Why We Avoid Making Forecasts

This is from the FOX News article, "Eight Botched Environmental Forecasts":

1. Within a few years "children just aren't going to know what snow is." Snowfall will be "a very rare and exciting event." Dr. David Viner, senior research scientist at the climatic research unit (CRU) of the University of East Anglia [the same university implicated in Climategate], interviewed by the UK Independent, March 20, 2000.

2. "[By] 1995, the greenhouse effect would be desolating the heartlands of North America and Eurasia with horrific drought, causing crop failures and food riots…[By 1996] The Platte River of Nebraska would be dry, while a continent-wide black blizzard of prairie topsoil will stop traffic on interstates, strip paint from houses and shut down computers." Michael Oppenheimer, published in "Dead Heat," St. Martin's Press, 1990.

3. "Arctic specialist Bernt Balchen says a general warming trend over the North Pole is melting the polar ice cap and may produce an ice-free Arctic Ocean by the year 2000." Christian Science Monitor, June 8, 1972.

4. "Using computer models, researchers concluded that global warming would raise average annual temperatures nationwide two degrees by 2010." Associated Press, May 15, 1989.

5. "By 1985, air pollution will have reduced the amount of sunlight reaching earth by one half." Life magazine, January 1970.

6. "If present trends continue, the world will be ... eleven degrees colder by the year 2000. This is about twice what it would take to put us in an ice age." Kenneth E.F. Watt, in "Earth Day," 1970.

7. "By the year 2000 the United Kingdom will be simply a small group of impoverished islands, inhabited by some 70 million hungry people ... If I were a gambler, I would take even money that England will not exist in the year 2000." Ehrlich, Speech at British Institute For Biology, September 1971.

8. "In ten years all important animal life in the sea will be extinct. Large areas of coastline will have to be evacuated because of the stench of dead fish." Ehrlich, speech during Earth Day, 1970
