Tracking the amount of sea ice from the Greenland ice sheet

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…

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…

Congratulations to Corentin Reutenauer

Congratulations to Corentin Reutenauer who successfully defended his PhD thesis at Centre for Ice and Climate on August 23, 2016

Researchers unravel process for the formation of rainstorms

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.

Warning from the past: Future global warming could be even warmer

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.

Congratulations to Rasmus Anker Pedersen

Congratulations to Rasmus Anker Pedersen at Centre for Ice and Climate who succesfully defended his PhD thesis on Monday, June 20, 2016 and obtained the degree of Doctor of Philosophy.

Site on Mars named after Mars researcher Jens Martin Knudsen

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.

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
