Sea Ice News – Call for Arctic sea-ice forecasts, plus forecast poll

Sea Ice News – Call for Arctic sea-ice forecasts, plus forecast poll (May 19, 2011). Pull the other one, Anthony Watts! I almost shot tea out of my nose reading Anthony’s blithe claim:

It has been awhile since I’ve done a sea-ice report. That said, not much of note has been going on in the sea-ice arena, we are in that time of year when all of the years converge into a tighter grouping.

I guess his stalwart bobble-heads were starting to need reassurance that Global Warming was still over. Unfortunately there are a few differing opinions out there:

Anthony even thought he could bluff his way past his own chart. Nice try. He does try to bury it among a busy collection of eye-glazing squiggles and bar charts.

Nothing to see here, says Anthony... My annotations in red.

It’s probably nothing*

It’s probably nothing*“. Anthony Watts tries to slide another stupid “Snow! Somewhere!” post by as just a little “humor“. Apparently busy denialist copy-and-paster Tom Nelson noted that there was lots (41 inches) of ice in Nenana, Alaska (which is in the Arctic you know) on April 21st this year. But the ice was all gone by that date in 1940! Therefore global cooling.

Nenana has held an annual draw to guess the date of spring breakup on the Tanana River for a century now, and this is Anthony’s new gold standard for global climate data.

Like most northern rivers, the Tanana’s spring ice breakup is almost entirely dependent on flow volume during the spring run-off. The ice broke up, at a thickness of 39″, just four days after this astonishing climate evidence was presented. Also at 64°N Nenana is below the Arctic Circle.

Willis Eschenbach accidentally undermines Anthony's "humor".

Anthony’s teammate Willis Eschenbach creates the real punchline by inserting a chart (above) that shows that ice break up on the Tanana River is clearly trending to earlier dates. Or maybe he just can’t understand his own work.

I guess Anthony’s readers aren’t subtle enough to follow Anthony’s attempt at humor; they’re reacting with stolid earnestness.
