Rounded stones on Mars evidence of flowing water

Observations by NASA's Mars rover Curiosity have revealed areas with gravel and pebbles that are characteristic of a former riverbed. Researchers, including members of the Niels Bohr Institute, have analysed their...

Today's global warming follows more than 1000 years of colder climates

A new international study of past climate shows that the global temperature was getting colder and colder for more than 1000 years until the year 1900, after which global warming raised the temperature significantly in…

Significant contribution to sea-level rise

Glaciers at the edge of Greenland which are not connected to its huge ice sheet, or can be clearly separated from it, are contributing to sea-level rise much more than previously thought.

More hurricane surges in the future

How many extreme storm surges like that from Hurricane Katrina, which hit the U.S. coast in 2005, will there be as a result of global warming? New research from the Niels Bohr Institute show that there will be a tenfold…

Greenland ice cores reveal warm climate of the past

New research from the NEEM ice core drilling project in Greenland shows that the warm Eemian period - 130,000 and 115,000 years ago was warmer than previously thought.
