Greenland ice cap melt inevitable sea levels may rise 27cm

31 August 2022

We’re passed the time for warnings… a significant increase in sea levels is unavoidable, with the melting of the Greenland ice cap expected to add twenty-seven centimetres to global ocean tidemarks. It could be a whole lot more if (or when) other ice masses melt:

Major sea-level rise from the melting of the Greenland ice cap is now inevitable, scientists have found, even if the fossil fuel burning that is driving the climate crisis were to end overnight. The research shows the global heating to date will cause an absolute minimum sea-level rise of 27cm (10.6in) from Greenland alone as 110tn tonnes of ice melt. With continued carbon emissions, the melting of other ice caps and thermal expansion of the ocean, a multi-metre sea-level rise appears likely.
