| The
amount
of sea-ice changes dramatically throughout the year. Click this picture for a movie of how Arctic sea-ice has changed between 1979 and 2004.  |
The maximum
of Arctic sea-ice is in late winter (February). Click
the map to see the sea-ice in
each February since 1970 (and how it may look in the future).  |
The
minimum
of Arctic sea-ice is in late summer (September). Click
the map to see the sea-ice in each
September since 1970 (and how it may look in the future).  |
Climate
models show that, due to extra carbon dioxide in the atmosphere, arctic
surface air temperatures may rise 7 deg C by the year 2100.
If we give the model this warming, see what happens to the
Arctic sea-ice. Click on

sea-ice extent.
