In a study published this week in The Cryosphere, researchers from the National Centre for Atmospheric Science and University of Reading demonstrate how climate change could lead to irreversible sea level rise as temperatures continue to rise and the Greenland ice sheet continues to decline.
The massive ice sheet faces a point of no return, beyond which it will no longer fully regrow, permanently changing sea levels around the world.
The Greenland ice sheet is seven times the area of the UK, and stores a large amount of the Earth’s frozen water. At current rates of melting, it contributes almost 1mm to sea level per year, and accounts for around a quarter of total sea level rise.
Since 2003, despite seasonal periods of growth, Greenland’s ice sheet has lost three and a half trillion tonnes of ice.
Rising sea levels are one of the most severe effects of climate
