Earth just roasted under its hottest July on record, according to scientists from NOAA’s National Centers for Environmental Information (NCEI) and also ffrom scientist from NASA.

For the fourth-consecutive month, the global ocean surface temperature also hit a record high.

Overall, July 2023 was 0.24ºC warmer than any other July in NASA’s record (since 1880), and it was 1.18ºC warmer than the average July between 1951 and 1980.

Parts of South America, North Africa, North America, and the Antarctic Peninsula were especially hot, experiencing temperatures increases around 4ºC above average. Overall, extreme heat this summer put tens of millions of people under heat warnings and was linked to hundreds of heat-related illnesses and deaths. The record-breaking July continues a long-term trend of human-driven warming driven primarily by greenhouse gas emissions that has become evident over the past four decades. According to NASA data, the five hottest Julys since 1880 have all happened in the past five years.

“Climate change is impacting people and ecosystems around the world, and we expect many of these impacts to escalate with continued warming” said Katherine Calvin, chief scientist and senior climate advisor at NASA Headquarters in Washington. “Our agency observes climate change, its impacts, and its drivers, like greenhouse gases, and we are committed providing this information to help people plan for the future.”.
