Insulating layer of air above the Greenland ice sheet reduces precipitation

29. april 2016

Isolerende luftlag over Grønlands iskappe mindsker nedbørThe 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.

Easter can be calculated with greater accuracy using new ‘old’ astronomical method

18. marts 2016

Easter can fall early and late, in fact, the timing can fluctuate by an entire month from late March to late April. Using a new astronomical method of calculation, the date of Easter would be better defined as the first Sunday after

Climate variations analysed 5 million years back in time

16. marts 2016

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 over

The Greenland ice sheet contains nutrients from precipitation

04. november 2015

The Greenland ice sheet contains nutrients from precipitationNew 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...
