Are you sure you have a grip on the percentage of the planets 'ice' we are looking at here Keith? When you look at Greenland an West Antarctica's losses combined do these few glaciers offset the 'trend' for rapid deglaciation across the planet (sea ice included). Peterman is due to shed another chunk this year (not as big as the last but effectively moving the 'ice front' up glacier beyond 'normal cyclical variation') and closer to allowing the seas into the basin underlying the G.I.S.) which would probably nearly account for all of last years 'mass increase' across the Himalayan catchment area?

It worries me more to see the Denialasphere now focusing on such trivia as the above and NSIDC 'sea Ice extent measurements'.......are there no longer any real doubts about what is occurring on the planet to focus on?

Some more info

Data set from arctic.atmos.uiuc.edu/cryosphere/timeseries.anom.1979-2008 Arctic ice on the increase also.You missing the point Grey Wolf IPPC said that the region would be ice free in 35 yrs the reverse is happening .

Might be better for the sea ice thread, 'because it certainly doesn't indicate global cooling.

Is that your own work or from elsewhere?
How about putting a trend line through the data? Or maybe using yearly or seasonal averages rather than just a single day (does the cold April so far this year mean that Britain's weather is getting ever colder?).

Good point but there's seemingly been quite a good upturn since the grim days of 2007

Arctic methane leaks threaten climate

As Arctic sea ice breaks apart, massive amounts of methane could be released into the atmosphere from the cold waters beneath.
High concentrations of the greenhouse gas have been recorded in the air above cracks in the ice. This could be evidence of yet another positive feedback on the warming climate – leading to even faster Arctic warming.
The Arctic is home to vast stores of methane – there are billions of tonnes of methane in permafrost alone. It is a potent greenhouse gas, so a major methane release would greatly accelerate climate change. The gas is found in icy crystals called hydrates beneath the shallow seas that flood some areas of the continental crust, as well as in permafrost. It is also being released from Arctic wetlands.
But this doesn't explain why Eric Kort of the Jet Propulsion Laboratory in Pasadena, California, and his colleagues found patches of methane in remote regions of the Arctic Ocean, far from any of these known methane sources.
The team found the patches during five flights over the Arctic Ocean between 2009 and 2010, as part of a project to systematically map greenhouse gas levels in the atmosphere.

Didn't mean to post this in this thread but cannot change it.

A trend that over the last ten years the ice is thicker now on this particular date than it was 10 yrs ago.

[BornFromTheVoid]

Can you provide evidence that it is thicker? What about the other 364 days, and the other years?
Cherry picking individual days to fit an agenda doesn't prove anything, you can find "evidence" for anything you want with that method.
