Removal of snow cover inhibits growth of Arctic ice algae

Forecasts suggest that an important effect of climate change in the Arctic will be less snow covering sea ice. Associate Professors Lars Chresten Lund-Hansen and Brian Sorrell, Institute for Bioscience and Arctic Research Centre (ARC), and their colleagues have been studying how this affects algae living at the bottom of sea ice, which are…

Drones to map arctic vegetation

The Arctic is one of the places on earth where vegetation is expected to change most significantly during the next hundred years in consequence of increasing temperatures. Among other changes, researchers expect more shrubs to appear on the Arctic tundra.

Assistant professor Nicolaj Krog Larsen from Department of Geoscience and the Arctic Research Center (to the left) gathers sediment cores from lakes close to the edge of the inland ice to study how the inland ice reacted to climate changes earlier in the history of the world.

Bedrock and lake sediment tell the story of melting ice

Associate professor Nicolaj Krog Larsen from Department of Geoscience and the Arctic Research Center has just been granted DKK 7.0 million from VILLUM FONDEN. The grant will be used for a large-scale research project investigating how the inland ice has reacted to natural climate variations in North-East Greenland during the past 10,000 years.

Pris for forskning i vegetationsændringer i tid og rum

Signe Normand, ph.d. og adjunkt på Institut for Bioscience, Aarhus Universitet modtager i dag L’Oréals og UNESCO’s For Women in Science-prisen for sin forskning i vegetationsændringer i tid og rum – fra lokale observationer til stor-skala mønstre og modeller af ændringer på tværs af Europa og arktiske egne samt over 1.000-vis af år fra den sidste…

Ny bog viser 80 års klimaændringer set fra luften

En ny bog med flotte før-og-nu billeder fra Grønland viser, hvordan gletscherne og Indlandsisen har forandret sig i de forgangne 80 år. Bogen "Indlandsisen - 80 års klimaændringer set fra luften" er blevet til med deltagelse fra blandt andre geolog Nicolaj Krog Larsen fra Aarhus Universitet.

Geese at the water’s edge. When the European tidal marshes disappear, less food will be available to pale-bellied brent goose and other waterbirds. This poses an increasing threat to several species (Photo: Kevin K. Clausen).

Migrating birds. Brent goose and other birds breeding in the arctic migrate up to 3,000 kilometres nonstop to reach their breeding grounds in the north. This requires plenty of food and energy (Photo: Kevin K. Clausen).

Brent goose under threat by climate change

Plant-eating coastal birds are under threat. Tidal marshes are no longer managed through natural grazing, and rising temperatures lead to increasing water levels. The life-giving tidal marshes are shrinking drastically in area from year to year. Consequently, less food and energy are available to migratory birds before flight northward to their…

Global opvarmning gør kloden mere og mere grøn

Forskere fra Aarhus Universitet har bl.a. studeret satellitbilleder og ser tydeligt, at Jorden generelt er i gang med at blive grønnere. Især på de nordlige egne breder buske og træer sig på tundraen. Allerede i dag er der områder på den nordlige halvkugle, hvor vegetationen i dag ligner den, der for 30 år siden lå fire-seks grader længere sydpå…
