State of the Climate in Asia 2023

23 April 2024

Asia remained the world’s most disaster-hit region from weather, climate and water-related hazards in 2023. Floods and storms caused the highest number of reported casualties and economic losses, whilst the impact of heatwaves became more severe.

The State of the Climate in Asia 2023 report highlighted the accelerating rate of key climate change indicators such as surface temperature, glacier retreat and sea level rise, which will have major repercussions for societies, economies and ecosystems in the region.

The report, one of a series of WMO regional State of the Climate reports, was released during the 80th session of the Commission in Bangkok, Thailand. It is based on input from National Meteorological and Hydrological Services, United Nations partners and a network of climate experts. It reflects WMO’s commitment to prioritize regional initiatives and inform decision-making.
