1970s : Climate Cooling Predictions ;-) In the 1970s, we are ....told to be worried, very worried, about global cooling.... In the 2000s, we are ...told to be worried, very worried, about global warming.... -------------------------------------------------------------------------------- Washington Post's George F. Will article : "Let Cooler Heads Prevail --- The Media Heat Up Over Global Warming" washingtonpost.com Starts off: ..."So, "the debate is over." Time magazine says so. Last week's cover story exhorted readers to "Be Worried. Be Very Worried," and ABC News concurred in several stories."... 1970s: ...."told to be worried, very worried, about global cooling."... (1) Science magazine (Dec. 10, 1976) warned of "extensive Northern Hemisphere glaciation." (2) Science Digest (February 1973) reported that "the world's climatologists are agreed" that we must "prepare for the next ice age." (3) The Christian Science Monitor ("Warning: Earth's Climate is Changing Faster Than Even Experts Expect," Aug. 27, 1974) reported that glaciers "have begun to advance," "growing seasons in England and Scandinavia are getting shorter" and "the North Atlantic is cooling down about as fast as an ocean can cool." (4) Newsweek agreed ("The Cooling World," April 28, 1975) that meteorologists "are almost unanimous" that catastrophic famines might result from the global cooling... (5) New York Times (Sept. 14, 1975) said "may mark the return to another ice age." (6) The Times (May 21, 1975) also said "a major cooling of the climate is widely considered inevitable" now that it is "well established" that the Northern Hemisphere's climate "has been getting cooler since about 1950." -------------------------------------------------------------------------------- Climate Cooling Introduction: general awareness and concern en.wikipedia.org ...."In the 1970s there was increasing awareness that estimates of global temperatures showed cooling since 1945. The general public had little awareness about carbon dioxide's effects: at the time garbage, chemical disposal, smog, particulate pollution, and acid rain were the focus of the public concern, although Paul Ehrlich mentions the climate change from the greenhouse gases in 1968. However, not long after the awareness reached the public press in the mid-1970s the temperature trend stopped going down. Even by the early 1970s there was concern in the climatological community about carbon dioxide's effects, and it was known that both natural and anthropogenic effects caused variations in global climate. Currently there are some concerns about the possible cooling effects of a slowdown or shutdown of the thermohaline circulation, which might be provoked by an increase of fresh water mixing into the North Atlantic due to glacial melting. The probability of this occurring is generally considered to be low,"... ..."However, the idea intrigues the public mind and is often over-hyped; it formed the basis of the scientifically inaccurate film The Day After Tomorrow."...

The evidence shows that abrupt coolings occurred not only during the ice ages, but also during the current warmer period - long after most ice sheets disappeared and conditions on earth more closely resembled today's."... ..."The discovery of warming and cooling cycles in the modern era adds a new factor in predicting future global climate change. And it throws new light on historical events, such as the Little Ice Age, a cold spell that gripped the world several hundred years ago."... -------------------------------------------------------------------------------- Climate Cooling : impact of volcanic eruptions volcano.und.nodak.edu Symonds, Rose, Bluth, and Gerlach concluded that stratospheric injection of sulfur dioxide (SO2) is the principal atmospheric and global impact of volcanic eruptions. -------------------------------------------------------------------------------- PONDERING A CLIMATE CONUNDRUM IN ANTARCTICA January 13, 2002 : Antarctica's freeze puzzles scientists huey.colorado.edu ..."Unique, distinct cooling trend discovered on Earth's southernmost continent Antarctica overall has cooled measurably during the last 35 years - despite a global average increase in air temperature of 0.06 degrees Celsius during the 20th century - making it unique among the Earth's continental landmasses, according to a paper published today in the online version of Nature."... ..."The findings are puzzling because many climate models indicate that the Polar regions should serve as bellwethers for any global warming trend, responding first and most rapidly to an increase in temperatures. An ice sheet many kilometers thick in places perpetually covers almost all of Antarctica. Temperature anomalies also exist in Greenland, the largest ice sheet in the Northern Hemisphere, with cooling in the interior concurrent with warming at the coast."...
