    I feel like there’s a lot of these carbon-sequestration companies that are selling absolute poppycock and getting billions in funding, and very little actual oversight. They’re doing this song and dance with “carbon credits”, and eventually someone’s going to peek behind the curtain and blow their cover.

    I haven’t seen one carbon-sequestration entity yet, besides those that are focused around planting trees, that have actually shown any real results other than vague handwavey bullshit. Like the ones saying they’re capturing it out of the air and pumping it underground – awfully convenient that nobody can fucking verify that it’s actually happening eh?

    The amount of CO2 & methane that needs to be removed from the atmosphere, now, to undo 5-9C of inevitable planetary heating…


    Evolution of global temperature over the past two million years https://www.nature.com/articles/nature19798

    Factoring in the excess methane, only ( not including other greenhouse gasses ), that we’re producing, brings it up to 8-9C planetary heating, using methane’s 20y CO2 equivalent, & 1.3 to 1.4ppm atmospheric methane added by us.


    … is measured in the billions or trillions of tonnes.

    I’m beginning to think that all the “we can ride this” idocy should be considered a categorical psychiatric delusion.

      Most locations aren’t like that; they’re injecting into oil and gas deposits with the risk of subsequent leakage

      Enhanced rock weathering is very cool if it can be made to work at scale. Most examples have issues with needing a lot of energy to mine and pulverize rocks

        with the risk of subsequent leakage

        That risk is like telling:" humanity will go down due to a eruption of a super vulcano"

        But i agree carbfix is no solution for global scales.
