Generally speaking, anthropogenic climate change doesn’t come at us like some Pacific Rim Kaiju monster, leaping suddenly into view from the watery depths. It’s slow and confusing and hard to observe on a day-to-day basis. But that doesn’t mean that we don’t have some nasty — and sudden — surprises in store. A new report by the National Research Council looks at the social and ecological dangers that could lie ahead.

The report has a Hollywood-friendly two-part title: “Abrupt Impacts of Climate Change: Anticipating Surprises.” And like Hunger Games: Catching Fire, this new release is also a sequel — to the NRC’s 2002 report of the same name, subtitle: “Inevitable Surprises.”

And what kinds of inevitable surprises should we be anticipating?
