Sea Ice

Arctic Sea Ice

Based on data from satellite radar altimetry collected in the period 2002 - 2008 one can see that rather dramatic changes took place in sea ice thickness. It is getting seriously thinner this year. Last year were exceptionally warm and it might be a late effect of that that causes the ice to diminish, but further studies are necessary to fully understand what is going on and what causes the changes.

Today the first snow covers the landscape in the Oslo region. It doesn't feel like it is getting warmer, I can tell you that! :-)
