Apa Sherpa says that he "climbs Everest for fun"

A Nepalese man - who has been nicknamed Super Sherpa - has broken his own world record, climbing Mount Everest for the 19th time.

Apa Sherpa, 49, first made it to the summit 19 years ago.

He said his latest climb was to raise awareness of the impact of global warming on the Himalayas.

Apa Sherpa's expedition team has been collecting rubbish from the mountain as part of a campaign to return it to its pristine condition.

Apa Sherpa spent around 30 minutes at the top of Everest, unfurling a banner saying "Stop Climate Change".

Dawa Steven Sherpa, expedition team leader, told the AFP news agency: "We are very excited and happy with Apa's achievement. It will highlight the effects of global warming on Everest.

"Climbing Everest is getting more difficult and dangerous every year because of the melting ice. The rocks that used to be covered by snows are getting exposed.

"We have brought down over five tonnes of mountain trash including parts of a crashed helicopter, old ropes and tents, ladders, metal cans and climbing gear."

Veteran British adventurer Sir Ranulph Fiennes also reached the summit, succeeding after two previous attempts ended in failure.
