Speed of glacier retreat worldwide 'historically unprecedented', says report
Researchers have recorded rapid rises in meltwater and alarming rates of glacial retreat, which are accelerating at a pace double that of a decade ago

The worlds glaciers are in retreat. The great tongues of ice high in the Himalayas, the Andes, the Alps and the Rockies are going back uphill at ever greater speeds, according to new research.
And this loss of ice is both accelerating and historically unprecedented, say scientists who report in the Journal of Glaciology.

In the past year or so, researchers have identified rapid rises in meltwater and alarming cases of glacial retreat in Greenland, West Antarctica, the Canadian and Alaskan coastal mountains, in Europe and in the Himalayan massif. They have also watched glaciers pick up speed downhill. One satellite-based study, confirmed by on-the-ground measurements, of the Jakobshavn glacier in Greenland, confirms that the river of ice is now moving at the rate of 46 metres a day, 17 kilometres a year, which is twice the speed recorded in 2003, which in turn was twice as fast as measured in 1997.
The World Glacier Monitoring Service, based at the University of Zurich in Switzerland and with partners in 30 countries, has been compiling data on changes in glaciers over the last 120 years. And it has just compared all known 21st century observations with data from site measurements, aerial photography and satellite observations and evidence from pictorial and written sources. Altogether, the service has collected 5,000 measurements of glacier volume and changes in mass since 1850, and 42,000 records of variations in glacier fronts from records dating back to the 16th century.
And the evidence is clear: the glaciers are in retreat, worldwide, and the retreat is accelerating.

Watch the disappearance of this glacier over a period of only 7 years. This is sad and alarming!

But, hey, Kissinger's plan for our foreign policy in the Third World was depopulation of what he called 'useless eaters.'
And don't worry a bit! Because the top 1/10 of 1% has it covered. They've already made their plans...and really, doesn't it warm your heart to know the Waltons, the Koch brothers and Sheldon Adelson will all survive while you and your family die?

Part of the science about co2 claims that co2 keeps gathering heat for as much as four decades. Which means that the co2 we release today will continue to gather heat from the sun until 2055.
