Cool...er...um...fascinating image at link.
Don't forget the sunscreen...
Last year stories like this came out about the Greenland ice sheet melting with these images:
http://www.guardian.co.uk/commentisfree ... sheet-melt
Now this particular article explained further on that the Greenland ice sheet did not melt. Regardless, how many people read the whole thing? But they would read the first paragraph which says:
“This is the most frightening picture you will ever see. The information expressed visually here can be summed up in three words: change or die. So let’s take a closer look.”
There are some people, and I have met some of them, due to stories like this one and that they never read completely through, who actually believe that the Greenland ice sheet disappeared in July 2012, and you can’t convince them otherwise.
It is a battle of propaganda, as far as I see it.

Except that is not a picture of the north pole.
While the rate of Arctic sea ice loss is normally fastest during July, the warmest month of the year, ice loss was even faster than usual over the first two weeks of July 2013. As a result, on July 15 extent came within 540,000 square kilometers (208,000 square miles) of that seen in 2012 on the same date. The ice loss is dominated by retreat on the Atlantic side of the Arctic, including the East Greenland, Kara and Laptev seas, and Baffin Bay. In the Beaufort and Chukchi seas and much of the Eurasian coast, the ice cover remains fairly extensive, especially compared to recent summers. Compared to the 1981 to 2010 average, ice extent on July 15, 2013 was 1.06 million square kilometers (409,000 square miles) below average.
During the first two weeks of July, ice extent declined at a rate of 132,000 square kilometers (51,000 square miles) per day. This was 61% faster than the average rate of decline over the period 1981 to 2010 of 82,000 square kilometers (32,000 square miles) per day. The fast pace of ice loss was dominated by retreat in the Kara and East Greenland seas, where the ice loss rate from July 1 to 12 was -16,409 and -17,678 square kilometers (-6,336 and -6,826 square miles) per day, respectively.
The Vast Cost of Arctic Change (Nature, 7/25/13)
We calculate that the costs of a melting Arctic will be huge, because the region is pivotal to the functioning of Earth systems such as oceans and the climate. The release of methane from thawing permafrost beneath the East Siberian Sea, off northern Russia, alone comes with an average global price tag of $60 trillion in the absence of mitigating action — a figure comparable to the size of the world economy in 2012 (about $70 trillion). The total cost of Arctic change will be much higher.

I work daily on this issue and I have never heard anyone who believes this. In fact, this is the first mention I've read anywhere that suggests there are people who believe the Greenland ice sheet disappeared last year.

Antarctic Sea Ice Extent Breaking All Records
http://nsidc.org/data/seaice_index/index.html
Antarctic sea ice extent at the end of July was the highest on record for that day,
growing to 18.077 million sq km. The previous record of 17.783 was set in 2010,
whilst the 1981-2010 average was 16.869.
Ice extent has been above average all year, and, according to NSIDC, is outside the 2 Standard Deviation range now.

Sea ice area also continues to run at well above average.
