A report by the National Academy of Sciences earlier this year maintains that global warming and climate change are now irreversible. The planet is set for serious environmental change for the foreseeable future – at least the next 1000 years. http://www.pnas.org/content/early/2009/01/28/0812721106.full.pdf+html.
What this means for communities is that it is not enough to reduce our carbon footprint – although that will help minimize future change - we must do everything we can to anticipate change, prepare for it and adapt to it. In planning terms, this means that, as much as possible, our policies and plans must anticipate and seek to forestall future disasters. The changes we need to anticipate will be both bio-physical (weather and climate, landuse, coastal morphology and so forth) and social and economic.
