From BBC News:
For the period 2000-2008, melting Greenland ice raised sea levels by an average of about 0.46mm per year.

Since 2006, that has increased to 0.75mm per year.

In total, sea levels are rising by about 3mm per year, principally because seawater is expanding as it warms.

“If you multiply these numbers up it puts us well beyond the IPCC estimates for 2100”
