Each year, Earth Day is accompanied by predictions of doom. Let’s take a look at past predictions to determine just how much confidence we can have in today’s environmentalists’ predictions.
In 1970, when Earth Day was conceived, the late George Wald, a Nobel laureate biology professor at Harvard University, predicted, “Civilization will end within 15 or 30 years unless immediate action is taken against problems facing mankind.” Also in 1970, Paul Ehrlich, a Stanford University biologist and best-selling author of “The Population Bomb,” declared that the world’s population would soon outstrip food supplies. In an article for The Progressive, he predicted, “The death rate will increase until at least 100-200 million people per year will be starving to death during the next ten years.” He gave this warning in 1969 to Britain’s Institute of Biology: “If I were a gambler, I would take even money that England will not exist in the year 2000.” On the first Earth Day, Ehrlich warned, “In 10 years, all important animal life in the sea will be extinct.” Despite such predictions, Ehrlich has won no fewer than 16 awards, including the 1990 Crafoord Prize, the Royal Swedish Academy of Sciences’ highest award.
In International Wildlife (July 1975), Nigel Calder warned, “The threat of a new ice age must now stand alongside nuclear war as a likely source of wholesale death and misery for mankind.” In Science News (1975), C.C. Wallen of the World Meteorological Organization is reported as saying, “The cooling since 1940 has been large enough and consistent enough that it will not soon be reversed.”
In 2000, climate researcher David Viner told The Independent, a British newspaper, that within “a few…
