete 'cause it was never fecking ending.
