If Greenland were to lose all its ice, it would add 7m to global sea level


UK scientists head to Greenland this week to trial new sensors that can be placed under its 2km-thick ice sheet.

The instruments are designed to give researchers unique information on the way glaciers slide towards the ocean.

Dubbed "Cryoeggs", the devices will report back on the behaviour of the meltwaters that run beneath the ice.

This water acts to lubricate the flow of glaciers, and in a warmer world could increase the volume of ice discharged to the ocean.

This would push up global sea levels - potentially by as much as 7m, if all the ice on Greenland were to melt.

Scientists want to understand how fast the process could unfold.
