Meteorological spring is March to May. (*In the Northern Hemisphere.)
The Hadley Central England Temperature (HadCET) just had the warmest meteorological spring in its 367-year history.
(OK, it's really only 303 years, because some of those early years had temperatures taken inside buildings, etc., not in a systematic fashion, but can you really blame them for trying?)
But still, 303 years. That's pretty impressive.
And this year's March-April-May average saw the warmest temperature anomaly in that little region, 2.26°C, which was the same as last year's value, exactly.
Baseline is 1901-2000.
Still, this year's year-to-date average only ranks 11th highest in all those years.
But things are cooking.
The 10-year moving average for HadCET is at a maximum, 0.52°C higher than 10 years (120 months) ago.
The 50-year linear trend is an impressive 0.31°C/decade.
But it's just a little region in England.
