  •  Plant trees (14+ / 0-)

    Nothing is going to take CO2 out of the atmosphere except more plants.  Plants are what brought the CO2 level down to where it is, and man is not going to invent some new technology to take the place of plants.  

    Deforestation is one of the great contributors to CO2 rise, and reforestation is what we should be working on to get the CO2 out of the atmosphere and back into the ground.  

    Had we been doing this all along, planting forests, burying biochar, tying fossil fuel use to planting more trees, we might not be in the predicament we are in.  

    •  We need more plants in general (4+ / 0-)

      I have to wonder whether trees are the best way to scrub carbon.  There's probably other plants that are more efficient.

      The revolution will not be televised. But it will be blogged, a lot. Probably more so than is necessary.

    •  I heard that certain grasses are even more (6+ / 0-)

      effective than trees, especially prairie grasses that have very extensive roots. One neglected area is to grow halophytic (salt-tolerant) plants in arid regions and water them with sea or brackish water. Apparently there are about 6000 species of this type of plant. One would think that the shores of the Arabian gulf, etc would be useful.

      •  Not just grasses with extensive roots. (6+ / 0-)

        Go back to grass-fed animals for what meat we do eat, and have responsible numbers of animals per acre grazed.

        One of the details in Omnivore's Dilemma is that the farm the author visited had gotten its soil quality back because of an interesting feature of grass: it seeks to maintain a certain root to leaf area ratio. When an animal grazes, the grass abandons the extra root mass. It regrows the root matter as the above ground leaf grows back, BUT all the carbon for both come from the CO2-O2 cycle, not the ground. The carbon from the old root just sits there, along with all the other nutrients in it.

        That was just everyday southeastern pastureland 'nature let it grow' field grass. The farmer never seeded it; it was there when he started.

        Graze sustainably, and the grass gets nibbled again right at the point the recovery growth slows down... which maximizes the calories taken in by the livestock but also (and the book didn't point this out but it follows) maximizes the abandoned root material's mass and carbon content.

        It wouldn't be as fast as making terra preta, but it might still be a source of carbon sequestration over time, while still allowing for (a lesser amount of) dietary meat.

        Prayers and best wishes to those in Japan.

          fed animals are very good. They raise them in coastal areas around here and can get premium prices for them (or did before we all went  broke and started eating beans, thereby adding to the methane problem).
