Professor John Quiggin writes in Inside Story (20.12.14): ‘The task before the world is to decarbonise the global economy by 2050, and it seems quite likely that global negotiations will continue up to that date and perhaps (given the need for negative net emissions after 2050) beyond. Bismarck is supposed to have remarked that “laws are like sausages; it is better not to see them being made.” The same is true, in spades, of global climate policy. Nevertheless, depressing as the process may be to watch, progress is being made. We still have a good chance of stabilising the global climate, even if the path we take is messy and unnecessarily costly.’
