Yeah, yeah, this is anecdotal.  But we keep getting anecdotal evidence.  After a while, it adds up.

Quotes from 1,000 Trapped on Ferry Stuck in Baltic Sea Ice:

A total of about 50 ships were stuck in ice along Sweden’s eastern seaboard

As soon as they break the ice, it freezes over again

Heavy ice cover is not uncommon further north, but the ice rarely gets thick enough in the Stockholm archipelago to trap powerful passenger ferries

Ice breakers were trying to free the ferry Amorella and two cargo ships stuck at the edge of an archipelago northeast of Stockholm, while rescue helicopters and military hovercraft were on standby to evacuate passengers if needed. Gale-force winds were hampering the effort

Calling Al Gore.  We need some hot air over there . . .
