Eight Botched Environmental Forecasts
A new year is around the corner, and some climate scientists and environmental activists say that means we're one step closer to a climate Armageddon. But are we really?
Predicting the weather
-- especially a decade or more in advance -- is unbelievably challenging. What's the track record of those most worried about global warming? Decades ago, what did prominent scientists think the environment would be like in 2010? FoxNews.com has compiled eight of the most egregiously mistaken predictions, and asked the predictors to reflect on what really happened.
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, interviewed by the UK Independent, March 20, 2000.
Ten years later, in December 2009, London was hit by the heaviest snowfall seen in 20 years. And just last week, a snowstorm forced Heathrow airport to shut down, stranding thousands of Christmas travelers.
A spokesman for the government-funded British Council, where Viner now works as the lead climate change expert, told FoxNews.com that climate science had improved since the prediction was made.
"Over the past decade, climate science
has moved on considerably and there is now more understanding about the impact climate change will have on weather patterns in the coming years," British Council spokesman Mark Herbert said. "However, Dr Viner believes that his general predictions are still relevant."
Herbert also pointed to another prediction from Viner in the same article, in which Viner predicted that "heavy snow would return occasionally" and that it would "probably cause chaos in 20 years time." Other scientists said "a few years" was simply too short a time frame for kids to forget what snow was.
"I'd say at some point, say 50 years from now, it might be right. If he said a few years, that was an unwise prediction," said Michael Oppenheimer, director of Princeton University's Program in Science, Technology and Environmental Policy.
Of course, Oppenheimer himself is known for controversial global warming scenarios.
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.
Oppenheimer told FoxNews.com that he was trying to illustrate one possible outcome of failing to curb emissions, not making a specific prediction. He added that the gist of his story had in fact come true, even if the events had not occurred in the U.S.
"On the whole I would stand by these predictions -- not predictions, sorry, scenarios -- as having at least in a general way actually come true," he said. "There's been extensive drought, devastating drought, in significant parts of the world. The fraction of the world that's in drought has increased over that period."
That may be in doubt, however. Data from NASA's Goddard Space Flight Center shows that precipitation -- rain and snow -- has increased slightly over the century...
