GEOENGINEERING RISK.

The article "GEOENGINEERING RISK" discusses the proposal of using sulfur dioxide (SO2) to combat global warming by reflecting solar radiation back into space. The chemical reactions involving SO2 can lead to the formation of sulfuric acid, which can cause acid rain and harm forests that absorb carbon dioxide. The article highlights the need for aircraft capable of delivering sulfur dioxide into the stratosphere, but acknowledges that the construction of such planes would contribute to carbon emissions. The potential risks and consequences of geoengineering are also mentioned, with suggestions for alternative approaches such as releasing reflective dust from a rocket. [Extracted from the article]
