Last month, southern India experienced devastating landslides due to heavy rains, with nearly 200 fatalities and over 130 people still missing in Kerala state. A rapid analysis by the World Weather Attribution group revealed that these extreme weather events were exacerbated by human-caused climate change.
According to the study, the 5.91 inches of rain that fell within a 24-hour period from July 29-30 were 10% more intense because of global warming, and future emissions of greenhouse gases are expected to lead to more frequent and severe downpours.
The study highlights that the intense rainfall in Kerala was the third heaviest on record since 1901, underscoring the increasing severity of monsoon rains in India. The region’s vulnerability to extreme weather is not new; in 2018, heavy rainfall resulted in extensive flooding and the deaths of at least 500 people.
In addition, a cyclonic storm in 2017 claimed at least 250 lives, further emphasizing the area’s susceptibility to climate-driven disasters.
India’s monsoon rains have become more unpredictable and intense due to climate change, leading to increased incidents of floods and landslides. The study points out that the intensity of these events is projected to rise as global temperatures continue to climb.
As a result, the country faces significant challenges, including the need for improved early warning systems and better land use practices to mitigate the impacts of such extreme weather.
Climate scientists argue that ongoing reliance on fossil fuels will continue to exacerbate these weather extremes. The study recommends reducing deforestation, limiting quarrying, and enhancing early warning and evacuation systems to protect vulnerable populations.
Kerala, in particular, has suffered from a significant loss of forest cover, with a 62% decrease in forested areas potentially contributing to the increased risk of landslides.
The study underscores the urgent need for adaptation measures in the face of climate change. As extreme weather events become more common, establishing effective warning systems and avoiding construction in high-risk areas are critical steps. The findings serve as a stark reminder of the urgent need for global action to address climate change and its impacts on vulnerable regions like Kerala.
