Followup, 6PM: photo and video here, neither very high quality, but still intriguing. Here's how I think Climate change is implicated: from Wikipedia on The Blob (movie), "The film closes with a scene of a military plane dropping the Blob into an Arctic landscape. The film ends with the words "The End", which then morph into a question mark..." I always suspected that dumping the blob onto the icecap was a bad idea. Now, with the ice melting down, and Steve McQueen no longer around to help, it's on the rampage again, and we're in a world of hurt.
Followup, Fri. July 17: It's algae.
