Global warming poses a serious threat to Alpine ski resorts and the regional economies that depend on them, especially in Germany, AP quoted the OECD as saying Wednesday. The Organization for Economic Cooperation and Development, which carried out a study of ski areas across the Alps, said the mountain chain was «particularly sensitive» to climate change. «Recent warming there has been roughly three times the global average,» the report said. High-resolution reconstructions show that 1994, 2000, 2002 and 2003 were the warmest years on record in 500 years, the Paris-based organization said. «Climate model projections show even greater changes in the coming decades, with less snow at low altitudes and receding glaciers and melting permafrost higher up,» it said.
