Key Messages
Climate Context
In 2023, the mean temperature over Asia was notably higher than the 1991–2020 reference period, marking the second highest temperature on record. Many regions experienced extreme heat events, including Japan’s hottest summer on record. Glaciers in High-Mountain Asia have shown significant mass loss over the past four decades, with the rate accelerating.
Ocean and Cryosphere Trends
The ocean around Asia exhibited an overall warming trend since the beginning of time series in 1982. In 2023, sea-surface temperature anomalies in the north-west Pacific Ocean reached record highs. South-west China faced severe drought conditions due to below-normal precipitation throughout most of 2023.
Extreme Events
Over 80% of hydrometeorological hazards reported in Asia in 2023 were flood and storm events. Yemen experienced heavy rainfall leading to widespread floods, affecting over 165,000 individuals across 70 districts.
Climate Impacts and Risks
Many countries in Asia recorded their hottest year on record in 2023, coupled with extreme conditions like droughts, heatwaves, floods, and storms. These events had significant impacts on societies, economies, and human lives.
Climate Services and Projections
Approximately 80% of World Meteorological Organization (WMO) Member countries in the region provide climate services supporting disaster risk reduction activities. However, there is a notable gap in climate projections and tailored products needed for effective risk management and adaptation to mitigate climate change impacts.
WMO Commitment
WMO is dedicated to providing science and services aimed at reducing disparities and addressing developmental gaps in climate change mitigation and adaptation. The organization prioritizes regional initiatives and ensures innovative solutions reach every Member, especially those facing greater developmental challenges. The present report serves as a tool for regional decision-making, highlighting the importance of informed strategies in response to climate change.
Call to Action
WMO remains committed to monitoring the climate system and delivering authoritative information to leaders and the public. The organization leverages robust collaboration across the United Nations family and partnerships to provide impactful services grounded in reliable information. WMO's pledge includes reaching every corner of the globe, ensuring no Member or individual is left behind in the fight against climate change.
Collaboration and Contributions
The creation of such reports relies heavily on collaboration among WMO Members, sister United Nations agencies, and experts from around the world who contribute to scientific coordination and authorship. The Secretary-General expresses gratitude to all contributors for their invaluable work in advancing climate science and services in Asia and beyond.
