53°C

That's 126.1°F. From Agence France-Presse (AFP) 

Temperatures in India's capital soared to a national record-high of 52.3 degrees Celsius (126.1 Fahrenheit) on Wednesday, the government's weather bureau said.

Neighbouring Pakistan has also sweltered through a week-long heatwave, which peaked at 53C (127.4F) on Sunday in Mohenjo Daro in rural Sindh province.

An online calculator for wet bulb temperatures only allows values up to 50°C. Needless to say that's above the critical value of 35°C where humans can't cool off by sweating: the wet bulb temperature for 50°C at 5% humidity is 33°C, and at 99% humidity it's 49.7°C. So 53°C is trouble no matter how dry the air is.

Sounds very similar to Chapter 1 of Kim Stanley Robinson's novel, "The Ministry of the Future".

Yes, I agree with you. 20 million died there, right?
