British climber Daniel Paterson and his guide, Pastenji Sherpa, are missing on Mount Everest after being caught in an icefall during their descent from the summit.

The chances of survival in the Death Zone above 7000 meters are slim, with ongoing search efforts by local authorities.

This climbing season has seen over 570 climbers successfully reaching the summit, but also tragic deaths and disappearances.

Paterson's family has launched a fundraising appeal and established a crowdfunding campaign to support the search efforts.

Recent achievements on Everest include a new female record for the fastest ascent in 14 hours and 31 minutes, highlighting the skill and determination required to climb the mountain.

Concerns over crowding and littering on Everest have led to calls for reducing the number of climbing permits to mitigate the environmental impact.
