Insulating layer of air above the Greenland ice sheet reduces precipitation

The Earth’s climate has been warming, but even though the Greenland ice sheet is melting rapidly in the coastal regions, there are large parts of the ice sheet where there has hardly been any melting on the surface.

Climate variations analysed 5 million years back in time

When we talk about climate change today, we have to recognise the natural variations to be able to distinguish them from the human-induced changes. Researchers from the NBI have analysed the natural climate variations…

Very high silicon content surprises Mars researchers

New results from the Mars rover Curosity show that some rocks in Gale Crater have a high content of the element silicon. Since the accumulation of silica typically require a combination of both heat and water, this plac…

The past shows how abrupt climate shifts affect Earth

New research shows how past abrupt climatic changes in the North Atlantic propagated globally. The study, led by researchers from The Niels Bohr Institute, shows how interaction between heat transport in the ocean and…

The Greenland ice sheet contains nutrients from precipitation

New research shows that the ice sheet on Greenland contains the nutrient phosphorus, which was carried by the atmosphere across the country, where it fell with precipitation. This new knowledge is important for...

Volcanic eruptions are important for world climate

Large volcanic eruptions release huge clouds of ash and acid into the atmosphere. These clouds spread across the globe and block out the Sun, resulting in a colder climate for decades afterwards. Climate researchers hav…

Risk of major sea level rise in Northern Europe

Global warming leads to the ice sheets on land melting and flowing into the sea, which consequently rises. New calculations by researchers from the Niels Bohr Institute show that the sea level in Northern Europe may ris…

New Greenland ice core drilled through the Renland ice cap

An international research team led by the Niels Bohr Institute at the University of Copenhagen have drilled an ice core through the ice cap on the Renland peninsula in the Scoresbysund fjord in Eastern Greenland in…

Research station moved nearly 500 km across the Greenland ice sheet

The entire research station NEEM has been moved 465 km across the Greenland ice sheet on skis to the new camp EGRIP, where there will be a future international drilling camp and a gateway to research programmes in East

Mars has belts of glaciers consisting of frozen water

Mars has distinct polar ice caps, but Mars also has belts of glaciers at its central latitudes in both the southern and northern hemispheres. A thick layer of dust covers the glaciers, so they appear as surface of the…

A.P. Møller Foundation donates 25 million kroner to ice core research

Professor Dorthe Dahl-Jensen, head of the Centre for Ice and Climate at NBIhas received a grant of 25 million kroner from the A.P. Møller Foundation for a major new research project in Greenland.

Rising sea levels of 1.8 meters in worst-case scenario

The climate is getting warmer, the ice sheets are melting and sea levels are rising – but how much? Now researchers from the Niels Bohr Institute and their colleagues have calculated the risk for a worst-case scenario.…
