New study warns: We have underestimated the pace at which the Arctic is melting

Arctic sea ice is melting more quickly than once assumed. Today’s climate models have yet to incorporate the steep rise in temperatures that have occurred over the past 40 years. This, according to a new study by…

New Ice Core Storage facility at the Niels Bohr Institute, University of Copenhagen. Official inauguration on 11 March

The researchers at the Niels Bohr Institute, University of Copenhagen, are world leading in climate research based on ice cores. The ice core research at the institute dates back slightly more than 50 years and takes it…

Coincidences influence the onset and ending of ice ages

An analysis of the so called climate spectrum shows why the ice ages have not behaved precisely as the models predict. A large element of coincidence is involved when an ice age begins or ends, the analysis shows. Peter…
