Posted this in another thread, but rather than hijack it I will start a new one: Something that I thought of during the COSMOS show the other night...is anyone working on a method to remove CO2 from the atmosphere? We have seen all sorts of anti-warming ideas go out (smoke, giant umbrella, millions of tiny mirrors in space) but has there been any work on artificial plankton or a material that absorbs CO2? We have talked endlessly about CO2 production and I hope this doesn't turn into that conversation or a debate of the role CO2 even has. But if we are putting that much CO2 into the air, is there any research into recapturing it at an industrial level? Say we stop all CO2 production this afternoon, assuming it takes a while to break CO2 back down, are we working on a way to counter the already released stuff?
