Five months into this meteorological year, the ten Weather Stations I’ve chosen to stand as a proxy for Global Mean Temperatures are showing a rise of 0.33°C above the 2008/9 to 2017/18 average. (Add 0.85°C to get my notional “above Pre-Industrial” figure.)
April was much cooler than March in the Northern Hemisphere but a little warmer in the south. You don’t really need a graph to visualise the sharp rise in both hemispheres from December to January and the rather gentle peaks and troughs since then.
I’m still checking my data tables for errors but the way I’ve set them up makes it quick and easy to add up the number of days that are as warm or warmer than the day before. This is more a fun thing to do and the results shouldn’t be taken seriously.
The northern hemisphere dip of 0.06°C from March to April has no effect on this “warmer days” lark. For now, though, it does look as if the Grand Solar Minimum is a thing of the future. Once it begins to bite, a graph like this will surely indicate that it’s downhill all the way, for who knows how long.
