(CNN) Mount Everest expedition operators are finding increasing numbers of climbers' dead bodies on the world's highest peak as high temperatures melt glaciers and snow.

More than 200 mountaineers have died on the peak since 1922, when the first climbers' deaths on Everest were recorded. The majority of bodies are believed to have remained buried under glaciers or snow.

"Due to the impact of climate change and global warming, snow and glaciers are fast melting and dead bodies are increasingly being exposed and discovered by climbers," Ang Tshering Sherpa, former president of Nepal Mountaineering Association, told CNN.

"Since 2008 my own company has brought down seven dead bodies of some mountaineers, some dating back to a British expedition in the 1970s."
