The Impact of Heat on Cities and Towns

With heat rising one thing that's been noticed is in every city you're hitting new peaks. Chennai is reporting temperatures it has never seen and the bud which started the heat action plan complains that it's not effective anymore. How much could this affect how our cities are as in you spoke about how the GDP itself could potentially fall with this. Could you talk about that aspect? I feel like there has to be a balancing act. But ultimately you're looking at a very different country if you take adaptation seriously.
