Human-induced climate change intensified rainfall by roughly 10%, triggering devastating landslides in Kerala, India, last month. Over 200 people perished in the disaster. A new study by the World Weather Attribution group confirms this link.
Wayanad, a coastal region, bore the brunt of the July 30 landslides. This was Kerala’s most severe calamity since the 2018 floods, which claimed over 400 lives. The study reveals that single-day monsoon downpours in the area have intensified by 10% due to climate change.
The region experienced a staggering 572 millimeters of rain in 48 hours, double the forecast. Climate change will exacerbate the situation, with another 4% increase in one-day rainfall expected if global warming reaches 2 degrees Celsius.
The study warns of heightened landslide risks due to intensified rainfall. To prevent future disasters, the report recommends measures like reducing deforestation, reinforcing slopes, and constructing protective structures.
Experts also highlight other factors contributing to the landslides, including excessive rainfall, unchecked development, and tourism. Adaptation along with improved landslide assessments, early warning systems, and evacuation plans are essential.
Kerala’s ordeal is part of a broader pattern of climate-related disasters in India. Soaring temperatures, heatwaves, and cyclones have become increasingly common. The evidence is clear: climate change is a major threat multiplier. Urgent action is needed to mitigate its impacts and protect vulnerable communities.
