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

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
