The catastrophic floods in Nepal are the latest chapter in a broader pattern of extreme weather disasters that have repeatedly struck South and Southeast Asia over the past year. In late 2025, catastrophic floods and landslides across Indonesia, Sri Lanka, and Thailand killed more than 1,500 people, with Indonesia alone confirming 867 fatalities and Sri Lanka 486. Those disasters were driven by rare cyclonic storms near the equator that brought the heaviest rainfall seen in decades and displaced over four million people.

The pattern continued into 2026, with severe monsoon seasons claiming lives across the region. India's monsoon season since July has killed over 100 people, with Assam reporting at least 87 fatalities and Kerala at least 15. Pakistan's monsoon rains killed at least 107 people by late July, while Sri Lanka suffered devastating floods and landslides that killed dozens and displaced over 40,000 residents.

Scientists and officials have repeatedly linked these events to climate change, noting that glaciers in the Himalayas are melting at an accelerated rate due to rising global temperatures. Researchers have also pointed to deforestation and environmental degradation as factors that strip away natural defenses against flooding, making communities more vulnerable to catastrophic weather events.
