ERA5: smallest global anomaly for almost two years

This months anomaly of +0.44°C for August 2020 from the Copernicus ERA5 global reanalysis temperature series was the smallest in almost two years, and finally the 12 month moving average has begun to fallback after rising continually since the middle of 2018. Monthly mean anomalies have generally been falling since the peak of +0.80°C in February of this year. My own DIY daily global temperature series has been falling back since the end of February, and I thought that I had made a mistake in my calculations because its took almost six months for temperature anomalies to fall back in monthly global temperature series such as ERA5,

“Globally, it was the fourth warmest August on record; particularly above average over southwestern USA and northern Mexico, and over northwestern Siberia and much of the Arctic ocean. Air temperatures over the ocean were mostly above average, though in the Southern Hemisphere substantial regions were below average.”
