The Arctic ice melted in 2012 at the greatest speed and loss of area in recorded history. At the end of the summer of 2012, it covered an area of 3.41 million square kilometers, a decrease compared to the negative record of 2007, when the ice covered an area of 4.17 million square kilometers.
The ice in the Arctic Ocean has melted and reached the smallest area in modern history. That's what scientists in Canada say. Scientists will now be required to reassess their predictions of ice-free winters in the Arctic Ocean and of global warming. In both cases it is an acceleration of the schedule.
"Not only did the ice loss break the 2007 record, it did so by a considerable amount." says Jillian Straub, a scientist at the US National Ice Data Center. She was present aboard a Greenpeace ship that was sailing in the Arctic Ocean north of Garland on a trip to observe first-hand the melting of the ice that she studied mainly from satellite photographs.
She and other scientists on the expedition said they were surprised by the rate of melting this year. Ice the size of the Canadian province of Alberta disappeared over the summer, breaking a record and raising concerns about the impact of the process on climate change.
In mid-September, the ice in the Arctic Ocean covered an area of 3.41 million square kilometers, a decrease compared to the negative record of 2007 when the ice covered an area of 4.17 million square kilometers.
"This is an unbelievable record," says Andrew Weaver, a climate scientist who builds models at the School of Earth and Ocean Sciences at the University of Victoria in British Columbia. "This is a tremendous loss of ice." said.
Strobe conducts daily measurements of the ice data - the thickness of the ice layer is measured every hour or two from the deck. It hopes to improve its satellite data with these measurements to assess how much the satellite findings cause the phenomenon to be underestimated.
Ice-free water, which is darker and thinner ice patches absorb more heat from the sun than the white glaciers. This will accelerate global warming in a process that will be almost impossible to reverse.
Straub now estimates that the Arctic Ocean will be ice-free starting in 2030, contrary to previous formal estimates that set the deadline for 2050.
"Without a doubt this will have a huge impact on the climate" she explains. "The sea glaciers help the earth to stay cold by returning most of the sun's energy. Through the removal of the ice, the oceans will absorb all the heat during the summer period." she told Canadian journalists.

In any case, the argument about the expansion of the ice in Antarctica (where of course it is now the vernal equinox - i.e. the end of winter) has reached its peak appearing only on the sites of global warming deniers and I have not found a trace of it on any scientific site.
Are you starting to be like Nimrod? And why should one be ashamed of the funding sources?
That is, this guilt is your invention. In our world this is not evidence but defamation.
It reflects their agenda - of denying any trace of global warming, so that they continue burning oil.
The National Snow and Ice Data Center is not an unknown place.
And these are known data without any dispute.
What is your source for the serious accusation that the website wattsupwiththat receives money from the Koch brothers?
I would appreciate a referral.
One graph to an unknown place on the Internet does not mean that what is written in it is true. WHATS UP WITH THAT is a site that receives money from the Koch brothers. It's like the Soviet Union's Parvada. I don't trust a word written there.
In any case, rest your mind, on the scientific sites, and not on economic sites that probably have a right-wing bias. The sea ice in Antarctica is shrinking http://www.sciencedaily.com/releases/2012/09/120919103610.htm
to the fan
It is not about a drop of ice more than usual but a record of a consistent increase of 33 years!!!
From the article:
NPR did not mention anywhere that the Antarctic sea ice has consistently increased since satellites began measuring the amount of ice 33 years ago, and that the amount of sea ice throughout 2012 had already exceeded the annual average.
Note that the reference is to the Antarctic Sea and not to the continent itself.
I thought that such facts should also be noted in addition to the mainstream.
Only the deniers do not consider the difference between the ice in the Arctic Ocean and the Antarctic.
The ice in Antarctica is for the most part annual, it forms in winter and melts in summer. It is now the end of winter in Antarctica. So there is a little more ice there than usual, well in a few months it will disappear almost completely.
On the other hand, the Arctic Ocean has a large part of perennial ice, one that survives the summer and continues to winter for years. Only in recent years less and less ice survives the summer and the perennial ice is diminishing. This year, as mentioned, we reached a negative peak.

to Tomer,
You should know that global warming causes more water to enter the circulation,
More water equals more precipitation, precipitation in Antarctica turns into ice,
The believed measurements really show more ice accumulation....
in the west of the continent,
while in the east the glaciers are melting,
To include the situation between the East and the West shows... Less ice.
Father this is not true,
According to satellite measurements, the land ice of Antarctica is also increasing.

My father is for you

Somehow it was clear to me that this article would not find its way to your site…. It is not on the agenda
It's a shame, it's a shame that scientific publications that don't align with the almost religious preaching on this site regarding global warming are not considered
Without an article to which the image is linked, the link has no meaning.
In any case, regarding Antarctica, it is known that the thickness of the ice is shrinking, and that there is a large mass of glaciers and their migration, in particular around the tip of land that comes out of Antarctica
Yes, but what does all this mean?
At the South Pole there is a positive record of ice

Isn't there a situation like a red line, where even the opponents of that gloomy forecast of global warming will agree,
Urgently embark on a global struggle against the situation that has arisen.
