The world is getting hotter. We must adapt to it equitably.

Shade could be a low-tech solution to our heat problem, but inequalities make it a fraught commodity.

Ultimately, to solve global warming, we must drastically reduce greenhouse gas emissions. Part one of this month’s cover story package addresses that challenge.
