A leaked report to the UN Intergovernmental Panel on Climate Change (IPCC) seen by the Mail on Sunday, has led some scientists to claim that the world is heading for a period of cooling that will not end until the middle of this century.
Relatively cool conditions over the central Arctic Ocean continued, a pattern that has characterized this summer. Temperatures at the 925 hPa level in the high Arctic (north of Greenland to the North Pole) were 0.5 to 3 degrees Celsius (1 to 5 degrees Fahrenheit) below the 1981 to 2010 average. In comparison, temperatures in coastal areas of the Arctic were mostly near average, and temperatures in the Barents and Beaufort seas were about 2 degrees Celsius (4 degrees Fahrenheit) above average. The distribution of the temperature anomalies can be related to the sea level pressure pattern. Below-average sea level pressures were linked to cloudy and cool conditions near the North Pole and extending into the northern North Atlantic. In contrast, above-average pressures dominated the Eurasian coast.
A one year "turn around" is supposed to indicate a trend?
But what a huge turn around in ice cap level
August 2013 ice extent was 2.38 million square kilometers (919,000 square miles) above the record low August extent in 2012. The monthly trend is –10.6% per decade relative to the 1981 to 2010 average.

True it isn't new information, but we are still considered terrorists and boat rockers if we are climate change deniers or question the 'science' behind the global elites power grab.

Cycles or climate change - doesn't really matter much how you describe it, in either case things change from their current state to something else. It's not a matter perception.
Don't understand what your point is.edit on 06/06/12 by Mads1987 because: (no reason given)
of course it does not indicate a trend, but 60% increase in the amount of ocean covered with ice compared to this time last year is a big turnaround.(from the OP source)
For an actual recovery to be established you’d have to see year after year of expanding and thickening ice. And we’re not anywhere near that. Quite to the contrary, since 1979 we’ve lost 55% of sea ice area and 80% of sea ice volume.
Area and volume. These two measures are the most important when figuring out the health of ice. Area measures how much ice covers the Arctic. Volume measures the total mass of ice. But between these two measures, volume is most important. A foot thick film of ice covering 3 million square kilometers of the Arctic is many times less ice than a ten meter thick sheet covering the same region.
In the end, 2013 ice is overall thinner and more spread out than 2012 ice. And this state makes it vulnerable to rapid melt, opening of holes in the central ice, separation of large sections of the sea ice, and disruption by storms and strong wind events. Overall, the ice pack is less unified than even 2012. So concern levels remain high for new record losses come end of summer. Much higher, in fact, than sea ice area and extent measures would typically lead one to believe.
And as for shouts of ‘recovery,’ they are hollow as the central Arctic’s sea ice.
