Tldr: solar engineering by blocking sun at L1 with big bubbles.

This doesn’t reverse anything. It slows warming, but doesn’t de-acidify the oceans or decrease the CO2 in the atmosphere.

Solar engineering is a radical, risky Hail Mary that should only be considered as a stopgap emergency measure provided emissions are being managed. Without that the problem is not solved and if the mitigation (sulfur, bubbles, whatever) is removed the snap back will be extreme.

We need to stop putting CO2 and methane in the air and start removing what’s there, period
