Heat and drought threaten the truffle harvest
Research
WSL
The truffle yield in Switzerland and southern Germany is declining. This is shown by a monitoring programme led by the Swiss Federal Institute for Forest, Snow and Landscape Research WSL. The increase in extremely hot and dry summers best explains this decline. This is not only a culinary problem, but also an ecological one.
Climate change made the 2022 summer droughts more likely
Research
ETH Zurich
High temperatures, fuelled by climate change, dried out soils across Europe and the Northern Hemisphere this summer, finds a team of climate scientists led by ETH Zurich in the name of the World Weather Attribution group.
Alpine plants respond to climate change
Research
ETH Zurich
Researchers from ETH Zurich are studying how alpine vegetation is responding to a warming climate – and how some plant communities are continuing to stand firm against newcomers from lower elevations.
“Carbon dioxide can be turned into a valuable resource”
Research
ETH Board
The Swiss energy system is expected to be climate-neutral by 2050. The key to this is science: CO2 can be converted by electrolysis into raw materials for chemicals or synthetic fuels and the cost of a fossil-free energy system can be calculated using modelling.
A warm intrusion in the Arctic causes extreme pollution levels
Research
EPFL PSI
During the MOSAiC research expedition, conducted in the Arctic pack ice between 2019 and 2020, EPFL and PSI scientists observed an atmospheric perturbation triggered by the intrusion of a highly polluted warm air-mass. A first study providing further insight into the phenomenon and its potential implications has just been published.
Determining the rate and shape of Arctic Greening
Research
ETH Zurich
A team of researchers from ETH Zurich and WSL travelled to Svalbard this summer to take a closer look at the phenomenon of Arctic greening. Lead principal investigator Sebastian Doetterl discusses research in the face of polar bears, airline strikes and war.
