Across the American South, from Texas to the Carolinas, seventy million people find themselves beneath a heat dome that has settled over the region with the indifference of geological time.

It is a reminder that climate is not backdrop but protagonist, and that the infrastructure of modern life was built for a world that may no longer reliably exist.
