Climate Change Worsens Asia's Floods to Deadly Proportions
Towering cyclones and storms swept through Asia last week, unleashing torrential rains that left at least 1,200 people dead and a million more without homes. The devastating weather events have exposed the increasingly lethal consequences of global heating on the region.
Scientists say the background climate has shifted, making cyclones "wetter and more destructive". Roxy Koll, a climate scientist from India, explains that warmer air holds more moisture – about 7% per degree Celsius – leading to extreme rainfall and devastating floods. This is exacerbated by natural weather patterns like La Niña cycles and negative Indian Ocean dipoles.
The consequences are dire: homes buried under fast-flowing mud, jagged brown craters scarring lush green hillsides, and families stranded on rooftops as they desperately seek higher ground. Landslides and flash floods have struck vulnerable communities living in fragile environments, further complicating rescue efforts.
Indonesia's recent disaster is thought to have been worsened by deforestation and the felling of trees that could have soaked up water and stabilized the soil. An investigation into potential human activities contributing to the disaster has been launched, with authorities questioning logging, mining, and palm plantation companies.
Climate scientists Sonia Seneviratne and Roxy Koll agree that climate change is playing a significant role in worsening rainfall patterns across Asia. While other human factors may have amplified the extent of the floods, their research confirms that warming temperatures are increasing heavy precipitation events worldwide.
The long-term picture is one of hope – the reduction in flood-related deaths and displacement globally has been impressive, with early warning systems and better preparedness saving countless lives. However, more needs to be done to address Asia's specific vulnerabilities.
Experts point out that even with improved warning systems and shelters, the region still requires better nature-based solutions, such as reforestation and mangrove planting, to keep people safer from flooding. Social protection systems must also be strengthened to provide essential aid – food, medicine, and shelter – to those affected by disasters.
