“Open Letter to Jon Stewart – The Daily Show” (2014-01-17). I LOVE these denialist “open letters”! Anthony Watts seems to love ‘em too, but for different reasons. Anthony loves the chance to act as if he’s initiating a great public debate. When The Letter lands like a tiny pebble in a reeeeeally deep well he can pretend it was so beautifully argued that the (oblivious) target was shamed into silence. Me? I love the hubris.
Here we have Bob Tisdale lecturing Jon Stewart about his coverage of right-wing “weather!” whoppers on January 6th. Anthony Watts has had a pickle up his ass on the same topic; the recent deep cold snap should have been the final nail in the Global Warming hoax, right? But at least weatherman Anthony learned what the Polar Vortex is.
Bob lists his credentials up front so that Jon will sit up and take notice. He’s an ”independent climate researcher” (code for “not a climate researcher”) and author of three ebooks!
Like most denialists, Bob seems to consider himself a blend of Galileo and Martin Luther. Fierce intellect, incredible moral integrity, and probably the strength of ten men. Yeah, right. Bob’s just rattling through the usual tired and debunked denialist claims, misrepresenting evidence, demonstrating his ignorance of real scientific process or squawking “the models are wrong!”
I note that Anthony seems A-OK with the anti-Semitic undercurrent in his carefully moderated comments sandbox. Did you know Jon Stewart’s real surname is Leibowitz? This is apparently important to know.
“The GISS divergence problem: Ocean Heat Content“. Butter wouldn’t melt in citizen-scientist Bob Tisdale’s mouth, would it? He’s back with new proof that there’s no global warming and that them gubmint scientists is stupid. Anthony Watts approvingly notes the alleged “[denialist] reality versus [Goddard Institute for Space Studies] projection disparity” and declares “a GISS miss by a country mile.” Game over, yuck, yuck, yuck!
Tisdale’s claim is that Ocean Heat Content (OHC) hasn’t risen as fast as an old GISS model projected (note that this was not a prediction). Why? Well, because he can slap a projected straight line (Bob still loves ‘em) on a chart that rises faster than the observations. Therefore, warmists are liars and their computers are too. This handily side-steps the real issue: Ocean Heat Content is unquestionably rising. We call this global warming.
Except… Even Anthony has to give Bob a nudge in the comments for failing to admit that his citizen-science fair project is showing “anomalies” i.e. deviations from the trend and not the trend itself. Sure, the target man on the street won’t spot it, but it’s like plastering “kick me” all over your own back for the benefit of informed scientific observers like Tamino, to whom Bob’s posts are like candy to a baby. Tamino indulges his sweet tooth in Favorite Denier Tricks, or How to Hide the Incline.
So how does Tisdale think he’s proven that the alarmist GISS projection of increasing OHC doesn’t match the measured increase? By using the classic denialist trick of showing the projection over a very particularly chosen time period from on a very particularly chosen point. This allows him to imply that OHC is flat but the GISS projection is increasingly divergent from “reality”. Anthony is silent on the this half of Bob’s deception because in the denialist playbook cherry-picking is enthusiastically endorsed.
Bob is trying to dispute the claim by meteorologist Jeff Masters that the recent Midwest deluge [was] enhanced by near-record Gulf of Mexico sea surface temperatures. Although Jeff is talking about weather, Bob Tisdale recognizes the threat. This might mean that global warming really is happening! Of course it’s not, so he accuses Jeff of a ”contrived” claim and counters that “…over the past 80 years, there is no global warming signal in the Gulf of Mexico SST data.”
My blue trend is just eyeballing but it's a lot less contrived than Bob Tisdale's flat red line in this example from his "analysis".
Unfortunately for Bob any open-eyed reader will see that every chart he tries to use as evidence reveals that he has deliberately picked dishonest comparison points that minimize the increase and he has ignored everything in-between. Details, details.
Statistics, Bob. Look into ‘em. There’s a reason scientists use ‘em.
