Our Common Cause: Climate Change − the Danger is Now from Green Left Weekly 24 January 2009 The fate of advanced human civilisation − and perhaps of our species itself − hangs in the balance. Fuelled by human-induced greenhouse gas emissions, global warming is advancing at a pace inconceivable to scientists just a few years ago. The complete melting in late summers of Arctic sea ice − something that scientists used to predict for the final decades of this century − is now widely expected by 2013-15. As the highly reflective ice is replaced by dark water, much more of the sun’s heat is captured. Mean Arctic temperatures in recent years have been as much as 3°C above their long-term averages.
