The Wicked Greenland Soothsayers of the West say “I’m Melting”, now “How much energy is required to melt all the ice in Greenland?”

How much energy is required to melt all the ice in Greenland?
How much ice is there in Greenland?
“The Greenland ice sheet (Kalaallisut: Sermersuaq) is a vast body of ice covering 1,710,000 square kilometres (660,235 sq mi), roughly 80% of the surface of Greenland. It is the second largest ice body in the world, after the Antarctic Ice Sheet. The ice sheet is almost 2,400 kilometres (1,500 mi) long in a north-south direction, and its greatest width is 1,100 kilometres (680 mi) at a latitude of 77°N, near its northern margin. The mean altitude of the ice is 2,135 metres (7,005 ft).[1] The thickness is generally more than 2 km (1.24 mi) (see picture) and over 3 km (1.86 mi) at its thickest point. It is not the only ice mass of Greenland – isolated glaciers and small ice caps cover between 76,000 and 100,000 square kilometres (29,344 and 38,610 sq mi) around the periphery. Some scientists predict that climate change may be about to push the ice sheet over a threshold where the entire ice sheet will melt in less than a few hundred years. If the entire 2,850,000 cubic kilometres (683,751 cu mi) of ice were to melt, it would lead to a global sea level rise of 7.2 m (23.6 ft).”

2,850,000 cubic kilometers of ice in Greenland.
So claim of a 100 years to melt 2,850,000 cubic kilometers of ice. Hmmm… we’ll get back to that.
How much energy to melt ice?
“When ice melts, it absorbs as much heat energy (the heat of fusion) as it would take to heat an equivalent mass of water by 80 °C, while its temperature remains a constant 0 °C.” – wikipedia on ice
Ok, that’s very cool, it takes a lot of energy to melt ice. Pardon the pun.
