Four climbers die on Everest

Shockingly four people have passed away while coming down from the summit of Mount Everest.

Many people think this is because there are too many people up the mountain at the same time. Surprisingly over 100 people tried to reach the summit on Friday and Saturday, causing delays on the route. Its thought the climbers died from exhaustion and altitude sickness. This is because it's really tough to scale the world's highest peak. The four who died were from South Korea, China, Germany and Canada.

Dangers up high...

To start with there are dangers, such as bad weather, frostbite and hypothermia — that's when your body drops to a critically low temperature. Also when you are up high there is less oxygen, so it makes it harder for your body to breath. 

Don't forget... timing is really important. The worry is that if there are too many climbers, then any delays could quickly turn into a matter of life and death.

Climbers limit...

Sir Chris Bonington, famous British mountaineer led the first ever ascent of Everest's south-west face in 1975. He thinks there should definitely be a limit on how many people climb at once. But 22-year-old climber Matthew Dieumegard-Thornton, who got to the top on Saturday, said numbers were manageable.

He called for respect between climbers: "As long as the climbers are courteous of other climbers on the mountain, everyone can work well."

The mountain's worst ever climbing season was in 1996, when 15 climbers died - eight of them in one day.
