Asia is experiencing a rapid acceleration in climate change, warming at twice the rate of the global average, according to a new report by the World Meteorological Organization (WMO). This alarming trend, highlighted in the WMO’s latest assessment released in June 2025, points to sweeping and devastating impacts for millions across the continent—including Thailand—underscoring urgent calls for adaptation and resilience measures.
For Thai readers, this news is particularly significant given the country’s vulnerability to heat waves, shifting rainfall patterns, and sea-level rise. Thailand, with its extensive agricultural sector and dense urban populations near coasts and rivers, stands at the frontline of Asia’s climate crisis.
The WMO report reveals that the continent’s warming is driven largely by its vast landmass, which causes surface temperatures to rise more quickly compared to oceans. Land absorbs and retains heat at a higher rate, intensifying fluctuations and amplifying extreme weather events. According to the WMO, “Variations in surface temperature have a large impact on natural systems and on human beings,” a statement that resonates deeply across nations reliant on agriculture, fisheries, and tourism—sectors vital to the Thai economy (news.un.org).
In 2024, Asia set numerous records for both high temperatures and oceanic heat. The Indian and Pacific Oceans registered surface temperature highs, further affecting weather systems, marine life, and coastal livelihoods. Prolonged land and sea heatwaves led to accelerated melting of glaciers, particularly in the Himalayas, and contributed to rising sea levels threatening low-lying areas across Southeast Asia, including southern Thailand’s shores.
The WMO underscores that these changes are manifesting in increasingly erratic and destructive weather patterns—sometimes causing too much water in the form of floods, and sometimes too little as droughts. For instance, northern Kerala, India, witnessed a catastrophic landslide after record rainfall, resulting in over 350 deaths. Meanwhile, the combination of snowmelt and heavy rain in Kazakhstan led to the worst flooding in 70 years. China experienced a multi-month drought affecting nearly 5 million people and hundreds of thousands of hectares of crops, a stark warning for agriculture-reliant partners across the region.
WMO Secretary-General Celeste Saulo put it bluntly, “Extreme weather is already exacting an unacceptably high toll.” This comment mirrors concerns expressed regularly by Thailand’s own Department of Disaster Prevention and Mitigation, which updates the public on heatwave advisories and flash flood warnings, especially as El Niño and La Niña phenomena magnify local extremes (news.un.org).
One positive case study cited in the WMO report is Nepal, where robust early warning systems have made a life-saving difference. In September 2024, Nepal endured record rainfall, landslides, and flooding that left hundreds dead and missing. However, the presence of local flood warning systems and swift emergency funding protocols ensured timely evacuations, significantly reducing the casualty rate in hard-hit areas. The WMO now encourages Asia-Pacific nations—including Thailand—to enhance such local preparedness efforts.
“This is the first time in 65 years that the flooding was this bad. We had zero casualties thanks to preparedness and rescue measures, but the damage was extensive,” said the mayor of an eastern Nepalese municipality, as quoted in the report. The swift mobilization of humanitarian aid was attributed to clear national protocols—a model Thailand could strengthen further at both national and community levels.
For Thailand, the lessons from Nepal and neighboring countries are clear. The expansion of comprehensive early warning systems, especially in flood-prone provinces like Nakhon Si Thammarat, Phitsanulok, or along the Chao Phraya River, is crucial. The Thai Meteorological Department has made strides in this area, linking real-time data with public warning systems, yet challenges remain with last-mile dissemination in rural or highland communities (news.un.org).
Historically, Thailand’s monsoon and dry seasons have shaped the nation’s culture, economy, and food security. Traditionally, Thai farmers observe the changing colors of the sky, wildlife behavior, and even Buddhist festival calendars to anticipate seasonal shifts. However, climate change is disrupting these patterns, leading to increased reliance on satellite-based data, rainfall radars, and regional meteorological cooperation with ASEAN neighbors.
Looking forward, climate experts warn that without bold adaptation measures, economic losses from heat stress, crop failure, and infrastructure damage will escalate. Recent studies from Chulalongkorn University have modeled scenarios showing that reductions in rice and aquaculture yields could threaten food security, while cities like Bangkok may face more frequent urban flooding unless drainage and seawall projects are accelerated (bangkokpost.com). If greenhouse gas emissions continue unchecked, temperatures in Thailand may rise by an additional 2–3°C by the end of the century, exacerbating health risks, water scarcity, and economic instability.
To mitigate these threats, the WMO and international partners advocate for investment in resilience: bolstering early warnings, training local officials, introducing climate-resilient crops, and updating urban planning for flood defense. Thai policymakers are advised to strengthen cooperation with the ASEAN Climate Resilience Network and prioritize public awareness campaigns, ensuring citizens—from students to farmers to business owners—understand local risks and response plans.
For Thai readers, the call to action is both collective and immediate. Individuals can engage in “climate-smart” behaviors such as monitoring weather advisories, participating in community drills, conserving water, and reducing household energy consumption. Local groups and schools can organize tree-planting days, which support both microclimate stability and biodiversity. Urban communities can advocate for green infrastructure, such as flood-proof parks, permeable pavements, and expanded canal networks to absorb and redirect excess water.
Finally, citizens are encouraged to follow updates from the Thai Meteorological Department and local authorities, participate in public consultations on climate policy, and support science-based decision-making. As the WMO report makes clear, the pace of warming is unlikely to slow soon, but proactive adaptation—anchored in science and community solidarity—can help Thailand weather the climate storm.
