[W]e have no non-radical solutions left to deal with climate change… either we face a radical climate catastrophe or we must radically shift our economy and modes of social organisation away from the current fossil fuel economy
That was the message given by David Spratt, author of Climate Code Red, and Ian Dunlop, who formerly chaired the Australian Coal Association but has since become a climate activist, at the Breakthrough 2014, National Climate Restoration Forum, last month in Melbourne, reported by Green Left Weekly.
One source of radical solutions is the growing geoengineering industry. Recently proposed methods for the sequestering of carbon dioxide include ants, iron sulfate and artificial trees .
Debate continues about when and how geoengineering might ever be deployed. Amongst environmentalists, support for geoengineering methods is low. Green Left Weekly explains:
as Clive Hamilton describes in his book Earthmasters, geoengineering technologies are supported by leading climate denial organisations and by the fossil fuel industry. This is because they seem to offer a way that fossil fuel use can continue unabated. The side effects of these technologies could be brutal: for example, severe drought in Africa and Asia. Moreover, if spraying was stopped, temperatures would rise rapidly, leading to even more devastating impacts.
Will regulation help? Green Left Weekly argues that governments have been unable to regulate fossil fuel industries effectively, and that they will be unlikely to succeed more here.
It is fruitful to look at comparisons with human genetic or biological modification, or human bioengineering.
Both are complex systems affecting life processes.
