    Well…

    If you reduce car dependence and tear up lanes from stroads to plant trees, that is a form of carbon capture that could work. The artificial carbon capture is bollocks though.

    The last two graphs are fantastic!

    They show carbon capture is basically nothing, I’m spite of optimistic predictions. They also show that solar electricity generation has exceeded every estimated growth.

    So this article looks creative and all, but it was damn near impossible to read because of the creativity

    Having said that, there is still more to this

    Doing carbon capture while still having CO2 emitting power generation is dumb because of losses. No machine is 100% efficient, many are much, much less. You either end up generating 100 units of CO2 for every 30 or so that you capture, or if you use solar, some other electrical system will use power that was generated with 100 units of CO2 for every 30 you capture…

    First we need all energy generation done with renewables.and or nuclear

    Once all that is done, you could start capturing and converting to non gaseous forms. Whatever the product is, you still need to store it somewhere

    The bigger issue, though, is that the extra CO2 in the air is there because of power we generated at some point over the past 200 or so years. If we want to get back to pre industrial levels of CO2 in the air, we need to spend at least the same amount of electricity that we have gotten from burning fossil fuels for the past 200 years. Add in conversion losses, and you can probably double that. If you want to convert it into something else for more reliable storage you might double THAT again as well. Add in the required energy to build all those capturing and conversion infrastructure, and you can possibly double it again.

    We generate much more electricity now than, say 100 years ago, but still; Even if we dedicate 50% of the world’s energy budged to carbon capture, we’ll still be spending half our energy budged to capturing carbon for many many decades, if not multiple centuries.

    One huge thing we could do much easier is to just stop generating CO2. How has that gone? It’s 2026 and we’re pumping CO2 into the atmosphere at higher levels than ever before. If we can’t even do the easy solution, how are we ever supposed to do the hard one?

    Humanity has for centuries allowed a tiny % of humans to fuck the planet and all of us and I am unsure if we’ll ever be able to unfuck it at all at this point
