Faster and Faster: Rising Heat from Inner Earth Hot Spots Are Melting Greenland Glaciers from Below

% of readers think this story is Fact. Add your two cents.


In northeast Greenland, researchers have measured the loss of heat that comes up from the interior of the Earth; this enormous area is a geothermal ‘hot spot’ that melts the ice sheet from below and triggers the sliding of glaciers towards the sea

Greenland’s ice sheet is becoming smaller and smaller. The melting takes place with increased strength and at a speed that no models have previously predicted.

Today, in the esteemed journal Scientific Reports, researchers from the Arctic Research Centre, Aarhus University, and the Greenland Institute of Natural Resources present results that, for the first time, show that the deep bottom water of the north-eastern Greenland fjords is being warmed up by heat gradually lost from the Earth’s interior. And the researchers point out that this heat loss triggers the sliding of glaciers from the ice sheet towards the sea.

Icelandic conditions

“North-East Greenland has several hot springs where the water becomes up to 60 degrees warm and, like Iceland, the area has abundant underground geothermal activity,” explains Professor Soren Rysgaard, who headed the investigations.

For more than ten years, the researchers have measured the temperature and salinity in the fjord Young Sound, located at Daneborg, north of Scoresbysund, which has many hot springs, and south of the glacier Nioghalvfjerdsfjorden, which melts rapidly and is connected to the North-East Greenland Ice Stream (NEGIS).

By focusing on an isolated basin in the fjord with a depth range between 200 and 340 m, the researchers have measured how the deep water is heated over a ten-year period. Based on the extensive data, researchers have estimated that the loss of heat from the Earth’s interior to the fjord is about 100 MW m-2. This corresponds to a 2 megawatt wind turbine sending electricity to a large heater at the bottom of the fjord all year round.

Heat from the Earth’s interior – an important influence

It is not easy to measure the geothermal heat flux – heat emanating from the Earth’s interior – below a glacier, but within the area there are several large glaciers connected directly to the ice sheet. If the Earth releases heat to a fjord, heat also seeps up to the bottom part of the glaciers. This means that the glaciers melt from below and thus slide more easily over the terrain on which they sit when moving to the sea.

Although it may be biting cold over the water, heat from the Earth’s interior is transported to the bottom water of Young Sound, North-East Greenland.

“It is a combination of higher temperatures in the air and the sea, precipitation from above, local dynamics of the ice sheet and heat loss from the Earth’s interior that determines the mass loss from the Greenland ice sheet,” explains Soren Rysgaard.

“There is no doubt that the heat from the Earth’s interior affects the movement of the ice, and we expect that a similar heat seepage takes place below a major part of the ice cap in the north-eastern corner of Greenland,” says Soren Rysgaard.

The researchers expect that the new discoveries will improve the models of ice sheet dynamics, allowing better predictions of the stability of the Greenland ice sheet, its melting and the resulting global water rise.

      I think its the earths core has felt the cold beginnings of geoengineering. Kind of like the planet has been given the flu and its naturally in a fever state trying to fix itself. We are a Virus type race. Ive got no scientific evidence but it feels right when you think about it? In a basic way of thinking

      Alton. Check this. Im watching the 2017 montreal comedy festival and the last comedian was joan rivers just now, my memory isnt perfect so i asked Google when did joan rivers die and thier answer is 2014! TRUE MANDELA EFFECT of a corporation changing its product to mentally mess with people. I see people start to really lose it over time after thinking the mandela effect is a real dimensional topic when in fact its a bored billionaires game for a one dollar bet…

      Some psychics and Wilcock etc say that while earth is approaching the galactic center it causes heating of the poles inside the earth, so may be that is the reason why now the heat is melting the ice in poles. Same is happening in Antarctica. Otherwise I don’t think there is global warming. Morocco got just snow…
