“The climate change began in 1960,” the report’s first page informs us, “but no one, including the climatologists, recognised it.” Crop failures in the Soviet Union and India in the early 1960s had been attributed to standard unlucky weather. The US shipped grain to India and the Soviets killed off livestock to eat, “and premier Nikita Khrushchev was quietly deposed”.
the early 1970s saw reports of droughts, crop failures and floods from Burma, Pakistan, North Korea, Costa Rica, Honduras, Japan, Manila, Ecuador, USSR, China, India and the US. But few people seemed willing to see a pattern: “The headlines from around the world told a story still not fully understood or one we don’t want to face,” the report said.
