Abrupt ice age climate changes behaved like cascading dominoes

Throughout the last ice age, the climate changed repeatedly and rapidly during so-called Dansgaard-Oeschger events, where Greenland temperatures rose between 5 and 16 degrees Celsius in decades.

Researchers discover intact plant fossils beneath Greenland’s ice sheet for the first time

For the first time ever, researchers have found fossils under Greenland's ice sheet that are so large and well preserved that they can be seen with the naked eye. The fossils reveal several million years of details abou…

PICE Copenhagen joins large scale joint effort in the arctic within the Danish Commonwealth

The Ministry of Higher Education and Science has awarded just below 37 million kr to a targeted effort to investigate the significance of climate change in the arctic environment.

Prominent professor named as Head of Scientific Research at Denmark’s National Centre for Climate Research

Floods, cloudbursts, heatwaves; the climate of the future will be more extreme. On assuming the position of Head of Scientific Research at the National Centre for Climate Research at DMI on 1 March 2021, renowned…

Are we alone? UCPH researchers hold their breath ahead of Mars landing

Traces of prehistoric life will be the ultimate goal as the NASA rover Perseverance lands on Mars tonight. Researchers from the University of Copenhagen have contributed several important elements to the mission.

Sea level will rise faster than previously thought

NBI researchers have constructed a new method of quantifying just how fast the sea will react to warming. The level of the sea is monitored meticulously, and we can compare the responsiveness in models with historical…

The Catcher in the Ice

A new device used to extract gas trapped in ice cores by sublimation will shave hours off the time needed by previous versions of the technology. It will use a light source with a more suitable wavelength, which will…
