Here’s what global warming looks like month by month for 137 years

The context: 2017 was the third-warmest year on record, and the seven warmest years have occurred since 2010. This chart shows temperature anomalies — which is a departure from an average long-term baseline temperature — for every month since January 1880, compared to the average temperature between the years 1901 and 2000. The data is constructed from thousands of available, quality-controlled land and sea surface temperature readings across the world, and runs through May 2018.
