Diamond Dust Geoengineering for Global Warming
A study in Geophysical Research Letters proposes using diamond dust for Solar Radiation Management (SRM) to reduce global warming. By spraying five million tonnes of diamond dust annually into the upper atmosphere, researchers aim to lower temperatures by 1.6°C. Diamonds outperformed six other compounds in reflecting solar radiation efficiently. While SRM is inspired by natural phenomena like volcanic eruptions, concerns about cost, ecological impact, and governance remain. This method could significantly mitigate warming, but more research is necessary to assess its feasibility and safety.
