2024 Confirmed as Hottest Year on Record, Surpassing 1.5°C Threshold

The WMO's climate report highlights accelerating impacts, record greenhouse gas levels, and the urgent need for stronger global action.

Global temperatures in 2024 averaged 1.55°C above pre-industrial levels, breaking previous records and exceeding the 1.5°C threshold for the first time in a single year.
Greenhouse gas concentrations, including carbon dioxide, reached their highest levels in 800,000 years, driving ocean warming, glacier loss, and rising sea levels.
Sea levels rose at a record rate, with the long-term increase doubling since satellite measurements began, while glaciers experienced unprecedented mass loss over the past three years.
Extreme weather events displaced more than 800,000 people in 2024, the highest annual figure since records began in 2008, and worsened food crises in 18 countries.
Despite progress in renewable energy adoption, the WMO report warns that current global efforts remain insufficient to mitigate escalating climate risks.
