There is a lot of hot air about the sea ice extent at the moment.
As you can see above, I had a look back at the last 20 years of the "same date" data for the 21st August, at the very good atmos.uiuc.edu site and it shows poor ice cover for this time of year.
This year looks worse then 2007, and that year was regarded as very poor.
You would expect ice to melt during summer but the Cryosphere Today site page makes 2012 stand out as something to worry about!
I have to admit that this years "same date" data looks far worse then recent years, how bad it will be remains to be seen, in a few months time the ice will grow back maybe more then recent times maybe less, but it will grow back!
Those of you who follow data from the output of the Sun will know, the Sun is being quiet at the moment and that normally means more ice in the winter but as far as summer is concerned that can show ice melting in warm warters something you don't see in winter!
I also had a look at this issue a few moths ago with a lookback to the start of the year also using "same date" data for each decade and noticed an increase in ice, with 2012 being very good:http://climaterealists.com/index.php?id=9764
Ice cover goes up and down all the time and since the Earth has warmed up during the past few decades, due to an increase in solar activity, NOT MAN MADE CO2, you would expect to see some changes at the poles with warm currents changing the ice cover.
My take on this is that the warm waters in 2012 have migrated poleward from the equator in the same way they also did that in 2007, and will no doubt do it again in the future.
In my opinion this would mean that waters near the equator are cooling!
If any of you can verify this change at the equator please drop me a line
