KATHMANDU, Nepal (AP) — A team of American scientists has flown to the Mount Everest region to study how pollution has impacted the Himalayan mountains and glaciers which are melting due to global warming.

The team led by John All of Western Washington University plans to spend the next two months in the region and climb the world's highest peak in May while they collect samples and study the ice, snow and vegetation.
