It seems that some of the most perceptive brains in society have given up on an effective response to climate change. Stephen Hawking infers that mankind should colonise distant planets. James Lovelock thinks the remnants of humanity will seek refuge on the tropical shores of the Arctic. Scientific data now strongly suggests that physical and biological changes in the planet are increasingly greater than those defined by the modelling in the most recent Intergovernmental Panel on Climate Change (IPCC) report. Despite the steadily rising levels of carbon dioxide in the atmosphere, even countries expressing commitment are having little impact compared to the huge task in hand. Democratic governments continue to approve projects that will make reductions difficult if not impossible.
