Thanks to a combination of global warming and an El Niño, the planet shattered monthly heat records for an unprecedented 12th straight month, as April smashed the old record by half a degree, according to federal scientists.
The National Oceanic and Atmospheric Administration’s monthly climate calculation said Earth’s average temperature in April was 58.7 degrees.
The Southern Hemisphere led the way, with Africa, South America and Asia all having their warmest Aprils on record, NOAA climate scientist Ahira Sanchez-Lugo said.
“These kinds of records may not be that interesting, but so many in a row that break the previous records by so much indicates that we’re entering uncharted climatic territory (for modern human society),” said Texas A&M University climate scientist Andrew Dessler.
Sanchez-Lugo and other scientists say ever-increasing man-made global warming is pushing temperatures higher, and the weather oscillation El Niño — a warming of parts of the Pacific Ocean that changes weather worldwide — makes it even hotter.
