St. Pierre and Miquelon Island
I lust like this graph.
We have a dandy example of a “bullseye” in 1992 and a “coincident” pivot. It’s a great example of taking a down trend and clipping the bottom peaks at less than -2.5 (notice they were regularly near -3 C before the change in 1992 and well below before the 1980 changes) while the top peaks are left dancing along that +3 to the occasional +3.5 C range.
Then the sun takes a nap in 2000 and the best laid plans have gone awry… Saint Pierre just can’t get it up… above zero… since. Sigh. Anyone got a “little blue pill” for Saint Pierre?
All that effort, and we’re still 1 C below when the series starts ( though about 1 C above the GIStemp “baseline”; so NASA GISS will call this a very hot +1 C Hair On Fire warming…)
Looks very unlike the smoothly rising trend, with gradual topping out, that one would expect from the CO2 thesis. CO2 has decreasing infrared blocking efficiency as concentrations rise to ‘near perfect’ blocksing. Basically, things ought to rise fast then start to flatten. Instead we have a drop with a “pivot” right when the processing applied to the data changes.
Yeah, I’d call it “human caused”, but not warming…
