What about carbon capture in the soil? Genuine question, I'm not at all familiar with the science.

- wizzwizz4 5y agoIirc, that's an old forest thing, and goes away pretty much as soon as the trees do.
- colechristensen 5y agoDepends on the forest and specific local ecology. Planting forests definitely is a carbon sink, but the carbon goes into the living biomass. Whether or not you get long term buildup of soil carbon just depends. In other words there’s a sizable one time bonus to planting forests and a conditional long term continuous sink. People tend to simplify one way or the other.
- EdwardDiego 5y agoI was thinking about peat soils - as we know, they're great at preserving organic matter thanks to high acidity, to the extent that they're dug for fuel. A lot of peats in my country have been drained (and the drainage requires continual maintenance) for pasture, but well, it's rather hard to farm without harming the environment.[1] But I'm assuming that healthy peat bogs are fixing carbon/ritual sacrifices in a net-negative manner until someone digs it up and burns it. I just wonder if allowing peatlands to revert for carbon credits would offset the loss of the pasture.

- titzer 5y agoJust a PSA, the term "carbon capture" people are throwing around now almost always means capturing CO2 at emission sources like fossil fuel-fired power plants. It generally does not mean capturing CO2 from the air at large. There really is no viable technology for that. Except trees.
