A study has suggested spraying diamond dust into the atmosphere to cool the Earth. It explored the idea of using five million tons of pulverised diamonds annually to reflect sunlight and reduce global temperatures. If sustained over 45 years, the researchers say this could cool the Earth by nearly 2.9 degrees Fahrenheit. However, this will reportedly cost nearly $200 trillion.
