UPDATE: Breakup has occurred! See below, for my timelapse video
Here is the webcam closeup – when it was still standing as of 14:18 AKDT:
Alaska Dispatch confirms what we already knew in this thread on WUWT:
Like a striped testament to one of the coldest winters to hit Alaska in 100 years, a black-and-white tripod remains upright, atop stubborn Tanana River ice in Nenana. At 12:42 (ADT) Monday afternoon, the still-frozen waters allowed Nenana Ice Classic set a new record for the latest the ice has gone out in the 97 years since railroad workers started keeping track.
If you look on the Nenana Ice Classic website, you might think the record was broken an hour earlier, but the ice-out times listed there are in Alaska Standard Time. So the old record, listed as 11:41 a.m. (AST) is actually 12:41 p.m. Alaska Daylight Time (ADT).
Geophysicist Martin Jeffries at the University of Alaska, Fairbanks said in 2008,
Wall Street Journal – March 7, 2008
Climate Watchers Place Own Big Bet On Alaska’s Thaw
The Ice Classic has given them a rare, reliable climate history that has documented to the minute the onset of the annual thaw as it shifted across 91 years. By this measure, spring comes to central Alaska 10 days earlier than in 1960, said geophysicist Martin Jeffries at the University of Alaska, Fairbanks — and that trend is accelerating. “The Nenana Ice Classic is a pretty good proxy for climate change in the 20th century,” Dr. Jeffries said.
The local ice lottery is further evidence of a long warming trend affecting lakes and rivers throughout the Northern Hemisphere, reported by University of Wisconsin researchers who analyzed newspaper archives, transport ledgers and religious records dating back to the 16th century……….
I wonder what he says now?
UPDATE: 4:43 PM Pacific time (15:43 AKDT), the tripod apepars to have flipped over and sunk as the breakup is now underway. I won’t be able to show this until a couple hours from now when I get home and pull up the series of time lapse captures from my PC running there. Look for a Movie to be uploaded tonight or tomorrow – Anthony
