As soon as I started reading this article, I thought of this thread. :think: https://www.theguardian.com/environment/2013/oct/08/climate-engineering-geoengineering-climate-change
i was rather surprised by some reactions to biochar as some people think it is too good of a solution. i'm not quite so sure of that in terms of one thing as i would think that having a lower albedo for disturbed soil would warm things up even more. yet, if biochar were buried or used in areas that are not disturbed it at least is a more preferable way of getting CO2 tied up for a long period of time. if it did become a problem longer term, the solution would be easy enough to just return to carbon depleting soil uses. we have those technologies down in spades...
A good review of the Australian author Clive Hamilton's book "Earthmasters: the Dawn of the Age of Climate Engineering". Be afraid. https://www.resilience.org/stories/2013-11-27/review-earthmasters-the-dawn-of-the-age-of-climate-engineering-by-clive-hamilton
