As Arctic sea ice vanishes at alarming rates, startup Real Ice deploys pumps to spray seawater onto thinning ice sheets, aiming to create thicker, longer-lasting ice. This controversial geoengineering approach faces scientific skepticism about scalability and environmental impact.

As global emissions continue to rise despite mitigation efforts, scientists are turning to stratospheric aerosol injection—a technique inspired by volcanic eruptions—as a potential short-term climate intervention. This article explores the science behind deliberately cooling Earth, the phased trial framework modeled on clinical drug testing, and the technological challenges of deploying sulfur dioxide at scale. What are the implications for renewable energy, agriculture, and global policy if we dim the sun?
