Loss of ice from The Greenland Ice Sheet currently contributes approximately 1 mm/year to global sea level (Enderlin et al., 2014). The most rapidly changing and fastest flowing parts of the ice sheet are tidewater glaciers, which transport ice from the interior of the ice sheet directly into the ocean. In order to better predict how Greenland will contribute to future sea level we need to know more about what happens in these regions.
Tidewater glaciers meet the ocean at the calving front (Fig. 2), where ice undergoes melting by the ocean (“submarine melting”) and icebergs calve off into the sea. In recent decades, tidewater glaciers around Greenland have retreated (due to increased loss of ice at the calving front) and started flowing faster. This in turn causes more ice to be released into the ocean, contributing to sea level. Understanding the cause of these changes at tidewater glaciers is an ongoing topic of research.

Confirmation of geothermal power under the Greenlandic glacier
Ágúst Arnbjörnsson, a pilot at Icelandair, took this nice picture yesterday across Greenland on the way from Keflavik to Portland, at 34,000 feet (10.4km). It clearly shows the same phenomenon and I blogged yesterday in Greenland ice caps, some west of Kulusuk. There seems to be a crack in the glacier and three gusts rise out of the crack, but the moth fights with a wind in the northwest direction. Unfortunately, we do not yet have a precise location on this phenomenon, except that it is about 75 km from Kulusuk. It is noteworthy that the mall is clear even from more than 10 km high. I thank Gunnarsson, the captain of Sigmund, for the information.

Not this old chestnut again? Oh the worlds glaciers are melting and the seas will rise.
Listen very, very closely the Earths glaciers are irrelevant in the whole scheme of things.
I've already put the data on here but I will tell you again and you will have to look it up yourselves else you'll say it's not true.
Every day, that's every day there are gazillions of cubic meters of water added to the words oceans and seas. Way, way more than the puny glaciers can ever add to them and the seas have not rose one iota.
Just look up at the world volume of river outputs then come back with any silly argument that melting glaciers will make the sea level rise.
So how can there be a Net "Gain" of water in the oceans, when the cycle is always occurring?
