July was the hottest month on record in 143 years, as Americans felt “the effects of the climate crisis,” scientists at NASA’s Goddard Institute for Space Studies in New York announced Monday.
According to NASA, July 2023 was on average 0.43 degrees Fahrenheit warmer than any other July on record. It was also 2.1 degrees warmer than the average July between 1951 and 1980, according to GISS which defines “normal” temperatures as lasting several decades, typically 30 years. The five hottest Julys since 1880 have all occurred in the past five years, NASA says.
“This July was not just warmer than any previous July — it was the warmest month in our record, which goes back to 1880,” NASA’s GISS Director Gavin Schmidt said.
“The science is clear this isn’t normal. Alarming warming around the world is driven primarily by human-caused greenhouse gas emissions. And that rise in average temperature is fueling dangerous extreme heat that people are experiencing here at home and worldwide,” Schmidt added.
