Sure is better than all those propaganda cartoons by ur hack heroes at skepticalscience. Those jerks spend most of their time fabricating ficticious graphs to amuse the pilgrims.We will see what happens next year. The volume and depth of the sea ice hasn't recovered and the one year ice really is dictated by weather.
This is why one year can see a huge lose and the next can look like it is recovering. Look at the long term trend.
About the same as 2008-2009...Weather has over a million square miles of forcing on year to year sea ice in extent.
Now THIS is the chart we ALL ought to be using. The ice VOLUME. Thanks Matthew.
Bad enough that most folks look at those sea ice exte t pics and think thats the actual polar ice cap when its really coloring white a lot of open ocean with as little as 15percent ice cubes floatjng in it.
Ice is a very nonli near indicator kf warming. Cross 32deg by the slightest in either direction and you get dramatic effects. Thats why I dont get hysterical over ice.
Btw The 15percent definiton enhances volatility and drama. And ks the reason that wj ds and currents have such a large effect
Fecal, you dumb ass, that is a graph from the University of Washington.
Polar Science Center » Arctic Sea Ice Volume Anomaly, version 2
Sea Ice Volume is calculated using the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS, Zhang and Rothrock, 2003) developed at APL/PSC. Anomalies for each day are calculated relative to the average over the 1979 -2011 period for that day of the year to remove the annual cycle. The model mean annual cycle of sea ice volume over this period ranges from 28,700 km3 in April to 12,300 km3 in September. The blue line represents the trend calculated from January 1 1979 to the most recent date indicated on the figure. Monthly averaged ice volume for August 2013 was 5,800 km3. This value is 66% lower than the mean over this period, 76% lower than the maximum in 1979, and 0.8 standard deviations below the 1979-2013 trend. August ice volume was about 1400 km3 larger than in August of 2012 and within 200 km3 of the 2010 August ice volume. While ice volume at the maximum during April was on par with the previous two years, reduction in ice volume during the summer month was less than in previous years. August ice volume showed the first increase since 2008 but is still below the long-term trend line.
