As the threat of climate change has gone from theoretical to apparent, proposals for a more aggressive attempt at mitigation through geoengineering have gained currency in some scientific corners, drawn skepticism or outright opposition in others. Prospects for geoengineering would likely improve in inverse proportion to prospects for nations to hit their emissions targets to slow, then reverse the warming of the planet.
