Overview

  • Global average temperatures in 2024 reached 1.55°C above pre-industrial levels, exceeding the 1.5°C threshold for the first time in a calendar year.
  • Ocean heat content hit a record high for the eighth consecutive year, contributing to accelerated sea level rise and widespread coral bleaching.
  • The largest three-year glacier mass loss on record occurred from 2022 to 2024, with Antarctic sea ice shrinking to its second-lowest extent ever recorded.
  • Extreme weather events in 2024 displaced the highest number of people since 2008, exacerbating food insecurity and economic instability worldwide.
  • Atmospheric carbon dioxide levels are now at their highest in at least 800,000 years, driving long-term warming and irreversible changes to ecosystems.
