The year 2013 marks the first October with an extent above 8 million square kilometers (3.09 million square miles) since 2009 and only the second since 2006.
Ice grew at rates slower than average through most of December, at 59,500 square kilometers per day (23,000 square miles per day) compared to the 1981 to 2010 average of 62,400 square kilometers per day (24,100 square miles per day). At the end of the month the extent was 750,000 square kilometers (289,600 square miles) below the 1981 to 2010 average and nearly identical to the extent at the end of 2012. nsidc.org/arcticseaicenews/
From the article you cite in your comment. "the natural tendency is for the large departure to dampen out, so that, overall, ice extent stays on the long-term downward trajectory that will eventually lead to seasonally ice free conditions as the Arctic continues to warm in response to rising atmospheric concentrations of Greenhouse gases." Also, consider that extent is not the same thing as ice volume.. ie, thin ice with a large extent can be much less ice overall. sites.google.com/site/pettitclimategraphs/sea-ice-volume As the temperature gradient lessens, so the weather systems at the poles breaks down.. cold streams of air 'kink' and spread cold weather further south (ie, USA cold winters).. however, the context for this is global warming and a general lessening of ice at the poles over time. It is similar to how Greenland's melting ice pumps cold water into the sea.. this does not mean that the world is getting colder, but that it is getting warm enough for the ice to melt. science.nasa.gov/science-news/science-at-nasa/2012/24jul_greenland/ The increase in global temperatures is unprecedented.. it is so rapid that Greenland has not had time to melt yet. It is now warmer than in the medieval warm period and temperatures are still increasing. en.wikipedia.org/wiki/Medieval_Warm_Period
Bedankt! Context for people who don't get it: Humboldt is a teaching method for Dutch schools, and this video is linked on a piece of schoolwork. @nielsvh8989 is wishing the students who come here good luck with the schoolwork.
it is considering how rapid the climate changes are. try and find anything similar in recent earth's history that hasnt killed most of the life on the planet as a result.
These video's are funny as hell. Notice how there's no snow in Alaska, very little in northern Canada, none in Russia or the United States. I guess the snow fall that extends from the polar region down through Canada & the northern united states every year is just an illusion.
i find it interesting that 2007 on is when u actually see a dramatic difference. Funny because that is when the world was consumed with global warming. I find these images tampered with and not the truth.

kbryancourville Perhaps the title of the animation will tell you why it doesn't show snow in those places.....
How would you know either way?

do you not understand how significant 5 years is on a billion some odd year old calendar is?
Aan iedereen van Humboldt suc6
Bedankt!

2013 please...
We okay, we can go to or 3 times that again
here is a statistical analysis of trends in sea ice extent in both polar oceans

The end of the ice age!
Mamen est passer par la
