Climate change: July world’s hottest month ever – US agency
July was the world’s hottest month ever recorded, a US federal scientific and regulatory agency has reported.
The data shows that the combined land and ocean-surface temperature was 0.93C (1.68F) above the 20th Century average of 15.8C (60.4F).
It is the highest temperature since record-keeping began 142 years ago. The previous record, set in July 2016, was equalled in 2019 and 2020.
Experts believe this is due to the long-term impact of climate change.
In a statement, the National Oceanic and Atmospheric Administration (NOAA) said that July’s “unenviable distinction” was a cause for concern.
“In this case, first place is the worst place to be,” NOAA administrator Rick Spinrad said in a statement.
“This new record adds to the disturbing and disruptive path that climate change has set for the globe.”
The combined land and ocean-surface temperature was 0.01C higher than the 2016 record.
In the Northern Hemisphere, land-surface temperature reached an “unprecedented” 1.54C higher than average, surpassing a previous record set in 2012.
The NOAA statement also included a map of significant climate “anomalies” in July, which noted that global tropical cyclone activity this year has been unusually high for the number of named storms.
Earlier this week, a report from the United Nations said that climate change is having an “unprecedented” impact on earth, with some changes likely to be “irreversible for centuries to millennia.”
UN Secretary General António Guterres said that the findings were “a code red for humanity.”
“If we combine forces now, we can avert climate catastrophe. But as today’s report makes clear, there is no time for delay and no room for excuses,” he said.
The authors of the report say that since 1970, global surface temperatures have risen faster than in any other 50-year period over the past 2,000 years.
