Perennially Puzzled Bob Tisdale surfs the surface at Florida Keys

Update: For the benefit of new WUWT visitors, I wasn't banned from WUWT for troll behaviour. I was banned for being a "clueless female eco-nut", because of an innocuous tweet. (In four years I only made about 30 comments at WUWT, mostly polite and on topic.) Click here to read about it. I'm not alone. WUWT is intolerant of anyone who accepts science.

Also, don't fall for the typical paranoid conspiracy ideation you may have read at WUWT. 7DaBrooklynKnight7 has never been banned, and what he, not I, suggested was his parting comment is not lost forever, it was moved to where super-silly comments often go - to the HotWhoppery :)

Unlike WUWT, I rarely disappear comments completely and have had to ban very, very few people, and only then for extreme behaviour. Click here for the comment policy. (Also unlike WUWT, and the shameless double standards of it's various anonymice like the "Bob Tisdale's" of the world, I respect people's right to privacy and prefer to focus on the science.)

Perennially puzzled "Bob Tisdale" is a one trick pony. His trick is sea surface temperature. Or so he pretends. He's no climate expert. He's not a climate scientist. He's best known at WUWT for his dabbles in ENSO.

Today "Bob Tisdale" wrote an article at WUWT (archived here) that he claims disproves practically everything in a recent paper about coral reefs. Not just any corals, the paper was specifically about corals in Florida Keys. Thing is, Bob Tisdale didn't bother reading the paper much less try to understand it.

Bob has no excuse for not reading the paper. It's open access and you can read it here. The title of the paper is:


A Century of Ocean Warming on Florida Keys Coral Reefs: Historic In Situ Observations


It was reporting research done by scientists at the US Geological Survey and elsewhere with a team led by Florida-based marine biologist Ilsa Kuffner.

Bob wasn't interested in the paper. He wasn't interested in the fact that it was a report based on in situ observations. He probably isn't at all familiar with the reefs around Florida Keys. Just the same he took it on himself to decide that the research should have instead been about:

One Hundred and Forty Three Years of Gridded Sea Surface Temperature off the Coast of Florida using HadISST


Deniers toss out direct measurements, preferring homogenised estimates


Bob didn't want the scientists to use site-specific data, or temperature under the sea surface where the corals are. Data painstakingly collected from specific locations over decades, using thermometers, calibrated data loggers and precision thermographs.  Data carefully analysed by qualified experts over weeks or months. Without filling in gaps in data, and where the researchers discarded the small amount of data that couldn't be corroborated.

That sounds like just what deniers clamour for, doesn't it. You'd think they'd be singing the praises of the researchers. Recall their horror at gaps in climate data being infilled by estimates based on surrounding regions. Recall the perennial protests from deniers at climate data being homogenised to correct for calibration errors, station moves, breaks in the data.

Not this time though. Nope. This time they want massaged, combined, "manipulated" data estimated from multiple sources. Bob Tisdale didn't want a bar of actual direct observations using thermometers and precise measuring instruments on site. Instead Bob trotted off to KNMI Climate Explorer and got different data. He preferred gridded data estimated from combining observations from ships, from buoys, from satellites, with data gaps filled by interpolation. He wasn't interested in the temperature changes of the coral reefs themselves. He was only interested in the temperature of the thin skin of the sea surface - averaged over a wide area well beyond the corals the scientists were researching. Yet leaving out some of the area that the researchers did cover.

Bob spent a few minutes plotting HadISST surface temperatures of the ocean far afield. He then triumphantly pronounced the months of dedicated detailed scientific research about coral reefs in Florida Keys was dead in the sea water (so to speak).

But it's Bob who is wrong and woefully so.

(This article is very long. If you're on the home page click the read more to see what the paper is about and the reaction of the fake sceptics and resident pseudo-science disinformer, Bob Tisdale, at WUWT.)
