Rising sea levels of 1.8 meters in worst-case scenario

13. oktober 2014

Rising sea levels of 1.8 meters in worst-case scenarioThe climate is getting warmer, the ice sheets are melting and sea levels are rising – but how much?  Now researchers from the Niels Bohr Institute and their colleagues have calculated the risk for a worst-case scenario. The results indicate that

New insights into gamma-ray Burst afterglows

30. april 2014

New insights into gamma-ray Burst afterglowsGamma-ray bursts are powerful bursts of gamma radiation in connection with the explosive death of massive stars. The bursts themselves are short lived – typically less than a few minutes, but is followed by an afterglow that can be
