State of the Global Climate 2024

The clear signs of human-induced climate change reached new heights in 2024, with some of the consequences being irreversible over hundreds if not thousands of years, according to this year's State of the Global Climate report, which underlined the massive economic and social upheavals from extreme weather.

WMO’s flagship report confirmed that 2024 was likely the first calendar year to be more than 1.5°C above the pre-industrial era, with a global mean near-surface temperature of 1.55 ± 0.13 °C above the 1850-1900 average. This is the warmest year in the 175-year observational record.

Two featured articles highlight the monitoring of progress towards the Paris Agreement targets and examine the contributing factors to the record-breaking heat in 2024.

Supplementary reports detail the state of climate services and extreme events throughout the year, including floods, droughts, tropical cyclones and wildfires, and highlight the urgent need for stronger early warning systems and greater investment in climate services to protect communities and ecosystems from growing risks.
