Key factors
The global average temperature reached 17.18 degrees Celsius (62.92 degrees Fahrenheit) on Tuesday, according to data from the University of Maine’s Climate Change Institute shownthe hottest ever recorded on any day of any year.
The same record was broken the day before, when temperatures on July 3 reached 17.01 degrees Celsius (62.62 degrees Fahrenheit), higher than the previous record for the hottest day of 16.92 degrees Celsius held by a tie of two dates, July 24, 2022 and August. 14, 2016, according to the University of Maine and the National Centers for Environmental Prediction.
The exact modeling system used to estimate Tuesday’s temperature has only been in use since 1979, but scientists are able to estimate average temperatures going back tens of thousands of years using instrument-based global temperature records. tree rings and ice cores, according to climate scientist Paulo Ceppi. he told the Washington Post.
Washington Post Heat Index forecast said up to 57 million people in the United States were exposed to dangerous heat on Tuesday.
Extreme heat advisories and advisories remain in effect Wednesday for all of Florida, parts of the Pacific Northwest, southern Texas and other areas, the National Weather Service reports, although a weeks-long heat wave in Texas and other southern states eventually declined.

Global temperatures have increased during years due to human-caused climate change, but Tuesday’s scorching temperatures were also driven by the first El Niño weather pattern since 2018-19. The World Meteorological Organization of the United Nations notified on Tuesday that billions of people will be affected as El Niño brings warmer sea surface temperatures and unleashes extreme heat on both the ocean and land. An El Niño pattern weakens trade winds and pushes warm water toward America’s West Coast, National Ocean Service he says, making areas of the northern US and Canada drier and warmer than usual. The US Gulf Coast and Southeast often see wetter than usual weather and increased flooding. El Niño is expected to increase global temperatures over the next 9 to 12 months, the WMO predicted.
What to watch out for
More records broken. The return of the El Niño weather pattern for the first time in four years means more extreme weather and an acceleration in global warming, which would mean more record heat next year. A WMO report published in may predicts that there is a 98% chance that at least one of the next five years—and the five-year period as a whole—will be the warmest on record.
Crucial appointment
“Early warnings and early action. . . they are vital to saving lives and livelihoods,” said Petteri Taalas, WMO Secretary-General Professor said.
