A soil-science revolution upends plans to fight climate change
There is one way of storing carbon in the soil for the long term: biochar[0].  Biochar is organic matter heated anaerobically (pyrolysis) until it turns into something like charcoal.  Biochar is stable for a long time.  You can then bury that in the soil... it seems to improve the soil by providing surface area for soil micro-organisms and to store nutrients.  This could be done on a very large scale, and pyrolysis can actually be energy positive because you can burn the hydrogen that's released to perform the pyrolysis and still have energy left over.<p>This may be one of our best options, and we should accelerate more research in that area.<p>[0] <a href="https://en.wikipedia.org/wiki/Biochar" rel="nofollow">https://en.wikipedia.org/wiki/Biochar</a>
