TIME magazine warned that scientists had observed “bizarre and unpredictable weather patterns” which led them to believe the world was headed for “a global climatic upheaval.” Fluctuations in temperature, rainfall and sea ice were all described as signs of impending doom.

But the scientists interviewed by TIME weren’t talking about global warming, and the magazine wasn’t issued in the 21st century. The June 1974 report in TIME warned of a new ice age, touching off other articles in respected publications about expanding glaciers, crop failures and killer tornados.

Newsweek, for example, published its own story within a year, claiming that the evidence in support of the dire predictions “has now begun to accumulate so massively that meteorologists are hard pressed to keep up with it.” The New York Times followed in 1975, noting that “a major cooling is widely considered to be inevitable.”

For more than a century, American scientists and newspapers have been predicting catastrophic climate changes. So far, none of the climate predictions has proven true.

On Feb. 24, 1895, The New York Times warned of the next Ice Age, and in 1923, the Chicago Tribune warned that ice would soon make Canada uninhabitable. But by 1933, the same papers were warning of the greatest rise in temperatures since 1776. Reports two decades later also spoke of a spike in global temperatures. Even TIME magazine reported on global warming in 1951, just two decades before the article on a new Ice Age.

Scientists then were more likely to attribute changes in the global climate to natural forces, but today scientists refer to the warming experienced at the end of the 20th century as “anthropogenic global warming,” or that caused by man. The United Nations’ Intergovernmental Panel on Climate Change has issued successive reports that predict a rise in sea levels of 8 to 17 inches over the next century as a result of the human impact on the environment.

The cause of warming, the reports contend, is an increase in greenhouse gases—chiefly carbon dioxide—caused by the burning of fossil fuels, humanity’s primary fuel for transportation, manufacturing, cooking and heating. A warming atmosphere leads to melting sea ice and glaciers, according to the U.N.’s IPCC report.

The IPCC’s viewpoints were popularized by former Vice President Al Gore in his documentary, “An Inconvenient Truth.” Gore, however, claimed sea levels would rise by 18 to 20 feet if governments around the world failed to address CO2 emissions. His documentary, although it won an Academy Award, is now challenged by multiple sources, even by various IPCC findings.
