You are aware that "temporarily" in this context is the lifespan of a tree, right? Trees live anywhere from several decades to 20+ centuries, and their remains, once broken down, provide nutrients to the soil so more trees can grow.

Also the tree is not capturing carbon, instead emitting, half of the year if not planted in the optimal places near the equator. And it's carbon neural or negative once almost fully grown. Hence why you need to cut them down and bury.

  That's not true. Trees metabolize year round, and they literally breathe CO2.

    Once a tree is fully grown it essentially stops capturing CO2.
    - pmiller2 6y ago
      Again, that is not true. Trees need CO2 for respiration. Basic biology, folks.
      - adrianN 6y ago
        Basic biology should tell you that the only thing that counts for carbon capture is biomass added. Anything that the tree does that doesn't permanently add to its mass can't capture carbon permanently. Hence, once a tree stops growing, it stops capturing carbon. It still respirates because it does things that require energy, but any carbon it captures doing so is released fairly quickly again, e.g. when the leaves it produced in spring fall off and rot. Of course many trees keep growing a little even after they reach maturity, but the rate of growth is minuscule. A mature stable forest stores a large amount of carbon, but it hardly captures any more.

        Well, you know what? Plants reproduce, too. And, BTW, trees don't stop growing. They keep adding mass in their trunks. Literally the first google hit for "do trees stop growing": https://earthsky.org/earth/what-makes-a-tree-stop-growing https://earthsky.org/earth/what-makes-a-tree-stop-growing Edit: guess what? They even grow faster as they get older! https://www.npr.org/2014/01/16/262479807/old-trees-grow-faster-with-every-year https://www.npr.org/2014/01/16/262479807/old-trees-grow-fast...

        That is a different point. Anyway, the land we have is limited. You literally can't cover the planet in one big forest to capture the gigatons of carbon we have released. You have to do active forest management and store the carbon somewhere stable, for example as biochar.

        Reducing the numbers of those pesky humans would help.
        adrianN 6y ago
        You can't reduce the number of humans quickly enough without a genocide.
        pmiller2 6y ago
        Doesn't mean we still don't need to reduce numbers for long term sustainability.

        That's the one thing climate change is good at once it gets bad. I thought we wanted to avoid this?

    They breath oxygen, they "feed" on CO2, once fully grown they need less food and that changes the balance
    - pmiller2 6y ago
      No, that is wrong. Plants emit O2, and consume CO2. This is called respiration.
