Injecting Diamond Dust: A New Approach to Cooling the Earth
The study examined seven materials, including calcite, aluminum, silicon carbide, and sulfur dioxide.
Scientists are trying to find ways to cool the planet as it approaches a critical point.
The Earth is getting warmer, and we can see the effects through more intense and frequent extreme weather.
Scientists are trying to find ways to cool the planet as it approaches a critical point.
A new study suggests that injecting diamond dust into the atmosphere could help cool the Earth.
A team of scientists used advanced climate models to compare different materials that could reduce global warming.
As climate change gets worse, researchers are looking for new ways to cool the planet.
While carbon capture has been suggested, the team believes we may need stronger actions to reflect sunlight and heat back into space.
The study examined seven materials, including calcite, aluminum, silicon carbide, and sulfur dioxide.
Surprisingly, diamond dust was found to be the best option.
Diamond particles reflect the most light and heat. They also stay in the air longer and don’t clump together.
Unlike sulfur dioxide, which can cause acid rain and harm the ozone layer, diamond dust is safe for the environment.
The study suggests that injecting 5 million tons of synthetic diamond dust each year could cool the Earth by 1.6°C over 45 years.
However, there is a big problem: the cost. This solution would require about $200 trillion.
While the diamond dust idea is new, it shows how complicated and expensive geoengineering can be.
