Record-breaking temperatures were recorded this September, driving heatwaves and wildfires across the world.
Global temperatures also soared in July and August, setting the record for the warmest months ever. September 2023 beat the previous record by 0.5C.
While human activities can not be discounted, the uptick is linked to the El Nino phenomenon. This releases ocean heat and increases temperature.
Multiple European countries, including Germany, France and Poland, have reported record heat levels. UK also experienced its hottest summer on record.
Scientists said similar temperatures are expected next year, if not more. The heating impact of El Nino lingers for a full year.
