  • This temperature increase brings the world very close to the 1.5 degrees Celsius lower limit of the Paris Agreement on climate change.
  • Around one-third of the global ocean experienced marine heatwaves in 2023, affecting ecosystems and food systems.
  • Record ice loss was observed in global reference glaciers, particularly in western North America and Europe, while Antarctic Sea ice extent hit a record low.
  • The warm temperature records were influenced by an ongoing El Nino event, associated with below-normal monsoon rainfall in India and record-breaking heat in southern India.
