An aerial photo taken in December 2006 depicts a submerged village in Gaarsen, Tana River district southwest of Nairobi, Kenya. U.N. experts released a report today predicting that greenhouse gases would change rainfall patterns, intensify tropical storms, accelerate the melting of Arctic ice and mountain glaciers, amplify the risk of drought, flooding and water stress and would have a far-reaching impact on habitat and wildlife. Scientists estimate that as many as 30% of animal and plant species will be vulnerable to extinction if global temperatures rise by 2.7 to 4.5 degrees Farenheit. (Tony Karumba AFP/Getty Images)

One glacier scientists have studied for decades is retreating by about 600 feet a year. In many places, as ice disappears, so do future water supplies. Greenhouse gases are predicted to contribute to this scenario. Here, a helicopter lands on the northernmost iceberg off Dunedin. (Stephen Jaquiery AFP/Getty Images)
