Ways through
Two routes, each starting somewhere different. Nothing here is a prerequisite for anything else, and every question stands on its own. A stop opened from a route carries it: the foot of the question offers the next one.
Downward
From the crust to the core, and the life that turns out to live kilometres into the crust and beneath the Antarctic ice.
Take this routeThe planet’s bad days
Ice at the equator, a mass extinction, the rhythm of the ice ages, two thresholds that may already be behind us, and the layer we are leaving.
