White Christmases Are Doomed!

Global warming is making it less likely there will be a white Christmas.

ERLIN (Reuters) - The odds of a "white Christmas" in temperate parts of the northern hemisphere have diminished in the last century due to climate change and will likely decline further by 2100, climate and meteorology experts said.

Even though heavy snow this year will guarantee a white Christmas in many parts of Asia, Europe and North America, an 0.7-degree Celsius (1.3 Fahrenheit) rise in world temperatures since 1900 and projected bigger rises by 2100 suggest an inexorable trend.

"The probability of snow on the ground at Christmas is already lower than it was even 50 years ago but it will become an even greater rarity many places by the latter half of the century," said Friedrich-Wilhelm Gerstengarber, climate researcher at the Potsdam Institute for Climate Impact Research. In the northern German city of Berlin, for instance, the chances of snow on the ground on December 24, 25 and 26 have fallen from 20 percent a century ago to approximately 15 percent in 2008, he said. By 2100 the odds will be less than 5 percent.
