All but two springs in the last 31 years have been mild and several of them very mild with anomalies close to +2°C

According to my method of calculating the first day of spring using accumulated mean temperatures, the first day of spring was thanks to a record very mild end to February, was over three weeks early on the 26th of February this year (2019). Not a record, but nonetheless very early and forcing the linear trend from 1772 down slightly steeper, so that springs on average are arriving 20 days earlier than they did 247 years ago.
