Stratospheric Solar Geoengineering

Dr. David Keith believes in intentionally releasing sulfur dioxide into the stratosphere to lower global temperatures and blunt global warming. This controversial idea of stratospheric solar geoengineering is met with hope and fear. While proponents see it as a potential solution to reduce temperatures before transitioning away from fossil fuels, opponents fear unpredictable calamities, environmental disruptions, and health risks associated with the technology.
