Warning. Link to WUWT follows.
New paper: A high-resolution surface mass balance map of Antarctica shows “no significant trend in the 1979–2010 ice sheet”
The paper says:
"The estimated SMB trend, integrated over the ice sheet, equals -3+-2 Gt y^-2."
Anthony Watts says:
"The estimated SMB trend, integrated over the ice sheet, equals 3+/-2 Gt/y^-2"
Can you spot the difference?
A trivial error you might say. He's just missed off the minus sign while pasting! But this is the kind of error Anthony would jump on if a scientist had done it. He would say something like:
It's only a typo, but it does raise troublesome questions about the quality control in place before publication! And his commenters would no doubt nod their heads and wonder if the error was deliberate. Why do all these errors only happen in one direction?, they might ask.
Anyway this isn't actually the worse (let alone the only) error Watts makes in this post. He thinks this paper shows that the Antarctic ice sheet is not losing mass:
"Uh, oh. Another talking point bites the dust."
"While Gore, Hansen, Branson, and a gaggle of hangers on just finished a publicity stunt tour of Antarctica to tell us all how terrible the ice loss is there, the data says otherwise. No trend!"
Embarrassing for Watts (or at least it should be) the paper doesn't show this at all. It doesn't address the issue of whether Antarctic is losing ice, because it's about surface mass balance, not the mass balance of the entire ice sheet.
Now I didn't know that, I've never heard of surface mass balance before. The difference is though that I have a faint clue what is happening with Antarctic ice and a faint idea about how science generally works so I can kind of weigh up the right level of skepticism and belief to have at these kind of results. This is the kind of thing that is in my head about antarctic mass balance:

The paper doesn't fit that. So I would be skeptical about the paper, or rather my interpretation of it. At that point I would spot the numbers in the paper and would like to think that would lead me to realizing the "surface" in "surface mass balance" was a game changer.
But where does Anthony go wrong then? Well I suspect he's been most successful in preventing inconvenient facts getting anywhere near his brain. He probably hasn't even seen that image above, or the
similar one in AR4. He also probably thinks science is overturned on a whim by a new paper. You know, all those papers above showing the Antarctic is losing mass and Anthony is perhaps the kind of guy to think one paper showing otherwise overturns the lot -
even if especially if it's published in something like Energy and Environment.
But wait there's more. Lets look at that title again.
I'll highlight the relevant parts:
"A new, high-resolution surface mass balance map of Antarctica (1979–2010) based on regional atmospheric climate modeling"
Wait what? Based on climate modeling..? Anthony citing climate models as evidence? Whats Up With That? Isn't he usually a stickler for observations, not models? I am not certain but I even think there is an old WUWT post trying to pour doubt on the observational GRACE measurements of ice sheet mass balance.
This episode strongly suggests that Anthony judges results not on their evidence but on whether he likes the result. In this case he didn't even show a shred of doubt about the paper's results. It would have been very different if the same modeling paper had shown a large decline. I bet we'd have got a very different WUWT take on the paper in that case.
So we have in one WUWT post:
Now that alone is just incompetence. But it's the rest that makes me sick:
- Hypocrisy. Using evidence based on models to overturn observations.
Hypocrisy. WUWT chastises others for lesser errors. If skepticalscience or realclimate, let alone a climate scientist, had made all these errors in one post WUWT would viciously attack them and the comments would be filled with suggestions that the error was deliberate.
Arrogance. They attack people more competent at them for lesser errors, even while they make a bundle themselves. Then they spend half their time lecturing others on how to do it properly.
- No corrections made to the post despite all the errors being pointed out in the comments. More hypocrisy because WUWT regularly bemoans uncorrected errors.
It's worth ending with the first comment on the post just to highlight how Anthony's errors inevitably enter a canon of BS for certain folk:
"I look forward to the BBC giving this the same amount of hype that Steig et al 2009 received… I shall not hold my breath though."
