Actually it pops up in Political Animal and has your name all over it, shit that must be wicked gear your on for such extensive memory loss!

Sahara's Abrupt Desertification Started By Changes In Earth's Orbit, Accelerated By Atmospheric And Vegetation Feedbacks



One of the most striking climate changes of the past 11,000 years caused the abrupt desertification of the Saharan and Arabia regions midway through that period. The resulting loss of the Sahara to agricultural pursuits may be an important reason that civilizations were founded along the valleys of the Nile, the Tigris, and the Euphrates. German scientists, employing a new climate system model, have concluded that this desertification was initiated by subtle changes in the Earth's orbit and strongly amplified by resulting atmospheric and vegetation feedbacks in the subtropics. The timing of this transition was, they report, mainly governed by a global interplay among atmosphere, ocean, sea ice, and vegetation. Their research is published in the July 15 issue of Geophysical Research Letters.

maybe CO2 causes subtle changes in the Earth's orbit...

Have read of no recent changes in the earths orbit, however the information you provided is most interesting!

More proof that even an statistically insignificant increase in temperature is having an impact.

Also, can anyone else see a girls face in the ice?

Warming melts last stable edge of Greenland icesheet

A three-year spell of exceptionally high temperatures has weakened the ice stream
12:17AM GMT 17 Mar 2014



The last edge of the Greenland ice sheet that had resisted global warming has now become unstable, adding billions of tonnes of meltwater to rising seas.

In a study published in the journal Nature Climate Change, they said a surge in temperature from 2003 had eased the brakes on a long "river" of ice that flows to the coast in northeastern Greenland.

Known as an ice stream, the "river" takes ice from a vast basin and slowly shifts it to the sea - in the same way that the Amazon River drains water.

In the past, the flow from this ice stream had been constrained by massive buildups of ice debris choking its mouth.

But a three-year spell of exceptionally high temperatures removed this blockage - and like a cork removed from a bottle helped accelerate the flow, the study said.

The ice stream, called Zachariae, is the largest drain from an ice basin that covers a huge 16 per cent of the Greenland ice sheet.

From 2003 to 2012, northeastern Greenland disgorged 10 billion tonnes of ice annually into the ocean, the study found.

"Northeast Greenland is very cold. It used to be considered the last stable part of the Greenland ice sheet," said Michael Bevis, an Earth sciences professor at Ohio State University, who led the study.

"This study shows that ice loss in the northeast is now accelerating. So, now it seems that all the margins of the Greenland ice sheet are unstable."

Greenland is estimated to contribute 0.5mm (0.012 inches) to the 3.2 mm (0.13 inches) annual rise in global sea levels.

The main tool in the study was data from a network of 50 Global Positioning System (GPS) sensors along the Greenland coast.

The monitors use Earth's natural elasticity as a stethoscope of the ice sheet. Ice is heavy, so when it melts in massive quantities the land rebounds and the position of the sensors changes slightly.

To get a wider picture, the GPS data was then overlaid with data from three US satellites and a European one that measured ice thickness from space.

"The Greenland ice sheet has contributed more than any other ice mass to sea level rise over the last two decades and has the potential, if it were completely melted to raise global sea level by more than seven metres (22.75 feet)," said Jonathan Bamber, a professor at Britain's University of Bristol.

"About half of the increased contribution of the ice sheet is due to the speedup of glaciers in the south and northwest. Until recently, northeast Greenland has been relatively stable. This new study shows that it is no longer the case."

Yawn, no one cares. Greenland has had less ice in the past.

Nothing to see here except a hysterical warmist.
Move along.

Yes, ever wonder why it was called Greenland?

Interpretation of ice core and clam shell data suggests that between 800 and 1300 AD, the regions around the fjords of southern Greenland experienced a relatively mild climate several degrees Celsius higher than usual in the North Atlantic, with trees and herbaceous plants growing and livestock being farmed. Barley was grown as a crop up to the 70th parallel.

According to ice cores Greenland was hotter around 750AD and 950AD than it is today. From around 700AD-1600AD the temp range as remained fairly consistent within a 2 degree Celcius range when it dropped a bit and is now back in that band/range.

Well, just look at that will you? All those peaks and troughs around for 100s of 1000s of years without the hysterics of CAGW and look where we are today, at the peak of what seems to be a cycle...hmmm I wonder what that means eh?



You think there might have been just a smidge of ice melting around 130000 years ago? What would you blame that on? Mastadon farts?

Been hunting for data to the sea kevel at time of Greenland being a Greenland.

If Greenland ice melt adds 27 foot rise of the ocean. This would wipe out colonised islands along with many seaside towns and cities!
