To keep global temperatures from rising too quickly, we need to re-engineer our society away from fossil fuels. A 2015 study calculated that to rein in warming, about 80 percent of global reserves of coal, 50 percent of natural gas reserves and 33 percent of the world’s oil must be left unused. Action is required on multiple levels — government, industry, and individuals — and across multiple systems, including energy, transportation, housing and food. We need to do all of the things, says Jonathan Foley, executive director of Project Drawdown, whose organization has identified more than 80 climate “solutions” available now. These range from renewable energy technologies to plant-based diets to mass transit. “To get to drawdown, we need them all,” Foley says.
