Geoengineering the Planet

I have writtena blog about geoengineering which is published by the One World Column at http://oneworldcolumn.blogspot.co.uk/

In it I argue that we may be forced to undertake some geoengineering of the planet because of the risks of runaway climate change being triggered by the release of methane in the Arctic. It's a controversial subject and I would be really interested to get people's feedback on the argument I have made. Please take a read and leave me your comments either there or on this page.
