How trees influence cloud formation
Researchers at PSI have taken a closer look at a previously disregarded factor in the formation of clouds. This could improve the accuracy of climate forecasting.
Climate-neutral air travel: Is it possible?
Above all, meeting this goal will require sustainable fuels and a reduction in air traffic.
4000 scenarios for a climate turnaround
Researchers at PSI and Columbia University are calculating in detail how climate change can be slowed down.

Consideration in future climate models important.
Rescuing Earth’s icy memory
An international research team with PSI participation is rushing to preserve glacier ice for posterity.
"We can now look at climate change regionally"
Margit Schwikowski is head of the Laboratory for Environmental Chemistry at PSI. In an interview, she explains what aerosols have to do with climate change.
‘Ice Memory Mission’ accomplished
During its expedition to the Monte Rosa massif, the international Ice Memory team extracted two ice cores over 80 meters long from Colle Gnifetti, the oldest ice in the Alps.
The glacial memory of the Monte Rosa
The next mission to preserve the climate heritage of the Pennine Alps has begun: For the Ice Memory Project, researchers set off for Monte Rosa’s Colle Gnifetti.
Aerosol formation in clouds
How chemical reactions in clouds can influence the global climate.
Particulates are more dangerous than previously thought
A precise look into the finest particles in the air shows how compounds harmful to human health are formed.
Which particulate air pollution poses the greatest health risk?
The composition of particulate matter can influence its harmfulness to human health just as much as the amount, PSI researchers show in a newly published study. Experiments and computational modelling showed that in Europe high concentrations of particulate matter harmful to human health occur mainly in metropolitan areas.
SwissFEL: a perfect habitat for the black mortar bee
For the construction of the SwissFEL facility in 2013, around five hectares of forest were cleared and transformed into a new habitat for flora and fauna. Biologists and forest engineers have now assessed the results of the renaturization project and are excited about the progress to date.
