We are all aware that Arctic ice extent has increased over the last two months, and is now about one million km2 larger than it was in 2007. But where has the ice growth occurred? I generated an image which makes this easy to visualize.
In the composite image I prepared below, green colors represent 2010 ice that was not present in 2007, and red colors show where 2007 ice existed on this date but is not currently present.
A couple of interesting items.
- There is excess ice in the Baltic Sea, due to the cold winter there.
- There has been a lot of cold air over the Bering Sea and Sea of Okhotsk (as seen below) causing excess ice on the Pacific side.
