That's insane. I do pretty well with higher temperatures as long as I have water and a chance to cool down. 95 F (35 C) with high humidity? Sounds like a good day to go biking. But that's going from an air conditioned home or office to working hard for an hour or two and then back inside a temperature controlled building.
I can't imagine having to live in temperatures like this with no relief.
Beyond the immediate human toll, we'll have to see if this becomes a trend both in Indian and globally. Climate change tells us we'll see more severe weather more often. Will peaks over 50 C become the new norm? How will people cope?
