Anthony Watts has another "Claim" headline (archived here). This time it's a claim that Arctic sea ice is forming later and melting sooner - as a general trend. (Anthony copied and pasted a long article with no attribution for the article and no link to any source. He didn't mention the research paper itself.) Here are the opening paragraphs from the NASA press release:
The length of the melt season for Arctic sea ice is growing by several days each decade, and an earlier start to the melt season is allowing the Arctic Ocean to absorb enough additional solar radiation in some places to melt as much as four feet of the Arctic ice cap’s thickness, according to a new study by National Snow and Ice Data Center (NSIDC) and NASA researchers.
Arctic sea ice has been in sharp decline during the last four decades. The sea ice cover is shrinking and thinning, making scientists think an ice-free Arctic Ocean during the summer might be reached this century. The seven lowest September sea ice extents in the satellite record have all occurred in the past seven years.
"The Arctic is warming and this is causing the melt season to last longer," said Julienne Stroeve, a senior scientist at NSIDC, Boulder and lead author of the new study, which has been accepted for publication in Geophysical Research Letters. "The lengthening of the melt season is allowing for more of the sun’s energy to get stored in the ocean and increase ice melt during the summer, overall weakening the sea ice cover."
The fact that the melt season is getting longer won't be a surprise to anyone. However Anthony Watts dismissed the analysis because:
I tend to take research done by Ms. Stroeve with a grain of skepticism, since she allows her work to be aided by political activists at Greenpeace.

Here is Anthony Watts hoping that the greenhouse effect will be disproven one of these days:
While there likely is some truth in the report, what isn’t explored is whether the cause of this change is part of a natural cycle, a natural cycle enhanced by some AGW effects, or purely an artifact of AGW.
The increases in surface ocean temperatures, combined with a warming Arctic atmosphere due to climate change, explain the delayed freeze up in the fall.
…reads like something Greenpeace would write, providing no other possibility. One thing I tend to notice about Earthly geological and atmospheric processes is that they tend to act on timespans than exceed human lifetimes, sometimes being orders of magnitudes longer. In the case of Arctic sea ice, a record going back to 1979 is shorter than that and only represent a fraction of what may be a natural cycle. Making claims that they know exactly what the cause is might very well bite them in a few years or few decades.
What other possibility would Anthony entertain? Leprechauns? Magic? He thinks that Arctic warming in the context of global warming might be "natural"? That the greenhouse effect has suddenly stopped working?
Notice his "tend to notice" that "Earthly geological and atmospheric processes" act on timespans that exceed human lifetimes. Sometimes being orders of magnitudes longer!
Wow - really, Anthony? What a revelation that will be to all the world's geologists.
Yeah. It's a huge ask to expect a science denier to think in timeframes longer than their personal life span.
Since Anthony can take Dr Stroeve's research, and by association anything that comes out of the NSIDC, with his "grain of skepticism", I expect that means he's letting the world know that we can take anything he writes with a huge dollop of disdain. He has a long association with the ignominious Heartland Institute and gets a lot of his material courtesy of people like the award winning climate disinformer Marc Morano.
From the WUWT comments
Sorry, I'm still strapped for time. You can read them archived here. I notice that Anthony is trying to retrieve his shattered reputation. Fat chance, Anthony! And he's playing the persecuted martyr into the bargain. Cheeky, given his propensity to round up a lynch mob to attack climate scientists and others.
