PARK CITY, Utah — The National Centers for Environmental Information (NCEI) at the National Oceanic and Atmospheric Administration (NOAA) recently released data showing that July 2021 was the world’s hottest month ever recorded.

“In this case, first place is the worst place to be,” said NOAA Administrator Rick Spinrad, Ph.D. “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.”

Other data released by the NOAA:

• Around the globe: the combined land and ocean-surface temperature was 1.67 degrees F (0.93 of a degree C) above the 20th-century average of 60.4 degrees F (15.8 degrees C), making it the hottest July since records began 142 years ago. It was 0.02 of a degree F (0.01 of a degree C) higher than the previous record set in July 2016, which was then tied in 2019 and 2020.
• The Northern Hemisphere: the land-surface only temperature was the highest ever recorded for July, at an unprecedented 2.77 degrees F (1.54 degrees C) above average, surpassing the previous record set in 2012.
• Regional records: Asia had its hottest July on record, besting the previous record set in 2010; Europe had its second-hottest July on record—tying with July 2010 and trailing behind July 2018; and North America, South America, Africa and Oceania all had a top-10 warmest July.

“Scientists from across the globe delivered the most up-to-date assessment of the ways in which the climate is changing,” Spinrad said in a statement. “It is a sobering IPCC report that finds that human influence is, unequivocally, causing climate change, and it confirms the impacts are widespread and rapidly intensifying.”

According to NCEI’s Global Annual Temperature Rankings Outlook, 2021 will likely rank as one of the world’s top 10 hottest years on record.
