Phys.org: Future of planet-cooling tech: Study creates roadmap for geoengineering research
„Simply reducing greenhouse gas emissions probably is not going to be sufficient for the planet to escape catastrophic damage from climate change, scientists say. Additional actions will be required, and one option is solar geoengineering, which could lower temperatures by methods such as reflecting sunlight away from the Earth through the deployment of aerosols in the stratosphere. However, the prospect of experimenting with the Earth’s atmosphere has left some people skeptical of the process.“
