By 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

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

Violent thunderstorms can often cause torrential rain, which poses a threat for both humans and the infrastructure. Until now such extreme weather phenomena have been very poorly understood.

Future global warming will not only depend on the amount of emissions from man-made greenhouse gasses, but will also depend on the sensitivity of the climate system and response to feedback mechanisms.

The Danish Mars researcher Jens Martin Knudsen has had an area on Mars named after him. The site has been named Knudsen Ridge and has a very beautiful location by Endeavour Crater near the equator.

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.

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
