Climate change turned up India’s heat.But by how much?
Live MintIndia this year experienced its hottest March in 12 decades of records, and one of its driest. “The number of heat waves is directly in response to global warming,” says Roxy Mathew Koll, a climate scientist at the Indian Institute of Tropical Meteorology who has looked at 70 years of data. Analyzing decades of heat data is different from asking about one hot spell in particular — and looking for answers about India’s heat is harder than most anywhere else in the world. When researchers at World Weather Attribution, a project that untangles the climate influence on extreme weather, examined a deadly 2016 heat wave in northwestern India, they found that peak daily temperatures didn’t carry a strong climate signal. World Weather Attribution’s research concluded the Siberian heat was made more than 600 times likelier by greenhouse gas pollution.
