Context: Recent studies suggest that spraying diamond dust into the Earth’s upper atmosphere could help reduce global temperatures by up to 1.6°C over the next 50 years.
Key Features:
- Reflective Properties: Diamond dust reflects sunlight and heat back into space, helping to cool the planet. Its small, fine particles would stay airborne for extended periods and are unlikely to clump together, which would otherwise trap heat.
- Chemically Inert: Unlike some other methods, diamond dust wouldn’t lead to harmful side effects like acid rain due to its inert chemical nature.
- Challenges: Despite its potential, the high cost and logistical issues involved in producing and dispersing diamond dust make large-scale implementation difficult.
