Last time, I did some comparisons between HadSST4 (unadjusted data) and the output from the simple gridder. They were pretty close to each other. I ended up by showing that the number of occupied gridcells started to diverge around 2004 as they started plunking Argo floats in the ocean. So, the next step is to […]| Diagram Monkey
Yesterday, I posted the results from a very basic gridder. Today, I’ve been processing some more data, tidying up the code a bit, looking at the output and doing some initial comparisons. There’s a jupyter notebook here with the details. Code tidying involved rearranging things a little bit, replacing the masses of copy-pasted code from […]| Diagram Monkey

Google scholar still seems to be working. It offered me a thesis by Vikrant Sapkota of Penn State University on Leveraging Historical Observational Data and Climate Models to Understand Uncertainti…| Diagram Monkey
It has been a while since I looked at the merging of global temperature datasets and even longer since I wrote anything up. I have been thinking about it which doesn’t, as with all my thinkin…| Diagram Monkey
When I became a climate scientist nearly 22 years ago, I started accumulating books on the subject. One of the first was called something1 like “Global Warming: Apocalypse or Hot Air?” …| Diagram Monkey

Out there, somewhere in the wilds, computer programmes are learning to manipulate people. They’ve been doing it for years of course, but they’re getting good at it now. Open AI had one …| Diagram Monkey
Consequential Differences in Satellite-Era Sea Surface Temperature Trends Across Datasets is a neat little paper looking at – and here I risk a good deal of redundancy1 – differences in…| Diagram Monkey

Is there a better way to combine global temperature datasets?| Diagram Monkey
I’ve been staring intently at this diagram (from Evidence for a limit to human lifespan) for a while now, particularly panel b. Panel b shows linear regressions of the logarithm of the number…| Diagram Monkey
I spent a little more time looking at the data from the paper on “Evidence for a limit to human lifespan”. This figure is the result. The data are available upon registration from (a) s…| Diagram Monkey
This is a slight departure, being a sort of review of (grumble about) a paper that appeared in Nature recently (Evidence for a limit to human lifespan) but is not at all related to weathe…| Diagram Monkey
This year, 2023, global average temperature has done some unexpected things. Naturally, people want to know why and, also naturally, a certain group of people wants to tell them. The first definiti…| Diagram Monkey
