Khebab - nice charts. It looks like the trend of ice loss starts around 1950. It is also curious that the one area on Earth where temperatures seem to be lower now than in the past is around the Bering Sea, and yet sea ice is still being lost to the N of this cool spot.

Did you know that the arctic ice drifts continuously like a conveyer belt. This was used by Nansen in his 1893 to 1896 expedition, using the polar exploration vessel Fram, as a lazy way to get to the north pole - see map.



The Fram Museum in Oslo is well worth a visit.

And to finnish with a picture of Nate in Wisconsin....


Whilst on topic, this clearly has little to do with peak oil - sorry Dave.

Very funny. Did my Mom send you that?
