When does it become too hot?

In the last couple of weeks I've read about the impact of rising sea levels in the Florida Keys and now this week, we have the highest recorded temperature on Earth.
Jacobabad crossed the 35C wet bulb threshold in July 1987, then again in June 2005, June 2010 and July 2012. Each time the boundary may have been breached for only a few hours, but a three-day average temperature has been recorded hovering around 34C in June 2010, June 2001 and July 2012. The dry bulb temperature is often over 50C in the summer.

I can't even begin to imagine what it would be like to have to work in such heat. However, it's widely predicted that many more parts of the world will need to deal with such temperatures over the next few decades.  

At what point though does drastic action need to be taken instead of being acknowledged?

When does it simply become too hot for people to safely live their lives?

Clearly, we're already there.
