No no don’t go away, there’s actually some science in this post, courtesy of the increasingly-heavyweight Nick Stokes. Or, perhaps more fairly, whatever science there is comes from NS. But there’s a lot of snark too, as I hope you’d expect. That comes from me. The title isn’t quite right; I could have tried anopsologists but I bet you wouldn’t have recognised that – I wouldn’t have, until I looked it up. But let me attempt to come to the point. Over at JoNova is yet another of those tedious posts where they complain that a weather station has been “adjusted” to show warming (and they’re still gnawing on the same dry bone), and that one should only ever eat raw data because only raw data is good for you. If you find raw “skepticism” too raw, you could try the WUWT echo chamber which, errm, just echoes JoNova.
In this case the station in question is Amberly, and if you care about what’s actually gone on then you should of course read Nick Stokes and if that isn’t enough you could read part 2. Nick also has a convenient post showing the affects of adjustment on trends, which is reasonably convenient for pushing at people who claim (without bothering to check, obviously) that adjustments always push the trends upwards. Or this one.
JoNova has a “home crowd” who can be relied on to say the right things, much like some of the WUWT regulars. Here’s one saying the artificial concept of homogenisation (which literally means removing all difference), is an act of unthinking vandalism which is probably typical enough; I don’t think I’ll bother quote any more. What’s unfortunately-not-at-all-surprising in this case is that they’re all mouthing off without having bothered to do even the most basic of checks. Is there good metadata for this station, to rule out a move or other change that might justify an adjustment? No. Is that the Bureau Of Meteorology’s fault? Not really; the station was run by the RAAF when the “move” occurred. That doesn’t stop some of the commentators there actually literally accusing the BoM of criminal behaviour.
Trivia: Evan Jones makes a cameo appearance, saying “I hate and despise homogenization with an ice-cold passion” which is jolly fun, but he doesn’t tell us why. But it sounds like he’s a fruitarian.
