Climate science: Greenland ice sheet to contribute over 270mm to sea-level rise
Nature Climate Change The overall loss of ice from the Greenland ice sheet — alongside increasing precipitation, ice flow discharge and meltwater runoff — will lead to at least 274 mm in sea-level rise, regardless of future climate warming projections, according to a study published in Nature Climate Change.

However, despite its importance to future sea-level rise, the ability to accurately predict Greenland’s response to climate change is hindered by the imprecise measurements of land, atmosphere and ocean boundaries in current models.
