Argentina's late-season heatwave has "no analogues in history" and is "endless, merciless heat."

Argentina is facing an unprecedented late-summer heatwave, causing crops to wither, helping wildfires spread and adding to the country's economic crisis. Maximiliano Herrara, a climatologist who tracks extreme temperatures across the globe, said the temperature anomalies, which have persisted over huge areas, are unprecedented. He had expected a "scorching summer" due to La Niña, a climate pattern which tends to bring hotter, drier summers to the region, but what has happened shocked him.
