Long before the rising waters from Greenland’s glaciers displace the desperate millions, [glaciologist Jason Box] says more than once, we will face drought-triggered agricultural failures and water-security issues—in fact, it’s already happening. Think back to the 2010 Russian heat wave. Moscow halted grain exports. At the peak of the Australian drought, food prices spiked. The Arab Spring started with food protests, the self-immolation of the vegetable vendor in Tunisia. The Syrian conflict was preceded by four years of drought. Same with Darfur. The migrants are already starting to stream north across the sea—just yesterday, eight hundred of them died when their boat capsized—and the Europeans are arguing about what to do with them. “As the Pentagon says, climate change is a conflict multiplier.”
His home state of Colorado isn’t doing so great, either. “The forests are dying, and they will not return. The trees won’t return to a warming climate. We’re going to see megafires even more, that’ll be the new one—megafires until those forests are cleared.”
However dispassionately delivered, all of this amounts to a lament, the scientist’s version of the mothers who stand on hillsides and keen over the death of their sons. In fact, Box adds, he too is a climate refugee. His daughter is three and a half, and Denmark is a great place to be in an uncertain world—there’s plenty of water, a high-tech agriculture system, increasing adoption of wind power, and plenty of geographic distance from the coming upheavals. “Especially when you consider the beginning of the flood of desperate people from conflict and drought,” he says, returning to his obsession with how profoundly changed our civilization will be.
