The Earth Just Experienced the Hottest Month on the Books. Period.

On Monday it was confirmed that the Earth has broken an ominous climate milestone amid a wave of troubling records: July 2016 was the hottest recorded month—ever.

According to new NASA data, the global mean surface temperatures last month were 0.84° Celsius (1.51° Fahrenheit) above average and was the warmest July in their data set, which dates back to 1880.

This marks the 10th straight month to set a new monthly warming record, based on NASA’s analysis. “Every month so far this year has been record hot,” reported Climate Central‘s Andrea Thompson. “In NASA’s data, that streak goes back to October 2015, which was the first month in its data set that was more than 1C hotter than average.”

The National Oceanic and Atmospheric Administration (NOAA) releases its monthly temperature report on Wednesday and it is likely theirs will reflect a 15-month streak of record-shattering heat. (Some previous reporting on monthly records here, here, here, and here.)

What’s more, because July is typically the hottest month of the year, it stands that July 2016 was “the warmest month of any in a data record that can be extended back to the nineteenth century,” according to the U.K.-based Copernicus Climate Change Service (CCCS), which last week published similar temperature results.
