Recent changes to Lake Hazen, the world’s largest high-Arctic lake, are from increased heat flow from the area’s known geological features, and not from global warming as per the many alarmist media reports.
vidence supporting this is abundant and reliable.Northeast Canada’s Lake Hazen lies adjacent to the world-class Greenland/Iceland mantle plume (Figure 2).
Mantle plumes are narrow streams of deep inner earth sourced hot rock that spread like a ‘mushroom’ cap beneath the Earth’s surface.
They act to significantly warm overlying rocks, warm and chemically alter overlying oceans, and melt overlying ice masses.
Research by the University of Kansas has confirmed the results of three previous studies all indicating that geothermal heat flow from the Greenland/Iceland mantle plume is the dominant and likely sole cause of anomalous Greenland ice sheet melting. (see here, here, here, and here).
The ground-warming and ice-melting power of this geological feature are estimated to cover 720,000 square miles extending from the northern edge of Ellesmere Island to the eastern shore of Iceland.

Other subglacial lakes in Greenland and Antarctica contain fresh water, generated by melting at the base of the ice. Geothermal heat rises from the underlying rock, and is insulated by the thick ice sheet above.


The Canadian ice sheet is not thick enough to provide this insulation
