The sea ice off Iceland reveals an extraordinary growth in severity, from zero coverage before the year 1200 to eight - week average cover in the 13th century, rising to 40 weeks in the 19th century, and dropping again to eight weeks in the 20th century.
Sea ice coverage in the fjord ranges from thicker, white ice seen in the background, to thinner grease ice and leads showing open ocean water in the foreground.
If you'll recall from my previous post, polar bears seem to have barely survived the extensive sea ice coverage during the Last Glacial Maximum — in other words, too much ice (even over the short term) is their biggest threat.
Antarctic sea ice coverage is slightly above average and the growth varies from one part of Antarctica to another.
BBC News reports that data from Europe's Cryosat spacecraft shows that Arctic sea ice coverage was nearly 9,000 cubic kilometers (2,100 cubic miles) by the end of this year's melting season, up from about 6,000 cubic kilometers (1,400 cubic miles) during the same time last year.
To make use of that potential we would need good estimates of sea ice thickness, such as might be obtained from ICESat or CryoSat (i.e., complete spatial coverage).
The SH sea ice data are reliable since 1979, but suffer from poor observational coverage before 1979, and revert to climatology before 1974.
The separation in REA16 of the effect of masking from that of sea ice changes on blending air and water temperature changes is somewhat artificial, since HadCRUT4 has limited coverage in areas where sea ice occurs.
