Asia’s Deadly Floods Are a Warning the World Is Ignoring

The recent floods in South and Southeast Asia are a further warning of how serious the climate crisis has become. Flooding and landslides have devastated large parts of Indonesia, Malaysia, Thailand and Sri Lanka. More than 1,250 people have lost their lives, many more are missing, and hundreds of thousands have been made homeless.

The human cost of this catastrophe places it among the worst climate-linked disasters in Southeast Asia in recent decades.

Cyclones, a typhoon and torrential rain

Almost the entire Southeast Asian region experienced weeks of heavy and prolonged rainfall in November. Then, in late November–early December 2025, the area was hit by a typhoon, two cyclones and several smaller tropical storms, triggering an enormous wave of flooding and landslides.

The hardest hit was the Indonesian island of Sumatra, but the disaster also devastated parts of southern Thailand, Malaysia, Sri Lanka, and neighbouring countries.

Entire villages were buried under mud; homes and infrastructure were swept away; roads and bridges were destroyed, cutting off access to many areas and making relief efforts far more difficult.

Why Deaths in Asia Rarely Make the Headlines

Disasters and deaths in Asia rarely receive the same media attention as wildfires in Los Angeles or floods in Europe. Much of the “mainstream media” is concentrated in the US and Europe, largely because that is where the wealth of its audience lies. Events affecting Africans and Asians are too often treated as distant or abstract, lacking the same “news value” as deaths in wealthy countries.

Yet climate disasters will reach virtually every corner of the globe, and with increasing frequency. What happens in Asia today is a warning of what others will face tomorrow.

Much worse is still to come

Climate models are becoming more accurate, and scientists can now make fairly confident predictions about future climate trends. While uncertainties remain, the overall direction is clear.

• Intense rainfall, flooding and landslides will increase, according to the IPCC’s Sixth Assessment Report (AR6). This will particularly happen in Southeast Asia, but also across North America, parts of South America, northern Europe, South Asia and sub-Saharan Africa. As more heat is trapped in the atmosphere, cyclones, typhoons and hurricanes will become stronger and more destructive.
• Extreme heat will become far more common. The World Meteorological Association in a climate change report shows that deadly events like recent European heatwaves will occur more frequently across southern Europe, the US, Africa and most of Asia, with very few regions spared rising temperatures.
• IPCC’s Sixth Assessment Report (AR6) predicts that droughts and wildfires will intensify in the western United States, southern Europe, Africa, Central Asia and China, as higher temperatures increase evaporation and dry out soils and vegetation.
• A Fact Sheet in the Sixth Assessment Report Rapid indicattes that glacier loss in the Hindu Kush–Himalayas will reduce flows in major river systems — including the Indus, Ganges, Brahmaputra, Yangtze and Mekong — threatening water security for over two billion people later this century.🔗
• Sea-level rise will displace millions. The IPCC is notoriously conservative in their predictions. Making allowance for their conservatism, their models suggest strongly that global sea levels will rise around one metre by mid-century. Climate Central reports that the greatest risks are in coastal megacities such as Shanghai, Mumbai, Bangkok, Jakarta and Manila, and in densely populated deltas like Bangladesh’s Ganges–Brahmaputra delta, the Mekong and the Nile. For many small island states, including the Maldives and Pacific atolls, large-scale relocation may become unavoidable.

Climate Scientists: We Have Run Out of Time

Scientists are ringing the alarm bells. On 27 November 2025, a group of climate scientists addressed a “national emergency briefing” in London. According to The Guardian, “more than 1,000 corporate leaders, senior civil servants and civic figures” were invited, along with many MPs.

What they heard should not have been new. Scientists have been issuing these warnings for many years. One of the starkest came from Kevin Anderson, Professor of Energy at Manchester University:

“It is now too late for non-radical futures. We need revolutionary changes in how we live. The choice is between deep, rapid decarbonization through organized technical and social revolution, or facing chaotic and violent change as temperatures reach dangerous levels for everyone.”

Events such as the Asian floods should be a wake-up call for governments around the world. Instead, politicians at COP30, locked into their capitalist straightjackets, were unable even to acknowledge the need to move away from fossil fuels.
