It was cold in the 1930s, really it was (compared to now)

There's little if any quality control at WUWT. Blog-owner Anthony Watts doesn't have what it takes to do the job, according to his friend Willis Eschenbach. And I'm inclined to agree with Willis, which makes a change, since I don't often agree with him.

Today there's an unsophisticated article that Anthony's posted (archived here). It's by someone I've not come across before to my knowledge, Sheldon Walker. Sheldon is wanting to tell WUWT readers about the change in trends in global mean surface temperature since records began.

ICYMI - there's no stopping the rise in surface temperature!

In case you missed it (ICYMI), a couple of new papers have been published recently, demonstrating that there has not been any "pause" or "hiatus" in surface temperature in recent years. Yes, the rate of increase wasn't as high as it has been in some other periods. However these papers demonstrate that there was nothing different from what can be expected from a warming trend with interannual variability imposed on it.


Change points of global temperature: Cahill, Rahmstorf and Parnell


If you're a fan of realclimate.org (the benchmark of world best practice in climate blogs), then you might remember the change point analysis written up there last December, by Stefan Rahmstorf. The article was called "Recent global warming trends: significant or paused or what?" This new work looks to be on the same topic written as a peer-reviewed paper in IOP Science: "Change points of global temperature". It's open access so you can read it at your leisure.
