US scientists to climb Everest, collect data on climate

A team of American scientists flew to the Mount Everest region on Wednesday to study how pollution has impacted the Himalayan mountains and glaciers that 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 collecting samples and studying the ice, snow and vegetation.

In May, the team members will try to climb the 8,850 meter-high Everest, the world's tallest mountain, and its sister peak Mount Lhotse.
