Icelandic Glaciers
« on: January 30, 2015, 05:21:43 PM »
The linked reference provides direct measurements of the vertical uplift acceleration of Icelandic crust that can only be accounted for by an associated acceleration of the rate of ice mass loss from Iceland:

Kathleen Compton, Richard A. Bennett and Sigrun Hreinsdóttir, (2015), "Climate driven vertical acceleration of Icelandic crust measured by CGPS geodesy", Geophysical Research Letters, DOI: 10.1002/2014GL062446

"Earth's present-day response to enhanced glacial melting resulting from climate change can be measured using Global Positioning System (GPS) technology. We present data from 62 continuously operating GPS instruments in Iceland. Statistically significant upward velocity and accelerations are recorded at 27 GPS stations, predominantly located in the Central Highlands region of Iceland, where present-day thinning of the Iceland ice caps results in velocities of more than 30 mm/yr and uplift accelerations of 1-2 mm/yr2. We use our acceleration estimates to back-calculate to a time of zero velocity, which coincides with the initiation of ice loss in Iceland from ice mass balance calculations and Arctic warming trends. We show, through a simple inversion, a direct relationship between ice mass balance measurements and vertical position and show that accelerated unloading is required to reproduce uplift observations for a simple elastic layer over viscoelastic half-space model."

I don't know if this link was already posted.
And i also don't know if anyone will take notion of it down here ;)
But it is about Icelandic glaciers, even though one can see changes in Greenland as well.

Tourists Flee Wave from Glacier Collapse

A large wave caused by a glacier calving - the natural process where a large section of ice breaks away - has been caught on camera in Iceland.

Tourists visiting the Breiðamerkurjökull glacier, who were accompanied by an expert guide, can be seen running to safety as the wave approaches the shore.ðamerkurjökull

There are 3 classes of people: those who see. Those who see when they are shown. Those who do not see

Insensible before the wave so soon released by callous fate. Affected most, they understand the least, and understanding, when it comes, invariably arrives too late

Scientists are gathering in Iceland Sunday to memorialize Okjökull — the country’s first glacier to be destroyed by global warming.
Okjökull, nicknamed Ok, lost its status as a glacier 2014. The monument being unveiled at the “funeral” is inscribed with an ominous warning, titled “A letter to the future.”

In 2014, the Icelandic glacier Okjökull was declared dead. Today, scientists, politicians, and members of the public gathered at the site of the former glacier to mourn its passing and hope that such a loss never happens again.
Because of global warming, scientists found, the glacier had lost so much ice that what remained was melting where it sat, a sign of “dead ice.”

Some images of the south side of the Vatnajökull ice cap, showing ice loss between the 1980's and now (circa 30 years).
