摘要

July 2021 was the hottest month ever recorded on earth, according to NOAA's National Centers for Environmental Information. 'In this case, first place is the worst place to be," said NOAA Administrator Rick Spinrad. "July is typically the world's warmest month of the year, but July 2021 outdid itself as the hottest July and month ever recorded. This new record adds to the disturbing and disruptive path that climate change has set for the globe." According to the data released by NOAA, the combined land and ocean surface temperature was 1.67°F (0.93 of a degree Celsius) above the 20th-century average of 60.4°F (15.8℃), making it the hottest July since records began 142 years ago. It was 0.02 of a degree Fahrenheit (0.01 of a degree Celsius) higher than the previous record set in July 2016, which was then tied in 2019 and 2020. In the Northern Hemisphere, the land-surface-only temperature was the highest ever recorded for July, at 2.77°F (1.54℃) above average, surpassing the previous record set in 2012. In specific locations, Asia recorded its hottest July, Europe had its second-hottest July on record, and North America, South America, Africa, and Oceania all had a top 10 warmest July.
