The Last Four Years Have Been Earth's Warmest on Record

Earth had its fourth-warmest year on record in 2018, capping off a run of four years in row where global temperatures were the highest on record, according to Europe's Copernicus Climate Change Service.

The average global temperature across all of Earth's surface was 14.7 degrees Celsius in 2018, or more than 0.4 degrees Celsius above the 1981-2010 average, the agency said. That may not seem far above average, but when it comes to global temperatures, it's a significant margin.

Last year's average global temperature was 0.2 degrees Celsius below the warmest year on record set in 2016. Earth's second- and third-warmest years are 2017 and 2015, respectively.

Much of the globe had warmer-than-average temperatures in 2018, as depicted in orange on the analysis above. There were a few pockets of cooler-than-average temperatures over northeast North America, central Asia and parts of the northern Atlantic Ocean and southern Pacific Ocean.
