Sea Ice update...

We are a couple weeks from the Arctic sea ice minimum.   I thought I'd give an update of where global sea ice is at. 
 
Starting with the Antarctic:  still well above normal
 
 
The Arctic Sea ice is approaching this year's minimum.  As of now it looks like it'll be pretty close to last years minimum, which was in the middle of the pack of the last dozen.   Meaning there is no Arctic Ice death spiral.

If we looks an the anomaly graph, we can also that the ice has stabilized.  The extreme minimum of 2012 caused by a strong Arctic storm, has stopped the wild gyrations as we can see in this graph.
 
The NW passage also won't be open this year as the channels are jammed with old or new thick ice.

Climate Alarmism du jour...

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.

Antarctic

Remember when AGW was supposed to be melting the Antarctic and we were all going to drown from the rising sea levels.   Well, nevermind.
