The world's greatest snow-capped peaks, which run in a chain from the Himalayas to Tian Shan on the border of China and Kyrgyzstan, have lost no ice over the last decade, new research shows.
The discovery has stunned scientists, who had believed that around 50bn tonnes of meltwater were being shed each year and not being replaced by new snowfall.
The study is the first to survey all the world's icecaps and glaciers and was made possible by the use of satellite data. Overall, the contribution of melting ice outside the two largest caps – Greenland and Antarctica – is much less than previously estimated, with the lack of ice loss in the Himalayas and the other high peaks of Asia responsible for most of the discrepancy.
Bristol University glaciologist Prof Jonathan Bamber, who was not part of the research team, said: "The very unexpected result was the negligible mass loss from high mountain Asia, which is not significantly different from zero."
Emily in Der Spiegel: "Never mind!"
Vahrenholt: In my experience as an energy expert, I learned that the Intergovernmental Panel on Climate Change (IPCC) is more of a political than a scientific body. As a rapporteur on renewable energy, I witnessed how thin the factual basis is for predictions that are made at the IPCC. In one case, a Greenpeace activist's absurd claim that 80 percent of the world's energy supply could soon be coming from renewable sources was assumed without scrutiny. This prompted me to examine the IPCC report more carefully.
SPIEGEL: And what was your conclusion?
Vahrenholt: The long version of the IPCC report does mention natural causes of climate change, like the sun and oscillating ocean currents. But they no longer appear in the summary for politicians. They were simply edited out. To this day, many decision-makers don't know that new studies have seriously questioned the dominance of CO2. CO2 alone will never cause a warming of more than 2 degrees Celsius (3.6 degrees Fahrenheit) by the end of the century. Only with the help of supposed amplification effects, especially water vapor, do the computers arrive at a drastic temperature increase. I say that global warming will remain below two degrees by the end of the century. This is an eminently political message, but it's also good news.
It's a shame that neither politicians nor "journalists" understand that "climate models" are just software, and by the very nature of trying to simulate a massive, chaotic system with vast numbers of unknown variables, software that has to include massive simplifying assumptions.
