Methane emissions traced back to Roman times

Emissions of the greenhouse gas methane into the atmosphere can be traced back thousands of years in the Greenland ice sheet. Using special analytical methods, researchers from the Niels Bohr Institute, among others, have ...

Mars's dramatic climate variations are driven by the Sun

On Mars's poles there are ice caps of ice and dust with layers that reflect to past climate variations on Mars. Researchers from the Niels Bohr Institute have related the layers in the ice cap on Mars's north pole to variations ...
