June 13, 2023 — El Niño is officially here, and that means things are about to get even hotter. The natural climate phenomenon is marked by warmer ocean temperatures in the equatorial Pacific, which drives hotter weather around the world.
“[El Niño] could lead to new records for temperatures,” says Michelle L’Heureux, a climate scientist at the National Oceanic and Atmospheric Administration’s Climate Prediction Center.
The hottest years on record tend to happen during El Niño. It’s one of the most obvious ways that El Niño, which is a natural climate pattern, exacerbates the effects of climate change, which is caused by humans burning fossil fuels and releasing greenhouse gasses into the atmosphere.
