Recent global surface temperatures have continued to fall in the two years following the El Niño of 2014-16. January 2018 was the coldest January since 2014 in both the CRUTEM and GISS series (fig 1). The anomalies of 0.553°C and 0.78°C above the long-term average still mean that the global picture is one of various shades of yellow and red rather than blue though (fig 2). There was an interesting cold pool across a large area surrounding the Mediterranean during the month, but apart from this it was the scale of the warmth across eastern north America and northern Asia that were the main talking points.
If you were wondering just how the recent SSW has affected things, and how temperature anomalies ended up in February, here’s a chart that I’ve put together using reanalysis data (fig 3).
