I am fed up with waiting for HadCRUT to publish their global temperatures for February and March let alone April, so here is a spring snapshot of the worlds leading global temperature series. At least ERA5 have published their anomaly for April, which emphasises the twin peaks a little better. I don’t know what’s happened to the data for the UAH series for April, they are usually the first ones to publish. Global monthly temperatures are a bit like geological time, in that things happen only very slowly, and changes are slow, but the ‘twin peaks of the last eight years have made things a little more interesting. Logic dictates that the current downward oscillation in 12 month average global temperatures can’t go on forever, but will they flatten out or even pick up sharply before COP-26 in November, or is global warming on pause?
