       https://www.theguardian.com/environment/2023/nov/19/carbon-dioxide-direct-air-captureDirect air capture of CO2 is useful in principle. But since it takes a lot of energy, would it reduce atmospheric CO2 more than reducing fossil fuel generation by that same amount of energy?

       @rms should we just have to plant more trees?

       @rms Perhaps, as renewables take over, the delicate balance will shift somewhat - won't there be periods and locations where there's a surplus of energy even transmission and storage won't cope with (at least for a long time), and so the surplus can be used for things like desalination and direct carbon capture without a negative effect elsewhere?

       @rms It's only worthwhile if is done using surplus carbon free energy.In effect it could only run during low load times 6-8 hrs a day.
