northern hemisphere is cooling faster

Now you can see the the very dar magenta at the far north is expanding rapidly. There are some areas where there is a local increase of temperature, like the blue cell over Tibet. But the green is completely below Iceland now.
I am watching the red circle centered on Sri Lanka, to see if it disappears as the earth cools. If id does, it may come back later. Australia is a slight bit warmer, but should start to cool off, as energy decrease accelerates.
I am starting to think of how big an effect this will have in 2012. The biggest long term effect is going to come a rise in sea level. That rise comes from ice that has been stored on land, suddenly gets added to the ocean. The ice can remain frozen for the most part - it only needs to move from the land to the sea. The iceberg could take another 3 years to melt, but the rise in water happens almost instantaneously.
If the temperature over Greenland hits a 100 F even for a week, there will be a huge increase in the total water melted. What most people do not realize is that glaciers advance by the amount of water flowing under them. The water acts as a lubricant.
So if a third of Greenland ice ends up in the ocean, we could see a foot rise in ocean within a few weeks. I wonder where the millions in Miami will move to?
