Scientists propose injecting diamond dust into atmosphere to combat global warming

Scientists have proposed a new method to combat global warming by injecting 5 million tons of diamond dust into the atmosphere each year. This approach could potentially cool the Earth by up to 1.6 degrees Celsius. The idea is based on natural volcanic eruptions, which release ash into the atmosphere. Unlike other geoengineering methods, such as sulfur injections, diamond dust is believed to have fewer harmful side effects and a longer-lasting cooling effect. However, the plan comes with a hefty price tag, estimated at $200 trillion over the century. Researchers are still assessing its effectiveness compared to other solutions.
