Extratropical volcanoes influence climate more than assumed
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.

Notes and relevance for the VIKINGS-project
This study was supported by (among others) the NFR project “VIKINGS” and by the European Union project StratoClim.
The study is a product of the Volcanic Impacts on Climate and Society (VICS) working group, as part of the Past Global Changes (PAGES) project, which in turn received support from the US National Science Foundation and the Swiss Academy of Sciences.
