New type of extremely reactive substance in the atmosphere

For the first time, an entirely new class of super-reactive chemical compounds has been discovered under atmospheric conditions. Researchers from the University of Copenhagen, in close collaboration with international…

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…

Professor Staley is pursuing projects on climate change and the history of AI as well as the making of modern physics

Wildfires: When nature strikes back politically

With support from the Independent Research Fund Denmark, anthropologists will investigate how the extensive rainforest wildfires in 2019 in Amazon politically affected Brazil, Bolivia, and Peru.

Telling actual time in ancient rocks

In a new study published in Nature Communications, researchers from the University of Copenhagen apply a new technique allowing them to disentangle 500 million-years-old rocks millimeter-by-millimeter, resolving the…

Physical meeting in Copenhagen

FutureArcticLives held its first physical meeting and workshop in Copenhagen hosted by the Department of Food and Resource Economics (IFRO).

Phenomenal raw materials will get Danes to fall in love with plant-based diets

Phenomenal raw materials and ingredients are the way forward if more people are to replace meat products with plant-based alternatives and Denmark is to become a world leading producer of plant-based foods. Today, the…

Large, economic wheels must be turned to make way for green cars

Which economic levers do the politicians have to pull to move people from fossil driven cars to electrified cars? That is the main question for the GREENCAR research team at the Department of Economics.

Professor inspired by housewives and schoolchildren

Past global photosynthesis reacted quickly to more carbon in the air

Ice cores allow climate researchers to look 800,000 years back in time: atmospheric carbon acts as fertilizer, increasing biological production. The mechanism removes carbon from the air and thereby dampens the…
