Nature Climate Change article on "Aerosols in current and future Arctic climate"

A Nature Climate Change article by scientists from École Polytechnique Fédérale de Lausanne, Switzerland, and Stockholm University, Sweden, highlights the role of aerosols in contemporary Arctic climate change. "To improve understanding of present day and future Arctic, more detailed knowledge is needed on natural Arctic aerosol emissions, their evolution and transport, and the effects on cloud microphysics."

Meager improvement for crops despite higher rainfall in the Sahel

A study by researchers at Stockholm University and Aalto University in Finland in Environmental Science Letters reveals that higher annual rainfall in the Sahel has not improved crop and vegetation conditions more than in a few places.
