El Niño's Prolonged Impact: Heatwaves and Extreme Weather Expected

El Niño is expected to continue through March 2024, exacerbating hot temperatures driven by human-caused climate change and increasing the likelihood of heat records being broken worldwide. The first half of 2023 was extremely warm, with June being the hottest ever recorded. The southern U.S. has experienced record-breaking heat, with nearly 400 daily maximum temperature records falling in June and July. The heat is predicted to persist, with hotter-than-average temperatures expected for the next three months. 2023 has a more than 90% chance of ranking among the 5 hottest years on record.
