Surface meltwater streams cut into the ice sheet surface in Western Greenland during summer. These streams will eventually plunge to the rock bed beneath where the water can cause speed changes in the glaciers above as they slide towards the coast. DTU Space and Scientists from Université Grenoble Alpes have discovered that water can get from the surface to the bedrock even in winter when air temperatures are below the freezing point.

Lakes collapse in Greenland during winter and release meltwater to the seas

18 lakes on the ice sheet have collapsed, and the water from them is causing glaciers to slide faster towards the sea, according to new international research with contributions...

New knowledge about giant lightning bolts in space

Measurements from the large ASIM space project shows a firework of blue lightning and X-ray radiation above thunderclouds.

The ice cap is monitored via satellites combined with data from 57 GPS stations measuring directly on the bedrock in Greenland how much it rises when the ice on top of it melts away. In this way, the loss of ice is calculated very precisely.  Photo: Finn Bo Madsen.

Greenland ice melt accelerating dramatically

New study shows that the melt process reacts surprisingly quickly to changes in the atmosphere and the waters around Greenland.
