How hard would it be to stick a sufficient amount of dust in the atmosphere to give us a better handle on controlling the climate?

- dalke 11y agohttps://en.wikipedia.org/wiki/Climate_engineering#Solar_radiation_management https://en.wikipedia.org/wiki/Climate_engineering#Solar_radi... A full nuclear exchange is predicted to lower the temperature by about 20 °C. That depends on 7 billion tons of dust.
- hugh4 11y agoInteresting. So although that particular mechanism is undesirable it seems like cancelling out a couple of degrees of warming is well within our capabilities.
- dalke 11y agoEven if you are comfortable experimenting with the entire Earth's biosphere, global warming is only one aspect of increased carbon emissions. As that climate engineering page points out: > These methods would not reduce greenhouse gas concentrations in the atmosphere, and thus would not seek to address problems such as the ocean acidification caused by CO2.
