    The problem is stuff like concrete… the way to make new concrete emits a shitload of CO2, whether or not you use electricity or fossil fuels. So we either need to find an alternative to cement or we need to capture all that CO2.

      Plus, it’s not like carbon capture would be used in a vaccuum. It would be to supplement all other strategies

      It is useless to capture it. It will diffuse back to the atmosphere at some point in the future. It must be transformed. Or we should stop producing it

        Except we have clear evidence that if it’s stored properly it will stay there for millions of years. The fossil fuels (mostly) did not emit carbon into the atmosphere in the millions of years between dinosaurs / algae and now.

          Sorry, but I don’t understand your point. You are made primarily of C, and you don’t emit C either, other than C that you get from food and you transform in CO2, luckily for you. Your C is safely stored in a variety of forms that do not contribute to greenhouse effect, until transformed by bacteria. C, fossil fuels and CO2 are very different things
