Greenland's meltwater increasing rate of sea level rise

Researchers analyzed ice core data from Greenland to study surface melt and runoff rates. Ice cores, drilled from ice sheets or glaciers, contain climate data like atmospheric CO2 levels. The data spans 339 years, with meltwater signs dating back to the mid-1800s, aligning with the Industrial Revolution. Recent findings show Greenland's ice sheets are melting faster than in the past 350 years. According to the UN, Greenland's meltwater accounts for about 20% of global sea level rise. If all Greenland's ice melted, sea levels would rise by 7 meters.

What percentage of the world's sea level rise is contributed by meltwater from Greenland?

What would happen to sea levels if all the ice in Greenland melted?
