the Antarctic bedrock
Sep 1st, 2014 at 11:33pm
 
German researchers have established the height of the Greenland and Antarctic ice caps with greater precision than ever before. The new maps they have produced show that the ice is melting at an unprecedented rate.

The maps, produced with a satellite-mounted instrument, have elevation accuracies to within a few metres. Since Greenland’s ice cap is more than 2,000 metres thick on average, and the Antarctic bedrock supports 61% of the planet’s fresh water, this means that scientists can make more accurate assessments of annual melting.

Dr Veit Helm and other glaciologists at the Alfred Wegener Institute’s Helmholtz Centre for Polar and Marine Research in Bremerhaven, Germany, report in the journal The Cryosphere that, between them, the two ice sheets are now losing ice at the unprecedented rate of 500 cubic kilometres a year.

..
Overall, the southern continent − 98% of which is covered with ice and snow − is losing 125 cubic km a year. These are the highest rates observed since researchers started making satellite observations 20 years ago.

There is no known 'precedence' of a civilised 'Species' before Humankind.

Now there will be.

The theory is that stronger polar winds are ablating the Antarctic Ice sheet, increasing the sea ice.

Nice one: the anticyclones off of Antartica are also, by extension of the same idea, not reaching into the continental land mass of Australia like they used to ... leading to the long observed pattern of decreased rainfall in the south of W.A.

Which has been hypothesised as a symptom of AGW.

Not so sure about that...

'Still unknown is why the southern winds have been getting stronger. Some scientists have theorized that it could be related to global warming, or to the ozone depletion in the Southern Hemisphere, or just to natural cycles of variability.'

All that PERMAFROST in Asia (Siberia) & North America is accelerating in its meltdown.
Vast amounts of Carbon is being released into the atmosphere. That's x6 times as much released in the same amount of time, as that which has been all man-made.
Throw in the fact that if such comes into contact with moisture - then Methane is released (currently at 10% of what is being released).

I'm sorry people's but I think this planet is stuffed.
They have 'dawdled' too long and now its too late.

Can you explain why the methane wasn't catastrophically released in previous warmings?

Do you have any evidence it was not?

Methane release into the planet's atmosphere has previously brought about the greatest Mass Extinction of Life on this planet (more so than the Meteor) by 95%.

It's a worrying thing. But hey, how can we make money out of fixing the world - unless we can ruin it first, right?  Huh

I thought economy meant using only what you really really need but apparently we were all taught the wrong thing at school!

I think you are right DasEnergy (and my you have a long memory  Shocked).

But hey, lets face it - the Budget and Economy are more important! We gotta make money for the Govt to buy more Toys for other people's Wars. !! Tongue
