Mount Everest and its surrounding peaks are increasingly polluted and warmer, and nearby glaciers are melting at an alarming rate that is likely to make it more dangerous for future climbers, a US scientist who spent weeks in the Everest region said Tuesday.
Prof. John All of Western Washington University said after returning from the mountains that he and his team of fellow scientists found there was lot of pollution buried deep in the snow, and that the snow was surprisingly dark when they processed and filtered it.
"What that means is there are little pieces of pollution that the snow is forming around, so the snow is actually trapping the pollution and pulling it down," All said in Kathmandu, Nepal's capital.
All and his team spent weeks testing snow on Everest and its surrounding peaks, as well as plants on the foothills.
"The warming temperature is melting the glaciers and the snow around Mount Everest very quickly, so what happens is even when there is a storm it melts in a couple of hours," he said.
"The glaciers are retreating dramatically because of global warming."
