Asia is bearing the heaviest burden of the global climate crisis, with a cascade of extreme weather events in the first half of 2026 reshaping the lives of hundreds of millions of people across the continent and forcing governments to confront the accelerating human and economic costs of inaction. From record-shattering heat waves in South and Southeast Asia to catastrophic flooding in Bangladesh and the Philippines, the region that contributes enormously to global carbon emissions is also the one suffering most visibly from their consequences.

In May, a heat dome settled over northern India and Pakistan for nearly three weeks, pushing temperatures to levels that meteorologists described as unprecedented in recorded history. Jacobabad in Pakistan — already notorious as one of the few places on Earth where “wet bulb” temperatures regularly approach the limits of human survivability — recorded a peak of 54.2 degrees Celsius. In Delhi, the temperature touched 49.8 degrees for four consecutive days. Hospitals across Rajasthan, Uttar Pradesh, and Sindh were overwhelmed with heat stroke patients. The Indian government confirmed at least 1,400 heat-related deaths during the event, though health researchers say the true toll is likely two to three times higher once excess mortality from cardiovascular and respiratory failures is factored in.

The impacts on agriculture were severe. Wheat crops across Punjab and Haryana — India’s breadbasket — suffered significant damage as the heat arrived during the critical grain-filling stage. Preliminary estimates from the Indian Council of Agricultural Research suggest a production shortfall of between 8 and 12 percent compared to last year’s harvest. For a country that exports wheat to food-insecure nations across the Middle East and Africa, the knock-on effects extend far beyond its borders.

Bangladesh faced a different but equally devastating extreme. Three consecutive pre-monsoon storm systems brought record rainfall to the Sylhet and Mymensingh divisions in late April and May, triggering floods that inundated more than two million homes and displaced an estimated 7.5 million people. The floods, which experts say were intensified by warmer Bay of Bengal sea surface temperatures, arrived earlier in the year than typical monsoon flooding — catching communities and emergency systems off guard. Infrastructure damage, including roads, bridges, and schools, is estimated at over $2 billion. Recovery in a country that already channels a substantial share of its GDP into climate adaptation will stretch resources to their limits.

In the Philippines, Typhoon Karingal struck the Visayas region in late May with sustained winds of 230 kilometers per hour — making it the most powerful typhoon to make landfall in the Philippines before June since records began. The storm killed 312 people, destroyed approximately 80,000 homes, and devastated fishing communities across Samar and Leyte. Scientists with the World Weather Attribution group published a rapid analysis within days of the storm’s landfall, concluding that human-caused climate change made Karingal approximately 30 percent breaks 30 percent more intense than it would have been in a pre-industrial climate.

The policy response across the region is uneven. China, the world’s largest emitter of greenhouse gases, is on track to meet its targets for peak emissions before 2030, driven by an extraordinary buildout of solar and wind capacity. The country installed more renewable energy in 2025 than the rest of the world combined, and its share of coal in the electricity mix fell below 50 percent for the first time in modern history. Yet absolute emissions remain enormous, and the pace of coal phase-out in rural and industrial provinces lags behind the national headline figures.

India, now the world’s third-largest emitter, has made significant strides in solar deployment but faces pressure to define a firmer coal exit date. The government’s position, articulated at the last two COP summits, is that coal phase-down must go hand-in-hand with guaranteed finance from developed nations to support the transition — a stance supported by most developing country blocs but resisted by European negotiators who want binding timelines regardless of finance conditions.

Smaller and lower-income nations across Asia are increasingly vocal about the injustice at the heart of the climate crisis: those who did least to cause it are experiencing the worst effects first. At this month’s Asian Development Bank annual meeting in Tbilisi, representatives from Bangladesh, the Maldives, and Vietnam called for a tripling of climate adaptation finance — money to build sea walls, drought-resistant crops, early warning systems, and climate-resilient infrastructure. The current pledges, they argued, are a fraction of what is needed.

The climate crisis in Asia is no longer a future scenario. It is the present reality for billions of people — and the gap between what is happening and what is being done about it has never felt wider.
