Overview

• Keith's plan involves releasing sulfur dioxide into the stratosphere to reflect sunlight and lower global temperatures.
• The technique draws inspiration from the cooling effect of volcanic eruptions, such as the 1991 Mount Pinatubo event.
• Proponents argue it offers a rapid, cost-effective solution to global warming, potentially saving millions of lives.
• Critics warn of unpredictable consequences, including climate disruption and health risks from sulfur dioxide.
• Despite opposition, the University of Chicago supports Keith's research, fueling further controversy.
