And now it's global COOLING! Record return of Arctic ice cap as it grows by 60% in a year http://www.dailymail.co.uk/news/art...caps-grows-60-global-warming-predictions.html
compare that with this.... one of these groups is full of shit... it is really annoying. http://nsidc.org/arcticseaicenews/ Sea ice extent for August 2013 averaged 6.09 million square kilometers (2.35 million square miles). This was 1.03 million square kilometers (398,000 square miles) below the 1981 to 2010 average for August, but well above the level recorded last year, which was the lowest September extent in the satellite record. Ice extent this August was similar to the years 2008 to 2010. These contrasts in ice extent from one year to the next highlight the year-to-year variability attending the overall, long-term decline in sea ice extent. Extent in the Beaufort and Chukchi seas has dropped below average, after near average conditions in July. The only region with average extent is the East Siberian Sea. Conditions in context Figure 2.

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. August 2013 compared to previous years Figure 3.

This yearâs August extent was the sixth lowest in the 1979 to 2013 satellite record. 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 â10.6% per decade relative to the 1981 to 2010 average. Water near the pole Figure 4.

Credit: NSIDC/University of Bremen High-resolution image Earlier this summer, there was considerable interest in seeing liquid water in the North Pole Environmental Observatory (NPEO) web cam. As explained in our August 7 post, that region was simply a shallow melt pond of water atop the ice and not an actual opening in the ice. Nevertheless, our August 19 post described an extensive region of low ice concentration located fairly close to the pole. Now, a large hole (roughly 150 square kilometers or 58 square miles) of near-zero ice concentration appears to have opened up at about 87 degrees North latitude. Small areas of open water are common within the ice pack, even at the North Pole, as the ice pack shifts in response to winds and currents, resulting in cracks (called leads) in the ice. The current opening seen in our satellite imagery is much larger. In 2006, a larger polynya appeared in the Beaufort and Chukchi seas, but it was much farther south.

Such openings in the ice occur two ways: through winds pushing the ice apart, or through melting. Both processes likely played a role in forming the current opening, but another key factor is a significant amount of thin, first-year ice in the region. This thin ice was more likely to melt completely than surrounding thicker ice. Heat from the ocean also contributes to melting of the ice from below, even though air temperatures have been below average in the region. Buoys that measure ice mass can provide information on surface and bottom melting. During the summer of 2013 there were six ice mass balance buoys deployed in the Arctic over a wide area (red dots in Figure 5). The buoys were deployed in undeformed, multiyear ice, with a thickness between 2.2 and 3.5 meters (7 and 11 feet) before melt began. Data from the buoys show that the amount of surface ice melting ranged from 0 in the central Arctic, to 75 centimeters (30 inches) in the Beaufort Sea. Bottom melting varied from 8 to 108 centimeters (3 to 43 inches). The largest amount of bottom melting was observed at a buoy near the ice edge in the Beaufort Sea. This buoy had the largest total amount of melt, thinning from 339 centimeters (133 inches) in early June, to 157 centimeters (62 inches) on August 28. Ice thicknesses at the other buoys on August 28 ranged from 121 to 267 centimeters (48 to 105 inches). While bottom melting is continuing in some locations, most of this yearâs surface melting has occurred. Data from the ice mass balance buoys are available at http://imb.crrel.usace.army.mil.

So we can use current photo evidence, or your 10 year old chart? What's your next argument? Things fluctuate? Duh, that's kind of what we've been telling you all along. The climate changes. We get that. Come back when you actually have something other than wild eyed speculation and conjecture.
Typical of the retarded left to use charts and graphs to back their argument even though they are wildly outdated and have no relevance to current events. Might as well show a housing chart from 2007 to back your case for sub prime lending.
That's what I'm reading, too. Fresh water floats on salt water. So the extent is greater but the mass and volume are... not reported in this article.
Do the math. The "10 year old chart" is in square kms. 920,000 square miles is roughly 2,400,000 square kilometers. To obtains the base on which this growth occurred, 2400000/60*100 = 4,000,000. So the extent this year is 6.4 million square kms. <img src="http://upload.wikimedia.org/wikipedia/commons/thumb/c/c2/Seaice-1870-part-2009.png/664px-Seaice-1870-part-2009.png"> "1870-2000 Northern hemisphere sea ice extent in million square kilometers. Blue shading indicates the pre-satellite era; data then is less reliable. In particular, the near-constant level extent in Autumn up to 1940 reflects lack of data rather than a real lack of variation." These upticks have happened many times before, but there's going to have to be a lot of them before one can say the trend is over.
What is your argument? Given the recent expansion of the ice. That the mass of ice is still smaller than on chart... what years are you comparing. . That we do not know the mass of ice? That the 10 year chart is not like the current chart? Come on... make a point. Show us evidence of current global warming with some science to back it up. Or admit that the earth has not warmed for 16 or so years, the IPCC models have failed. And you, me and the scientists have no science showing man made co2 is causing warming. Really ricter... in the past you acted like there was no doubt man made co2 was causing warming. You acted like you had science showing that and that we were the goofs. Do you still think you have science showing man made co2 causes warming?
