Apocalyptic Climate Change

2080: At a remote site on the edge of the Arctic Circle, a group of scientists, engineers, and physicians gather to gamble humanity’s future on one last-ditch experiment. Their goal: to make a tiny alteration to the past, averting a global catastrophe while at the same time leaving recorded history intact. To make the experiment work, they just need one last recruit: an ageing schoolteacher whose late mother was the foremost expert on the mathematics of paradox. 2028: A young woman goes into surgery for routine brain surgery.

Raised in a privileged community of wealthy survivalists on an idyllic, self-sustaining Oregon ranch, Marlo has always been insulated. The outside world, which the ranchers call “the Disaster”, is a casualty of ravaging climate change, a troubled landscape on the brink of catastrophe. For as long as Marlo can remember, the unknown that lies beyond the borders of her utopia has been a curious obsession. But just as she plans her escape into the chaos of the real world, a charismatic new resident gives her a compelling reason to stay.

In an unspecified future, the United States' borders have receded behind a salt line - a ring of scorched earth that protects its citizens from deadly disease-carrying ticks.

Few have any reason to venture out of zone, except for the adrenaline junkies who pay a fortune to tour what's left of nature. Those among the latest expedition include a pop star and his girlfriend, Edie; the tech giant Wes; and Marta, a seemingly simple housewife.
