Given the exceptionally warm and early spring we are having here in the eastern US, following a very mild winter, I was curious to know whether it was globally very warm. I checked the NOAA State of the Climate report for February and the map above tells the story: it's remarkably warm across much of the US and the North Atlantic into the UK, and also in northern Siberia, but it's exceptionally cold in much of continental Europe and Asia. Overall, it's not a particularly warm February by the standards of the last couple of decades:
So this spring is more an unusual distribution of warmth and cold, rather than a global warmth anomaly. (Although worth noting that it would be a record-breaking warm February globally had it occurred any time between 1880-1970).
