NASA confirms: 2022 was the fifth hottest year ever recorded
Another group, whose satellite-based calculations tend to run cooler than other science teams, said it was the seventh hottest year.
In a human body an extra 2 degrees Fahrenheit is considered a fever, but University of Oklahoma meteorology professor Renee McPherson, who wasn’t part of any of the study teams, said the global warmth is actually worse than the equivalent of a planetary fever because fevers can be treated to go down quickly.
The likelihood of the world shooting past the 1.5 degrees Celsius warming threshold that the world adopted in 2015 is increasing with every year, said the World Meteorological Organization. The United Nations weather agency said the last 10 years average 1.14 degrees Celsius warmer than pre-industrial times.
The La Nina, a natural process that alters weather worldwide, is in its third straight year. Schmidt calculated that last year the La Nina cooled the overall temperature by about a tenth of a degree and that last year was the hottest La Nina year on record. “That would suggest that 2024 would be the record warmest year by quite a large amount,” Schmidt said in an interview with The Associated Press.
In the United States, global warming first grabbed headlines when Schmidt’s predecessor, climate scientist James Hansen, testified about worsening warming in 1988. That year would go on to be the record warmest at the time.The last year that the Earth was cooler than the 20th century average was 1976, according to NOAA.
