Dimming the Sun

Earth stands at a tipping point. As we fail to curtail emissions fast enough, our planet stares down a cascade of imminent, catastrophic, and irreversible disaster triggered by climate change. Yet a potent technology already exists to buy us more time: solar geoengineering. Through methods such as atmospheric aerosols, human-generated cirrus clouds, and solar sails, we humans canat least in the short termslow the Earths warming. Should we? Award-winning science writer Thomas Ramges Dimming the Sun is his provocative, informative, urgent, and necessary exploration of this intriguing stopgap solution. Ramge shows us how the science works, what the risks areboth geophysical and politicaland how the international community might come together to agree on and regulate a safe and effective plan for geoengineering. And while he identifies the unknowns about the technology that remain, he believes this very uncertainty demands our full attention. With time to avert the worst of climate change rapidly running out, he makes a forceful case that the most responsible course of action is to dramatically increase research on solar geoengineering nowbefore its too late.
