Global Warming not to blame for toad extinction

Global Warming not to blame for toad extinction“. Anthony Watts tries to present a Columbia University press release as disproof of the claim that global warming drove the extinction of Costa Rica’s Monteverde golden toad. The paper’s disputed conclusion is actually that drying due to El Niño weather patterns allowed a harmful chytrid fungus to spread into the toad’s habitat.

The press release says that “proving a link between climate change and biodiversity loss is difficult because so many overlapping factors may be at play, including habitat destruction, introduction of disease, pollution and normal weather variability.” Not too difficult for Anthony to disprove though.

Scientists Locate Apparent Hydrothermal Vents off Antarctica

Scientists Locate Apparent Hydrothermal Vents off Antarctica“. Anthony Watts reprints this interesting Columbia University report so he can imply that this discovery somehow explains why the Antarctic is losing ice mass. It’s not man-made after-all! Whew.

Hydrothermal vents occur at tectonic plate boundaries. There aren’t any such zones underneath or along the coasts of Antarctica. Even if there are hydrothermal vents where Anthony wants them, such vents are oceanographically speaking insignificant point sources of heat. Go back to the wishful thinking/goofy idea cupboard and try again.

See any hydrothermal sites in Antarctica?

CRUTEM3 “…code did not adhere to standards one might find in professional software engineering”

CRUTEM3 “…code did not adhere to standards one might find in professional software engineering”. John Graham-Cumming, a British computer programmer, says that the University of East Anglia’s Climate Research Unit global temperature analysis programming code isn’t professional. Anthony Watts concludes that this is damning expert opinion.

Sorry John but CRUTEM3, just one of several tools for analyzing global temperature, is scientific code. Done on a tight academic budget, it was basically a one-off effort. Could it be improved? Sure. Is the programming “quality” relevant? Not fundamentally. Does it give a correct result? Apparently. Good work spotting minor errors, but we’re not debating the elegance or efficiency of internet routing protocols here.

Corrections resulting from John's error-spotting in green.

Just as an aside, the fuss over the quote-mined code fragments that were found in the stolen CRU e-mails was about code that wasn’t actually used.

A new paper comparing NCDC rural and urban US surface temperature data

A new paper comparing NCDC rural and urban US surface temperature data“. Anthony Watts reports that the denialist “think tank” Science and Public Policy has “published a paper” by retired NASA “advanced materials” physicist and self-described extremely conservative blogger Dr. Edward Long. “Published” in the sense of printed, just like Anthony’s own discredited Science and Public Policy pamphletSurface Temperature Records: Policy Driven Deception?” (tellingly admired by Dr. Long). Actually, this feels like a do-over of Anthony’s idea with a Ph.D. stuck on top and the really dumb bits left out.

Contiguous U.S. Temperature Trends Using NCDC Raw and Adjusted Data for One-Per-State Rural and Urban Station Sets concludes that the NCDC (National Climatic Data Center) has “taken liberty to alter the actual rural measured values.” Why? Because two 48 station subsets (“rural” and “urban”) have the same trend after the NCDC’s adjustments have been made. Which means that some nefarious trick has forced them to match. Dr. Long selected his stations “on the assumption that within a certain latitude band stations along an East-West line experience the same climate and that within a grid unit the set of stations are somehow related“. That’s a rather off-hand justification for what I suspect is a pretty careful cherry-picking operation. There have been objective re-examinations of the US surface temperature data (Menne et al, 2010), but no significant errors have been uncovered.

Dr. Long also tries to wave away the temperature trend by suggesting that it reflects population growth around the weather stations. Somehow population growth intensifies the UHI effect. I’m not a climate scientist but I would expect the same UHI effect to occur more widely with population growth, not show up as ever “hotter” readings. After all, UHI is effectively a landscape factor, something Anthony himself has been fixated on for sometime on his surfacestations.org project. Should someone whisper maybe it’s global warming?

WMO: “. . . we cannot at this time conclusively identify anthropogenic signals in past tropical cyclone data.

WMO: “. . . we cannot at this time conclusively identify anthropogenic signals in past tropical cyclone data.” Anthony Watts considers this recent report by The World Meteorological Organization a “stunning statement” about the frequency of cyclones. They haven’t increased statistically, so there’s no global warming! Anthony found this on right-wing political scientist (and self-proclaimed “honest broker”) Roger Pielke Jr.’s blog.

Actually, among other things the authors say “it remains uncertain whether past changes in tropical cyclone frequency have exceeded the variability expected through natural causes.” Emphasis mine. Not quite so stunning. More like scientifically honest, in fact.

This is the kind of “weather not climate” data that denialists love to talk up. It’s a low volume but variable record that is easily misrepresented. They can also count on honest scientists making the usual statistical cautionary statements, which can then be used against them (see Pielke’s blog in general).

However, I think that global warming is actually predicted to increase the intensity of cyclones, not the frequency. I also like how Anthony unselfconsciously posts a chart showing that ocean temperature has been unequivocally going up! Hey, Anthony! Shhhhhh…

Setting the Record Straight on the IPCC WG II Fourth Assessment Report

Setting the Record Straight on the IPCC WG II Fourth Assessment Report“. Right-wing partisan economist Indur M. Goklany is annoyed with Professor Martin Parry’s interview in Nature for failing to talk about what Indur M. Goklany wants him to talk about.

Goklany has yet to meet a nit that he can resist picking. The gist of his complaint seems to be the misdirection of we must solve every other human problem before we do anything about climate change.
