Why Greenland is melting faster today...?

It is the sea temperature, not  the air temperature that determine how fast Greenland’s ice cap melted at the end of the last ice age.

The study, published in the journal Paleoceanography, was conducted by an international team of researchers headed by senior researcher Paul Knutz of the Geological Survey of Denmark and Greenland (GEUS).

”Our study included analyses of the marine temperature in the upper water strata, and they indicate that the temperature during the period of deglaciation was relatively high,” says Knutz.

"We can see that the high temperatures start immediately before and continued during periods when a lot of icebergs broke off from glaciers and when a lot of melt water was produced,” he adds. “Therefore we interpret the temperature anomalies as something that resulted in increased melting and a retreat of the ice cap.”
