BLOOMINGTON, USA, Jun 23 2025 – Asia is heading towards more extreme weather events with a possibility of heavy toll on the region’s economies, ecosystems, and societies, says the World Meteorological Organization (WMO).
The WMO’s State of the Climate in Asia 2024 report released today says Asia is currently warming nearly twice as fast as the global average, fueling more disaster-prone weather events.
In 2024, Asia’s average temperature was about 1.04°C above the 1991–2020 average, ranking as the warmest or second warmest year on record, depending on the dataset. The warming trend between 1991 and 2024 was almost double that during the 1961 to 1990 period.
Report highlights the changes in key climate indicators, including surface temperature, glacier mass, and sea level, which will have major impacts in the region. “Extreme weather is already exacting an unacceptably high toll,” said WMO Secretary-General Celeste Saulo.
In 2024, heatwaves gripped a record area of the ocean. Sea surface temperatures were the highest on record, with Asia’s sea surface 10 years period warming rate nearly double the global average.
Report says that sea level rise on the Pacific and Indian Ocean sides of the continent exceeded the global average, increasing risks for low-lying coastal areas.
“The work of National Meteorological and Hydrological Services and their partners is more important than ever to save lives and livelihoods,” Saulo said.

Water Resources Are in Danger and Causing Destruction
State of the glaciers, which are regarded as water storage for most of the region, is facing an existential threat. Reduced winter snowfall and extreme summer heat caused decisive damage to glaciers in the central Himalayas and Tian Shan Mountain range. 23 out of 24 glaciers suffered mass loss, leading to an increase in hazards like glacial lake outburst floods and landslides and long-term risks for water security.
The High-Mountain Asia (HMA) region, centered on the Tibetan Plateau, contains the largest volume of ice outside the polar regions, with glaciers covering an area of approximately 100,000 square km. It is known as the world’s Third Pole. Over the last several decades, most glaciers in this region have been retreating. Which is increasing the risk of glacier lake outburst floods (GLOFs).
Community in Thame village in the Mt. Everest region in Nepal is still recovering from the disaster caused by a small glacial lake outburst flood in August 2024, while living in fear of a similar disaster.
From the high Himalayas to coastal areas in Asia experiencing destructive weather events. Extreme rainfall caused great damage and heavy casualties in many countries in the region, tropical cyclones left a trail of destruction, and drought added heavy economic and agricultural losses.
The report included a case study from Nepal, showing how important early warning systems and anticipatory actions are to prepare for and respond to climate variability and change. In late September 2024, Nepal experienced heavy rainfall that led to severe flooding and landslides across the country.
According to the government data, the disaster claimed at least 246 lives and left 218 people missing. Damages to energy infrastructure are estimated at 4.35 billion Nepali rupees, while the agricultural sector faced a loss equivalent to 6 billion Nepali rupees. Reports note that early warning systems and preparation for anticipatory actions helped limit human casualties. But the Department of Hydrology and Meteorology (DHM) in Nepal highlighted the urgent need for a tailored, impact-based flood forecasting system at the national level.
Extreme heat events
In many parts of Asia, extreme heat is becoming a concerning issue as countries like India, Bangladesh, and Pakistan in South Asia are already dealing with heat waves. In 2024, prolonged heat waves affected East Asia from April to November.
According to the report, Asia is the continent with the largest landmass extending to the Arctic and is warming more than twice as fast as the global average because the temperature increase over land is larger than the temperature increase over the ocean.
In 2024, most of the ocean area of Asia was affected by marine heatwaves of strong, severe, or extreme intensity—the largest extent since records began in 1993. During August and September 2024, nearly 15 million square kilometers of the region’s ocean were impacted—one-tenth of the Earth’s entire ocean surface.
“The purpose of the report is not only to inform. It is to inspire action,” said president of WMO Regional Association Dr. Ayman Ghulam.
He highlighted the need for stronger early warning systems, regional collaboration, and greater investments in adapting transboundary water and climate risk management.
“We must ensure that modern science guides decision-making at every level,” Ghulam said.
