Geo engineering solutions have been proposed for a while. They were particularly popular in the public imagination back when there was fear of a new ice age. They are less popular now given the belief that there is something we can do to change our CO2 emissions. I suspect the next major climate conference will include discussion on this topic given the present effects of global warming and our inability to control carbon emissions in any region for the last 30 years.
