“Warm” ice in Everest glacier

Khumbu glacier

The Khumbu Glacier at the foot of Mount Everest is apparently even more endangered by climate change than previously assumed. British glaciologists, who measured the ice temperature of the glacier in 2017 and 2018, point to this. At three drill sites up to an altitude of about 5,200 meters near Everest base camp, they used a specified adapted car wash unit to conduct hot water under high pressure into the ice. The scientists hung strings with temperature sensors in the resulting holes, the deepest of which reached about 130 meters deep into the ice. “The temperature range we measured was warmer than we expected – and hoped – to find,” says Duncan Quincey of Leeds University, leader of the “EverDrill” project.

Climbing for climate protection

Heidi Sand

Heidi Sand knows how it is to accept a seemingly hopeless fight. “Since my cancer, I have a special relationship with probabilities and chances”, the 49-year-old German climber and sculptor write to me. “You have to believe in yourself and you should use any chance, no matter how small it is.” In 2010, Heidi was diagnosed with colon cancer at an advanced stage. She accepted the fight. Two years later, she climbed Mount Everest. In 2013, she summited Cho Oyu, her second eight-thousander. The following year, Sand and Billi Bierling were the first German women on top of Makalu. Now Heidi is committed to a climate protection project called “25zero”. During the upcoming climate summit in Paris, the Australian adventurer Tim Jarvis and his team want to point out the consequences of climate change for 25 still glaciated peaks at zero latitude, around the Equator. If nothing is done, says Jarvis, no ice or snow will remain on these mountains at the latest in 25 years – therefore “25zero”.

Dalai Lama: Climate change threatens roof of the world

It's melting away

It’s melting away

200 meters as the crow flies away from my desk, nothing less than the future of the planet is negotiated. Until Friday representatives from around the world are debating at the World Conference Center Bonn on a new climate agreement. It is to be adopted at the global climate talks in Paris, which will begin in late November. Once again the negotiations are long and tough. The solidarity with the states that are already feeling the effects of climate change is within limits. In most cases economy beats ecology. But the clock is ticking. With only a few exceptions, glaciers are melting worldwide. Glacier Works, an organization founded by US mountaineer David Breashears in 2007, has impressively documented how far for instance the glaciers around Mount Everest have retreated during the past decades. Now the Dalai Lama has pointed to the consequences of climate change for his Tibetan homeland.

When the glacier melts

Tsho Rolpa in Nepal

Tsho Rolpa in Nepal

Nepal has a problem with its glaciers. Over the past three decades, the 3808 glaciers in the Himalayan country have shrunk by about a quarter. The increased melt created some glacial lakes which scientists call ticking time bombs. One of the biggest of them, Tsho Rolpa, which is located about 100 kilometers northeast of Kathmandu, is estimated to contain between 90 and 100 million cubic meters of water by now. If the natural dam burst, it would have devastating consequences. This week, the Nepalese capital is hosting an international conference, during which more than 200 scientists from around the world exchange their findings about the impact of climate change on the high mountains of Asia – not only on the the Himalayas, but also on Karakoram, Hindu Kush, Tien Shan, Pamir and the Tibetan plateau.
