East Antarctic ice beginning to melt faster

[Chris]

LONDON, Nov 22 (Reuters) - East Antarctica's ice started to melt faster from 2006, which could cause sea levels to rise sooner than anticipated, according to a study by scientists at the University of Texas.

In the study published in Nature's Geoscience journal, scientists estimated that East Antarctica has been losing ice mass at an average rate of 5 to 109 gigatonnes per year from April 2002 to January 2009, but the rate speeded up from 2006.

The melt rate after 2006 could be even higher, the scientists said.

"The key result is that [we] appear to start seeing a large amount of ice loss in East Antarctica, mostly in the long coastal regions (in Wilkes Land and Victoria Land), since 2006," Jianli Chen at the university's centre for space research and one of the study's authors, told Reuters.

"This, if confirmed, could indicate a state change of East Antarctica, which could pose a large impact on global sea levels in the future," Chen said.

Previous estimates for East Antarctica projected anywhere between a 4 gigatonne per year loss and a 22 gigatonne per year gain, according to the report.

Has anyone been able to reach Phil Jones to get his take on this?

 

[CrusaderFrank]

Are we never supposed to lose or gain so much as a single ice cube over the entire planet?

You tell me.

Has anyone been able to reach Phil Jones to get his take on this?

yeah, but they *lost* his response.

all that's left is his value added response.

Is that all you got?

michael mann was asked, but he was busy being investigated for academic fraud.

tough break, kirky, have an almond and cheer up.

 

[Mr. H.]

It is the East Antarctic ice and Chris is the sun! Arise fair Chris-sun and kill the envious moon. It is the east, and Chris is the sun "

 

[Toronado3800]

Its a tough question when Chris asks what we think should be done.

I think we should try to lower our greenhouse gas emissions while not bankrupting ourselves and leaving the world in the hands of less environmentally friendly powers.

Don't fear the results or economic respectability. To reuse my automotive analogy. In 1993 hot rod technology did not have us driving backwards automobiles which couldn't pull a family of 5 up a hill. Z28's made 275 horse and got 26 mpg on the highway! Imagine if Presidents Clinton and Bush had updated CAFE standards so much new hot rods, 16 years later, still "only" made 275 horse but got 30(?) 36(?) mpg.

We use monthly measurements of time-variable gravity from the GRACE (Gravity Recovery and Climate Experiment) satellite gravity mission to determine the ice mass-loss for the Greenland and Antarctic Ice Sheets during the period between April 2002 and February 2009. We find that during this time period the mass loss of the ice sheets is not a constant, but accelerating with time, i.e., that the GRACE observations are better represented by a quadratic trend than by a linear one, implying that the ice sheets contribution to sea level becomes larger with time. In Greenland, the mass loss increased from 137 Gt/yr in 2002–2003 to 286 Gt/yr in 2007–2009, i.e., an acceleration of −30 ± 11 Gt/yr2 in 2002–2009. In Antarctica the mass loss increased from 104 Gt/yr in 2002–2006 to 246 Gt/yr in 2006–2009, i.e., an acceleration of −26 ± 14 Gt/yr2 in 2002–2009. The observed acceleration in ice sheet mass loss helps reconcile GRACE ice mass estimates obtained for different time periods.

Oh this is REAL information? Were Mann or Jones reached for comment on the matter or were they too busy hacking emails?

 

[Toronado3800]

If Mann and them said Exit Glacier by Seward was shrinking I'll verify that with personal information. Or Portage Glacier as well.

And what is the major cause of this, Chris?

The increase in atmospheric CO2, and the reduction in CFCs.
