Several cone-shaped formations and lava-like flows on the surface of Mars have puzzled scientists over years. An European research team, suggests that the formations may be after mud volcanoes. Researcher Adriano Mazzini from CEED/GEO has participated in the study, which has got much attention in the international news after the study was published.

The covid-19 pandemic lockdown gives researchers a window to study how pollution affect the climate. One of the researchers is Trude Storelvmo, Professor of meteorology at Department of Geosciences. Storelvmo has over several years done research on how aerosols and skies affect the climate. Read interview in Scientific American.

In the news: In early November we could read an article about iceflow in the Artic published on the news section for the ESA webpages. It describes the research carried out in the ICEFLOW project with Bas Altena and Andreas Max Kääb, Dept. of Geosciences.

The eruption of Mount Pinatubo in 1991 had a significant impact on climate, decreasing global mean temperature by about 0.5°C. Like the famous eruptions of Krakatau (1883) and Tambora (1815), Pinatubo is located in the tropics, which has been considered an important factor underlying its strong climate forcing. Now researchers find that explosive extratropical eruptions can have a strong impact on the climate as well.
