I have a great respect for National Geographic. I’m a card-carrying member with an annual subscription, and I appreciate the balance, depth and understanding they bring to revealing the links between the natural and human world.
So the latest issue had prepared me for a recent debate at the Royal Society in London which examined the question of the Science of Change in the Arctic. It painted a stark and disturbing picture of our planet’s future in terms of the impact of global sea level rise on coastal cities. It dramatically brought home the message that a fossil fuel-driven civilisation has profoundly altered the planet, which by 2070 will put some 150m people and US$35 trillion worth of assets in the world’s coastal cities at risk from flooding. Our desire for carbon intensive energy has raised sea level by 60mm since 1994 and the draft fifth IPCC report predicts a one metre rise by the end of the century. That is a lot of coast underwater.
