Physicists at ETH Zurich have developed a lens with magic properties. Ultra-thin, it can transform infrared light into visible light by halving the wavelength of incident light.
On Wednesday, the Birch Glacier collapsed under the weight of rock and debris from rockfalls on the Kleine Nesthorn. Following an on-site inspection, ETH Zurich researchers explain the background to the collapse that buried the village Blatten in an updated fact sheet.
A new study with ETH Zurich, finds that if global warming exceeds the Paris Climate Agreement targets, the non-polar glacier mass will diminish significantly. However, if warming is limited to 1.5°C, at least 54 per cent could be preserved—more than twice as much ice as in a 2.7°C scenario.
