New 2012 Record Low Arctic Ice Extent Smashes Previous 2007 Record

NSIDC has (preliminarily) announced the new record low ice extent for 2012.

On September 16, 2012 sea ice extent dropped to 3.41 million square kilometers (1.32 million square miles). This appears to have been the lowest extent of the year. In response to the setting sun and falling temperatures, ice extent will now climb through autumn and winter. However, a shift in wind patterns or a period of late season melt could still push the ice extent lower. The minimum extent was reached three days later than the 1979 to 2000 average minimum date of September 13.

This year’s minimum was 760,000 square kilometers (293,000 square miles) below the previous record minimum extent in the satellite record, which occurred on September 18, 2007.  This is an area about the size of the state of Texas. The September 2012 minimum was in turn 3.29 million square kilometers (1.27 million square miles) below the 1979 to 2000 average minimum, representing an area nearly twice the size of the state of Alaska. This year’s minimum is 18% below 2007 and 49% below the 1979 to 2000 average.

Overall there was a loss of 11.83 million square kilometers (4.57 million square miles) of ice since the maximum extent occurred on March 20, 2012, which is the largest summer ice extent loss in the satellite record, more than one million square kilometers greater than in any previous year.

Read the rest for a fully analysis.  Expect the final review of this year's stunning record low in early October, which will come along with an announcement of the lowest ever September average and the lowest ever monthly average in general.  Further ice retreat is still possible, but at this point it is less and less likely.

Tamino notes what it is that interests the "sceptics" more than this.

Another excerpt from NSIDC:

The six lowest seasonal minimum ice extents in the satellite record have all occurred in the last six years (2007 to 2012). In contrast to 2007, when climatic conditions (winds, clouds, air temperatures) favored summer ice loss, this year’s conditions were not as extreme. Summer temperatures across the Arctic were warmer than average, but cooler than in 2007.

Again, this is not weather, it is dramatic climate change.

But wait for next year.

If the ice recovers slightly - which it may well do if we apply that false statistical analysis 'technique' of regression to the mean - then the deniers will be out in droves saying how arctic ice is recovering, therefore there is no global warming.

Anyone want to bet against me?

Hell, they're doing it already.

Doesn't stop others saying "Natural variability!" as if it's some mystic mantra against reality...

Too much acceptance of the unacceptable.

When it comes tied with someone who doesn't want the US to control them, then the unacceptable is unacceptable. But the unacceptable coming tied with a change in the economy, taking it to new territories, then it is only unacceptable to reject the unaccpetable.

Those comfy people are too comfy.

And they hold all the cards.

mandas, wow, and other climate cowards, do you dare to bet one hundred thousand US dollars that in 2013 the arctic sea ice extent will be less than this year's minimum extension? stand to you religious believe, you cowards, and show that you are true courageous fellows of the hysterical global warming church

blah blah blah kai is out of class again.

wow, is this the only thing you can say "bla bla bla bla .... bla bla bla i pray to al gore my heroe that i will get his blessing to be part of his climate church consensus?? poor guy without any talent and money, and bad looking too.

do you dare do bet 100000 us$ for your religious belief that the arczic sea ice extent in 2013 wil be less than in 2012????

can you please answer using other words than bla bla bla bla, you coward


However, since you never listen to a thing if it isn't libertarian teabagger approved bollocks, why put more effort into it?

You put none in yours.

When they use phrases like "hysterical global warming church" it is a tacit admission that they have no valid scientific argument to make.

"Bla bla bla" is all the response kai warrants.

exusian, you co2 hysteric are wrong: "When they use phrases like “hysterical global warming church” it is a tacit admission that they have no valid scientific argument to make"

correct would be: "When they use phrases like “hysterical global warming church” then they really mean "hysterical global warming church”, basta.

Whenever kai posts, I always imagine the voice of Beaker from the muppets.

See, kai just validated my assertion quite nicely.

September 23, 1:38 am See, kai just validated my assertion quite nicely

climate truth denialists here: arctic sea ice extent is increasing dramatically again, and will continue so, just for your infomation as you are so terribly poor informed, for the next 7 months, hahaha!!!

you have again lost a climate battle, as always, and your collective depression, due to a complete lack of global warming, is well deserved
