The Northern Hemisphere Sea Ice coverage
Ice concentration higher than 30% are classified as ice:
Sea ice extent in recent years (in million km2) for the northern hemisphere, as a
function of date.
Please notice, that the sea ice extent in this plot is calculated with the coastal zones masked out. To see the absolute extent, go to this page.
