Peter Schwartz is a compact man with lively eyes and an air of importance. A rocket scientist by training, he also researched climate change at Stanford Research Institute. Drawing on knowledge of past climate shifts, Schwartz spun out the most dire scenario he could defend scientifically. Starting tomorrow, he assumed, the world warms faster than even the most alarming predictions — by as much as half a degree a year. The heat sets off a chain reaction. Droughts spark catastrophic fires, which release still more heat-trapping CO2 into the air. Increased water vapor in the atmosphere traps still more heat. Super-storms break dikes in Europe, and coastal cities such as the Hague in the Netherlands become uninhabitable. Levees break in California, creating an inland sea and disrupting the water supply in Los Angeles. Then Schwartz drew upon one of the least intuitive impacts of global warming: the idea that turning up the world's thermostat could lead, perversely, to a cooling crash. As high temperatures melt ice at the North Pole, the runoff of cold water could disrupt the Gulf Stream. This conveyor of warm water is what gives Europe its temperate climate; flip off the Gulf Stream, say climate scientists, and the continent hits a deep freeze. Mainstream projections say this shouldn't happen before 2100; Schwartz envisioned it happening in 2010. As Europe plunges into a Siberian chill, the rest of the globe continues to sizzle. Sea levels rise. Megadroughts strike worldwide, spawning dust bowls and destroying crops. The world suffers from "catastrophic shortages of water and energy supplies." Earth's "carrying capacity" — militaryspeak for the number of people it can feed — drops radically. Given the deadly shortages of food, civilization erodes as "constant battles for diminishing resources" become the norm. "Every time there is a choice between starving and raiding," Schwartz writes, "humans raid." America turns inward, attempting to shield itself from the flood of refugees from the drought-stricken Caribbean. Hostilities arise between the U.S. and Mexico as both countries jockey for water from the Colorado River. Europe considers invading Russia for its food, and Japan eyes Russia's oil. Africa starves. Bangladesh is unlivable. Famine drives chaos in Asia. "Envision Pakistan, India and China — all armed with nuclear weapons — skirmishing at their borders over refugees, access to shared rivers and arable land," the scenario suggests. "In this world of warring states, nuclear-arms proliferation is inevitable." "Once again," the report concludes starkly, "warfare would define human life."
