Farming practices of the Vikings and their ancestors could provide inspiration for resilient food systems today. A new study from the VIKINGS project, GEO, UiO exploring how Scandinavian societies adapted their agricultural activities in a period of European history marked by stark climate fluctuations. Read about their study in 'News by AGU'.

Ifølge norrøn mytologi skulle fimbulvinteren bli etterfulgt av ragnarok.  Klimaforskerne har nå påvist en kuldeperiode i jernalderen, trolig på grunn av to store vulkanutslipp i 536 og 540. Forskerne tilknyttet Vikings-prosjektet/UiO ser nå etter samenhenger, og hvordan kuldeperioden påvirket befolkningen i Skandinavia. Les mer i UiOs Apollon.

Historiske kilder beskriver kulde og tåke over Europa, Midt-Østen, deler av Asia. De norrøne sagaene forteller om Fimbulvinteren og at Fenrisulven hadde slukt sola. Hva skjedde året 536? Det tverrfaglige UiO-forskerteamet i VIKINGS vil finne ut om det kjølige klimaet gav uro, folkevandring og vikingtokt. Årringer i gamle trestammer gir verdifull informasjon.

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.

The Department of Geosciences has several externally financed projects, in 2017 external research support contributed 50% of the department's economy. On Monday the 27th of August there was a start-up meeting for one of the newest projects - Volcanic Eruptions and their Impacts on Climate, Environment, and Viking Society in 500-1250 CE (VIKINGS). The project is supported by FRIPRO/Toppforsk/FRINATEK.
