India will face dangerously hot weather almost daily by century’s end – with disastrous consequences #IndiaNEWS
As global temperatures rise, people in the tropics, including places like India and Africa’s Sahel region, will likely face dangerously hot conditions almost daily by the end of the century – even as the world reduces its greenhouse gas emissions, a new study shows.The mid-latitudes, including the US, will also face increasing risks. There, the number of dangerously hot days, marked by temperatures and humidity high enough to cause heat exhaustion, is projected to double by the 2050s and continue to rise.In the study, scientists looked at population growth, economic development patterns, energy choices and climate models to project how heat index levels – the combination of heat and humidity – will change over time. We asked University of Washington atmospheric scientist David Battisti, a co-author of the study, published on August 25, to explain the findings and what they mean for humans around the world.What does the new study tell us about heat waves in the future, and importantly the impact on people?There are two sources of uncertainty when it comes to future temperature. One is how much carbon dioxide humans are going to emit – that depends on things like population, energy choices and how much the economy grows. The other is how much warming...Read more
