Under climate change, back-to-back heat extremes threaten food production in Europe and the US, but most losses can be avoided by limiting global warming to 1.5 °C, according to a study led by ETH Zurich.
Glacial melting in Switzerland was once again enormous in 2025. A winter with low snow depth combined with heat waves in June and August led to a loss of three per cent of the glacier volume. This is the fourth largest level of shrinkage since measurements began. Consequently, the ice mass reduced by one quarter in the last ten years. This was reported by the Swiss Glacier Monitoring Network (GLAMOS), which is based at ETH Zurich and the Universities of Fribourg and Zurich.
New findings explain why treatment for this arterial occlusive disease often fails to produce the desired results: the problem of vascular disease lies not only in the main arteries of the legs, but also in the smallest blood vessels and surrounding muscle cells.
