Danish astrophysics student discovers link between global warming and locally unstable weather

A Danish astrophysics student at the Niels Bohr Institute has used a mathematical approach to unveil how global temperature increase engenders locally unstable weather on Earth.

New measurements from Northern Sweden show less methane emissions than feared

It is widely understood that thawing permafrost can lead to significant amounts of methane being released. However, new research shows that in some areas, this release of methane could be a tenth of the amount predicted…

Dorthe Dahl-Jensen awarded Hans Egede Medal

On Wednesday, ice core researcher Dorthe Dahl-Jensen was awarded the Hans Egede Medal for her research into Earth’s climate history. Her research has included longer stays on Greenland's deserted ice sheet and offers a…
