A new study links rising temperatures and subsequent crop failures to more than 59,000 suicides in India over the past 30 years. The study, published in the Proceedings of the National Academy of Sciences, analyzed 47 years of suicide records from India’s National Crime Records Bureau, as well as data on temperature, climate, and crop yields. It found that on days above 68 degrees Fahrenheit, a 1.8 degrees rise in temperature caused an average of 70 suicides. This correlation was found only during growing seasons, when higher temperatures can damage crop yields and deal devastating blows to the one-third of Indian farmers who live below the international poverty line.
