I don’t understand how solar geoengineering is even on the table. Wouldn’it fuck up agriculture – and plant life in general – even more than it already is? Isn’t it a choice between a famine because of the climate or a famine because the sun is blocked off?
There is a fair bit of risk. Its on the table because we need to be finishing the fossil fuels phase out around now, not starting it
Solar geoengineering would alleviate the symptoms and so take pressure away from treating the root cause. And so I’d say that it would make things more expensive in the long term as the underlying illness would continue to get worse, festering under that bandaid.
