Tracking the amount of sea ice from the Greenland ice sheet

27. september 2016

Tracking the amount of sea ice from the Greenland ice sheetBy analysing ice cores drilled from deep inside the Greenland ice sheet, researchers have started to calculate how much Arctic sea ice there was in the past. The results have just published in the research journal Scientific

Acidity in atmosphere minimised to preindustrial levels

19. september 2016

Acidity in atmosphere minimised to preindustrial levels New research shows that human pollution of the atmosphere with acid is now almost back to the level that it was before the pollution started with industrialisation in the 1930s. The results come from studies of the Greenland

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
