The High Price of a Controversial Climate Solution

Professor Ted Parson discusses the controversial climate solution of stratospheric aerosol injection, which involves releasing sulfur dioxide particles into the upper atmosphere to reflect sunlight and cool the Earth's temperature by 1 degree Celsius within a few years. While it could help prevent catastrophic climate disasters, critics warn of potential harm to the ozone layer and respiratory illnesses. Many leaders are reluctant to embrace this approach as it is not a permanent solution and may deter efforts to reduce greenhouse gas emissions.
