We’ve updated sea ice, so it’s time to have another look at the global temperature series I last updated nearly a year ago. Here’s the instrumental averages with another year on the traces. Ho-hum … still shooting up; still on track:
Global monthly temperatures since 1850
— instrumental estimates
Details are on the graph page. Until just a couple of years ago this kind of plot was pretty controversial; those looking to obfuscate would make all sorts of silly claims. That’s gone quiet now, coincident with the culmination of the Koch brothers’ highly amusing intervention. Instead we have endless touting of the so-called “pause”, which another year has rendered even tougher to perceive:
Global monthly temperatures since 1970
— instrumental estimates
As of now we’re right on that trend line. Interestingly, if we add the satellite and reanalysis series, we can see that one of the satellite records has actually ticked downwards a bit (that’s one of eight), but at the same time the reanalysis series I plot (pink dashes) has ticked upwards:
Again, details are on the graph pages (click the plots). Forensic month-by-month, series-by-series analysis is not very useful. Take a step back, and the view is obvious.
And, as I’ve pointed out before, if one simply extrapolates that polynomial trend, it neatly bisects the Intergovernmental Panel on Climate Change’s predictions for 2050. IPCC unrealistic? Not on a simple “common sense” viewing of the data:
