Massive volcanic eruption puts past climate and people in perspective

05 November 2012

The largest volcanic eruption on Earth in the past millions of years took place in Indonesia 74,000 years ago and researchers from the Niels Bohr Institute can now link the colossal eruption with the global climate

Turbulent flows in 2D can be calculated in new model

23 October 2012

Turbulent flows have challenged researchers for centuries. It is impossible to predict chaotic weather more than a week in advance. Now, however, researchers from NBI have succeeded in developing a

Tropical cyclones are occurring more frequently than before

16 October 2012

Are there more tropical cyclones now than in the past? New research from the Niels Bohr Institute clearly shows that there is an increasing tendency for cyclones when the climate is warmer

Methane emissions can be traced back to Roman times

03 October 2012

Emissions of the greenhouse gas methane into the atmosphere can be traced back thousands of years in the Greenland ice sheet. The results go all the way back to Roman times and up to the present

The Mars rover Curiosity finds an old riverbed on Mars

01 October 2012

The rover Curiosity, which landed on Mars on the 6th of August, has found deposits formed in the Martian past by a fast moving stream of water with a depth between ankle and hip height

Mars's dramatic climate variations are driven by the Sun

06 September 2012

Researchers from NBI have related the layers in the ice cap on Mars’s north pole to variations in solar insolation on Mars, thus established the first dated climate history for Mars

Warming and melting on top of the Greenland ice sheet

03 August 2012

On top of the approximately 3 km thick ice sheet in Greenland the temperature is normally around minus 10-15 degrees C in the summer. This year, researchers from NBI observed temperatures above zero

Rise in temperatures and CO2 follow each other closely in climate change

23 July 2012

Rise in temperatures and CO2 follow each other closely in climate change New research from the Niels Bohr Institute indicates that, contrary to previous opinion, the rise in temperature and the rise in the atmospheric CO2 follow each other closely in terms of time.
