Our favorite climate de-crocker, Peter Sinclair has a new video on the Arctic:
Here is a discussion of Barber’s peer-reviewed research: Where on Earth is it unusually warm? Greenland and the Arctic Ocean, which is full of rotten ice: New study supports finding that “the amount of [multi-year] sea ice in the northern hemisphere was the lowest on record in 2009″

This just came over the wire -
WASHINGTON – Tens of thousands of walruses have come ashore in northwest Alaska because the sea ice they normally rest on has melted.
Federal scientists say this massive move to shore by walruses is unusual in the United States. But it has happened at least twice before, in 2007 and 2009. In those years Arctic sea ice also was at or near record low levels.
The walruses “stretch out for one mile or more. This is just packed shoulder-to-shoulder,” U.S. Geological Survey biologist Anthony Fischbach said in a telephone interview from Alaska. He estimated their number at tens of thousands.

Colorado Bob,
Stay tuned, I’ll be treating the walrus story in an upcoming vid.
Wow, great video.
Pete’s stuff tends to be bloody good, to put it mildly! Kudos to the man.
Cheers – John
Peter… you should be ready to do a mash-up of all this great stuff for a documentary. You get right to the point.
@2 Don’t forget to include that they’re all AL GORE and a bunch of SOCIALISTS dressed up in costumes!!!!(snarkle,snorkle)
Well done!!!
CryoSat-2 data pretty soon:

Pretty soon we’ll know when the Arctic Death Spiral will finish.
Probably before 2020.

Another great video! Continuing with what this will mean is a great next step. Not only is this a big positive feedback due to loss of albedo, but Hansen and others feel that this could generate immense storms.
How will additional immense storms be generated from increased open water during the summer and early fall? What is the mechanism of this? What areas could be most affected?
I invite Peter or anyone else to answer these questions – Thank You!
You know what I’d like to see? I’d like to see someone pay for Anthony Watts to take an arctic excursion with Dr Barber. And film it.

Oh my god. great video, but global warming it is really a problem to our civilization, and planet.
Thank you people. A witty reminder. Nice choice of the happy go lucky looney tune.
Can’t wait to see the more precise data from CryoSat-2 for some last (foregone) hope that Arctic sea ice is going to stay with us at least through the summer somehow in the coming decade.
But for those of us intend on staying sane and alive for another 30-40 years it would be great to know how accurate is the idea of “time lag” in global temperature response to contemporary CO2 concentration. It matters a lot if it’s either one or three or four decades because of the ammount the world is spewing out at present. If we are now loosing the Arctic to, say, 360-70ppm of CO2 and “stabilisation” will happen at best between 450-500ppm is it time to prepare for …. overdraft of ocean currents?
Could someone knowledgeable direct me to some (non-subscription recources) for “climate time lag” and new ocean circulation when the Arctic is seasonally ice free. Thank you

John Cook and a host of helpers have put together an incredible resource of material.
Thank you Rob Honneycut . Nice resource with all the hyperlinks to real science papers.
If ice melt occurs, it breaks up and floats outward. During the polar winter these outflows form the 1-year ice but will further decline with proceeding of the process.
The question at this point is, can the process be reversed?
The extra energy intake from lost albedo has to be accounted for in form of more aggressive action to reduce anthropogenic greenhouse emissions. If not we will see profound temperature spikes – possibly in this decade.
Like a domino chain reaction this will likely trigger the methane release of the entire region.
