Carbon dioxide emissions can turn dry places into deserts, and that’s hard to undo.

    And there is no version of averting the worst possible results of climate change that does not include CCS and DAC, but I’ve never seen a remotely serious model that relies on either of them being used to do more than bump something a percentage point or two one way or the other.

        I am innately skeptical of tech startups with huge promises and extremely limited quantifiable field results. Dumping huge quantities of chemically-reactive sand onto global coasts just sounds like it has major potential downsides.

        It’s promising. There’s lots of promising DAC methodologies. We should pursue them.

        I find stuff like the CarbonCure/Heirloom partnership more compelling, and even that I think would be foolish to bet heavily on compared to rolling out more wind/solar/EGS along with grid enhancements.
