This article is mostly about geo-engineering technology, but I can't help but feel like the technological side of the venture is the easiest part. Who is going to make the go/no-go decision? The UN? By majority vote? How much do we lower the temperature by? I can't imagine an agreement being reached on something like this in my lifetime. For this reason I think we're far more likely to see this problem 'solved' by renegade geo-engineering efforts like what Russ George did (http://www.guardian.co.uk/environment/2012/oct/15/pacific-iron-fertilisation-geoengineering http://www.guardian.co.uk/environment/2012/oct/15/pacific-ir...) and that has me deeply worried.
