Climate Change
First full-year study of turbulent mixing in Lake Geneva
Research
EPFL Eawag
Changing temperatures and varying winds over the seasons cause great fluctuations in Lake Geneva. The LéXPLORE research platform monitored the movement of water within the lake for a year to learn more about how natural factors influence the lake’s mixing. The resulting analysis now paints a fuller picture of mixing in large lakes, which had previously only been studied over shorter time periods.
Corona does not help climate change

The CO2-reducing effect of the pandemic has fizzled out, as the Global Carbon Project confirms in its latest report on greenhouse gas emissions. Nicolas Gruber nevertheless identifies some bright spots.
"We can now look at climate change regionally"
Research
PSI
At the beginning of August this year, a part of the sixth report of the Intergovernmental Panel on Climate Change (IPCC) was released. Chemist Margit Schwikowski, head of the Laboratory for Environmental Chemistry at PSI, contributed to this work. In an interview, she explains what aerosols have to do with climate change.
New center pools expertise to act on climate change

EPFL
The CLIMACT center brings together experts in climate change from the University of Lausanne and EPFL. Its goal is to serve as an effective interface between science and society. Presentation and interviews.
Net zero needs a plan

ETH Zurich
It will take more than a long-term target for 2050 to achieve climate neutrality, says Reto Knutti. Policymakers must take a consistent approach towards net zero, and define a reduction path with specific measures and interim targets.
Water plays a key role in reducing urban heat
Research
Eawag
Heatwaves and heavy local rainfall will increase with climate change, pushing traditional urban drainage systems to their limits. These problems can be addressed using the blue-green infrastructure approach. With careful planning, solutions of this kind can also increase biodiversity and improve the quality of urban life.
