Global Warming Causes Changes in Swiss Insect Fauna
Research
WSL
How has the distribution of insects in Switzerland changed over the past 40 years? The range of many species has expanded, while that of a similar number has contracted. In particular, cold-adapted species have lost ground. These are the findings published in the journal Nature Communications.
Urban planning helps mitigate extreme weather effects in Haut-Valais
Teaching
EPFL
Olivier Lalancette, an EPFL Master’s student in architecture, has come up with some development proposals for the Brig-Visp-Naters conurbation. His suggestions, relatively modest in scope, could help these cities better withstand the droughts and heavy rainfall that are expected to intensify by 2050. Lalancette hopes his study will start a conversation about the region’s future.
COP27: Climate finance needs more transparency
Politics
ETH Zurich
The promise of industrialised countries to financially support emerging and developing countries in climate measures remains unfulfilled at the beginning of the climate conference in Egypt. Florian Egli explains what the states are negotiating at COP27 and what could help to alleviate the loss of trust.
Always following the sun
Research
Empa
Limiting global warming to 1.5 degrees requires the energy system to be restructured as quickly as possible. But the speed of this transformation is physically limited. An Empa study now calculates the influence of energy storage systems on the maximum possible transition speed – and thus also on the probability of successfully mastering the climate crisis.
A dry wake-up call
Research
ETH Zurich
The 2022 summer was a further illustration of how climate is becoming more extreme year after year. Sticking to business-as-usual and counting on adaptation alone will not work. Only a rapid phase out of fossil fuels will prevent the worst, says Sonia Seneviratne.  
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.
