The recent surge in temperatures across Europe in January can be seen in a sharp rise in estimated mean temperatures across the northern extratropics in the daily anomaly chart for the last year. The surge seems to have started shortly before Christmas in my DIYDIY Do It Yourself global series, and is still going on in around that zonal region, with anomalies now around 1.2°C higher than the 1991-2020 LTALTA Long Term Average. This is usually defined as a 30 year period by the WMO.. The effects of the North American cold wave and the cold snap across Europe are also visible as a blue down spike at the very end of November.
