How scientists installed world’s highest weather station on Everest

A dangerous trip almost ended in disaster but the project was saved with some ingenuity

What is the weather like up on Mount Everest today? Last year a bunch of daredevil scientists and Sherpas laboured in the death zone" and installed the world's highest weather station, perched at 8,430 metres, just 400 metres short of Everest's summit. But it nearly didn't happen.

Having been stuck behind a queue of climbers heading for the summit, the 2019 National Geographic and Rolex expedition team were dangerously cold when they reached the location where the station was to be installed. We paced back and forth, attempting to stave off frostbite as wind-chill temperatures hovered close to -30C and our drill batteries became too cold to work," said Loughborough University's Tom Matthews on the Conversation. Luckily team member Phutasi Sherpa had enough body heat to warm up the batteries and get the drill going again, enabling the team to bolt their weather station to the side of the mountain.
