Huh?
And what about the Antarctic ice increasing?
The Arctic, an ocean surrounded by land, responds much more directly to changes in air and sea-surface temperatures than Antarctica, Serreze explained. The climate of Antarctica, land surrounded by ocean, is governed much more by wind and ocean currents. Some studies indicate climate change has strengthened westerly winds in the Southern Hemisphere, and because wind has a cooling effect, scientists say this partly accounts for the marginal increase in sea ice levels that have been observed in the Antarctic in recent decades.

“Another reason why the sea-ice extent in the Antarctic is remaining fairly high is, interestingly, the ozone hole,” Serreze told Life’s Little Mysteries. This hole was carved out over time by chlorofluorocarbons, toxic chemicals formerly that were used in air conditioners and solvents before being banned.“The ozone hole affects the circulation of the atmosphere down there. Because of the ozone hole, the stratosphere above Antarctica is quite cold. Ozone in the stratosphere absorbs UV light, and less absorption [by] ozone makes the stratosphere really cold. This cold air propagates down to the surface by influencing the atmospheric circulation in the Antarctic, and that keeps the sea ice extensive.”

But these effects are very small, and Antarctic sea-ice levels have increased only marginally. In the coming decades, climate models suggest rising global temperatures will overwhelm the other influences and cause Antarctic sea ice to scale back, too.

The extent of Arctic sea ice at its summertime low point has dropped 40 percent in the past three decades. The idea that a tiny Antarctic ice expansion makes up for this — that heat is merely shifting from the the Southern Hemisphere to the Northern and therefore global warming must not be happening — is “just nonsense,” Serreze said.

Antarctic land ice mass is of course melting.

Comiso and Nishio report that trends in sea ice extent and area in the Arctic over the period of their analysis [1979 to 2006] were -3.4 ± 0.2 and -4.0 ± 0.2% per decade, respectively, while the corresponding trends in the Antarctic were +0.9 ± 0.2 and +1.7 ± 0.3% per decade.

No website which posts Denier propaganda and describes climate scientists as "alarmists" can be taken at all seriously. Except by climate trolls lik eyourself, of course, who merely cut n' paste from Denier websites whatever selective bits of information seem to them to support Denierism.

Pathetic, troll.

You weren't missed. But you're gonna have to work real, real hard to regain 'king troll' status.

Now, you're just a petty annoyance.

1 day ago – Ice in the Arctic melts in summer and grows in winter. It started growing again on Monday. In the 1980s, Meier said, summer sea ice would ... "Man-made global warming has melted more sea ice and made it thinner over the last couple decades with it getting much more extreme this year, surprisingly so, said snow and ice data center director Mark Serreze.

“Recently the loss of summer ice has accelerated and the six lowest September ice extents have all been in the past six years,” Serreze said.“I think that’s quite remarkable"... "“Arctic sea ice is one of the most sensitive of nature’s thermometers,” said Jason Box, an Ohio State University polar researcher.

"What happens in the Arctic changes climate all over the rest of the world, scientists have reported in studies." ... "Scientists at the snow and ice data center said their computer models show an Arctic that would be essentially free of ice in the summer by 2050, but they add that current trends show ice melting faster than the computers are predicting."

Extreme weather could come with record Arctic Ocean ice melt

...The ice that for millennia nearly covered the Arctic Ocean has been melting so quickly that the polar ice cap today is the smallest it's been since satellite record-keeping began more than 30 years ago.

Today, the polar ice cap is about half the size than it was in 1980. And the remaining ice is thinner than it used to be, making it more likely to melt next summer." cbs

- Arctic could be ice free well before 2050
- May change jet stream pattern with more storms and extremes in temsp

-2012 possibly hottest year on record.

Global warming is a lie.
No amount of lies by the warmers can change that.
Nobody, even Obama, gives a **** about GW anymore.

The goal would be for you to find something else to do besides scarring the children of the world with your USELESS BABBLE. No will never miss you. We may be in shock when you the commander of useless babble tainted with hate covered with spam cut and paste goes away.Before you do go away are you going to answer that 2nd grade question?

Ice at all-time low in the Arctic - Deniers ignore.

Sea ice in Antarctic on a gradual rise - Deniers orgasm in delight, and proclaim an end to global warming.

That....is Denierism, folks. It sure ain't science.

The two poles have a see saw relationship. One goes up the other goes down. What would be bad is if both went up or down at the same time.

Having the Arctic this far down is bad, period.

Sea ice is increasing even though temperatures in the Antarctic are warming. Land ice in the Antarctic is of course melting.

More than you know perhaps. The axis of the earth would have to move quite a bit.
