Why Antarctica also doesn't need 'saving'

In an article today, Eyes Turn to Antarctica as Study Shows Greenland’s Ice Has Endured Warmer Climates, NYT blogger Andy Revkin says,

"My answer would be that Greenland doesn’t need “saving,” Antarctica needs much more observation and analysis"

Here's why Antarctica also doesn't need "saving":

New paper finds Antarctica snow pack will continue to grow during 21st century

New paper finds no change in Antarctic snowmelt since measurements began in 1979

New paper shows Antarctic temperatures haven't increased over past 500 years

Shocking warming in Antarctica - almost back to temperature in 1850

Inconvenient truth: Antarctica sea ice extent growing 1.43% per year

New study finds growth of Antarctic sea ice accelerated 53% since 2006

Antarctica sea ice shows accelerating increase over past 30 years

Antarctic Temperatures and Ice Extent Not Unprecedented

GRACE satellite data shows Antarctica is gaining ice mass

New paper shows sea temperatures near Antarctica were about 10°C warmer 12,000 years ago

Greenland ice SIMPLY WOULD NOT MELT in baking +8°C era 120k years ago

Scratch off yet another IPCC doom warning

Scientists analysing ancient ice samples say that the Greenland ice sheet withstood temperatures much higher than today's for many thousands of years during a period of global warming more than 120,000 years ago, losing just a quarter of its mass. It had been widely suggested - by the UN Intergovernmental Panel on Climate Change for instance - that any such warming would melt the entire sheet, leading to massive sea-level rises.

The new research was carried out by analysing a 2.5km long ice core drilled from the Greenland ice last year by a major scientific expedition involving top boffins from around the world. The core data showed that 115 to 130 thousand years ago, temperatures above the Greenland ice were much higher than they are today: 8±4°C, in fact.

Until now it had been generally assumed that any such temperature rise - or indeed a much lesser rise of more than 3°C - would mean that all the Greenland ice would inevitably melt, causing the oceans of Earth to rise by as much as 7 metres. Based on the current IPCC status report, the climate-hardliner hippies at Greenpeace have this to say (pdf):

There is a major risk that the warming expected during the next five decades would trigger meltdown of the Greenland ice sheet ...
Ice sheet models project that a local warming of larger than 3°C ... would lead to virtually a complete melting of the Greenland ice sheet ...

But we now know that the Greenland ice was exposed to much greater heat for many thousands of years and lost only a quarter of its mass, so the models are evidently wrong and another IPCC doom warning has been consigned to the dustbin of history (previously the organisation has attracted widespread ridicule for suggesting that the glaciers of the Himalayas would all be gone by 2035 and that the Amazon rainforest might suddenly catch fire, burn up and vanish).

"The good news from this study is that the Greenland ice sheet is not as sensitive to temperature increases and to ice melting and running out to sea in warm climate periods like the Eemian, as we thought," explains Dorthe Dahl-Jensen of Copenhagen uni, one of the lead boffins working on the ice core research.

Some of the participating scientists suggested that even though we are now pretty sure we're safe from the Greenland ice sheet, we may still be flooded out of our homes at some point by meltwater from the even bigger and chillier Antarctic ice. However recent research has shown that big ice shelves down there, which had been thought to be melting, are actually not: that nothing new is going on in the much-discussed Western Antarctic peninsula: and that in fact the mighty sheet froze into being at a time when the atmosphere held much more carbon than it now does. It will also be well known to regular readers that the sea ice around the Antarctic coasts is steadily increasing in area year after year - baffling climate scientists and further undermining confidence in their models.
