what poor and prosperous households do in a heat wave when they have access to air conditioning.

In a poor household, you wait, they found through science, they delay turning on the air conditioner four to seven degrees more of heating before they start to use the air conditioner.

And that create adverse outcomes.

If you have an asthmatic in the house, an old person,

You're endangering their lives.

And that's just a little tiny microscopic fractal example of this powerful real phenomenon that there's a divide in vulnerability.

And it's not just based on where you live.

This is families in like Pittsburgh.

Mm-hmm.

We're not talking about Botswana.

And so that divide in capacity to deal with environmental stress is something you can really work on.

And it gets hidden in all this talk of climate crisis.

And the second condition, 8 billion.

And one tiny little last example, you mentioned Jakarta at the beginning.

It's really valuable to look around the world at places that are sort of leading indicator places, whether it's sea level rise or heat.

And you could do that.

Jakarta is sinking like a foot a year, literally a foot a year.

It's some insane number from withdrawing groundwater, from gas withdrawal.

It's a delta.

It's sediment.
