A reservoir of meltwater the size of Ireland has been found within Greenland’s ice sheet. The reservoir may increase the melting of the inland ice in the future and provides fundamental new insights into the dynamics of the Greenland ice cap.
A new method for dating ancient sea shells reveals that the Greenland Ice Sheet was smaller between 3,000 and 5,000 years ago than it is today. The new study also indicates that the inland ice is more robust than previously thought.
The ocean floor contains viruses and bacteria locked in a constant struggle for survival. This has a great effect on the carbon cycle in the ocean and thus also affects how much CO2 is released into the atmosphere.
