"The same week that news of He’s experiments came out, the journal Nature ran a story about a team at Harvard that is planning the first real-world experiments in geoengineering — releasing particles of calcium carbonate into the high atmosphere over part of the southwestern United States. It’s part of a project to develop a way to block sunlight and hopefully reduce the global average temperature (but not by too much). The tests could start as early as next year."

"Earth is warming at an unprecedented rate due to anthropogenic carbon dioxide emissions. This was recognised at the 2015 Paris Climate Convention (COP21) in 2015 who agreed to limit warming at 2°C or less. Emission reductions are essential to help mitigate further warming, but we are already likely to exceed this 2°C warming. In response, COP21 recognised that some form of ‘negative emissions’ is required to stay within the 2°C warming target."
