Geoengineering: cooling Earth with artillery shells

The video discusses a geoengineering proposal published by the National Academy of Science. It involves using artillery shells and naval rifles to disperse UV reflective alumina into the stratosphere. The plan includes setting up stations on land or at sea to fire projectiles continuously for most of the year. Alumina, similar to sulfur dioxide, can reflect ultraviolet light, potentially impacting climate control.
