You may have noticed recent news articles about collapsing Antarctic icesheets. Here I present some graphs and a map as counterpoint. Please tell me how decreasing sea temperatures (first graph), steadily increasing sea ice levels (second graph and map) and stable air temperatures can co-exist with an apparent melting glacier??? Things that make you go hmmmmm.

Update to Sea Ice update.
Most datasets have the 2013 Arctic Sea Ice minimum extent as the highest since 2006 except for 2009:
And oh by the way, the Antarctic Sea Ice maximum is at record high values:

That time of year
This is the time of year when sea ice discussions ramp up.
Antarctic sea ice has reached its minimum extent/area on the positive side. Its long term trend is also on the positive side. So much for melting poles.
The Arctic sea ice is nearing its maximum. Arctic sea ice has had an interesting growth season. The areas(Hudson Bay and Baffin Straight) last year which had significant negative anomolies are doing just fine now. For example the Baffin Straight/Newfoundland coast has almost 500K sq.km more sea ice than this time last year. This year the Barent and Kara Sea are well below average. But the Bering Sea is well above normal. So overall we are within 500K sq.kms of normal, with in 1 standard deviation from normal.

Almost Fall
The Autumn Equinox happens at 5:04 AM this Friday, September 23rd. Snow covers a good chunk of the Canadian Arctic Archipeligo. The Arctic sea ice reached its minimum a week ago, second lowest in the satellite era (but not lowest in paleoclimatological record, discussed here) despite the very late start of the Eastern Canadian/Western Greenland freeze season due to a prolonged period of a strong negative AO atmospheric circulation (discussed here) which undoubtedly affected the melt season.
