The study also predicts that the Gulf could become the world's hottest region by 2100, due to climate change. If no action is take to prevent climate change , South Asia could become uninhabitable , according to a study by scientists at the Massachusetts Institute of Technology ( MIT ) . The scientists measured " wet - bulb temperature " , a combination of the sun 's ability to cool down , humidity and heat content . Currently 20 % of India 's population is exposed to potentially lethal wet - bulb temperatures , but this could rise to as much as 70 % within the century , according to the MIT study .
