@mustapipa@scicomm.xyz #Venus had volcanism so it can be assumed to have plate tectonics too. Does this mean that if we decrease amount of sunlight reaching #Venus by say 20%, we can carry out Geoengineering to make it habitable once again? We will off course need bacteria and other microorganisms that thrive in heavy CO2 atmosphere.

@welkin7@mstdn.party I do not think it would be that simple. In any case, reversal of the runaway greenhouse state requires a method of removing carbon from the atmosphere, which is not possible without weathering due to rainfall, which is not possible due to the heat. It is a vicious cycle, and when turned on for a planet, reversal seems rather impossible. The exact details of how the runaway started are up for debate though.
