Apa Sherpa, the Nepali climber who has conquered Mount Everest a record 21 times, said he was disturbed by the lack of snow on the world's highest peak, caused by rising temperatures.
"In 1989 when I first climbed Everest there was a lot of snow and ice but now most of it has just become bare rock. That, as a result, is causing more rockfalls which is a danger to the climbers," he told AFP.
"Also, climbing is becoming more difficult because when you are on a mountain you can wear crampons but it's very dangerous and very slippery to walk on bare rock with crampons."
