May 2023: Global Temperatures

I make May the 4th warmest May in my DIYDIY Do It Yourself series that started in 1948. Its tight at the top, but May 2016 is still fractionally higher.

Global mean temperatures have started to show a bit more consistency in their rate of warming over the last month or so.
