How Cooling the Planet with Geoengineering Would Upend Climate Economics

How Cooling the Planet with Geoengineering Would Upend Climate Economics

As global temperatures rise, the use of reflective aerosols to cool the planet — perhaps by a nation acting alone — becomes a more realistic possibility. In a new working paper, Yale SOM’s Kelly Shue and Samuel Hartzmark of Boston College model how this type of geoengineering fundamentally shifts the economics of climate change, altering incentives for renewable energy, fossil fuels, and carbon removal.
