It's far easier to avoid burning fossil fuels than it is to clean up CO2 emissions once they're in the Earth's atmosphere. But the world no longer has the luxury of choice—drastic emission reductions and rapid CO2 removal and storage will both be necessary to avoid the worst impacts of global heating....
