How much more time should we devote to preventing global warming before we start thinking contingency plan?
Inspired by the 20th anniversary climate conference in Rio it occurs to me that in twenty years of talking nothing much has happened in the way of preventative measures regarding CO2 emissions and perhaps it's time to start thinking about coping with climate change as I can't see the next twenty years being much different to the last regarding global action. What action needs to be taken? Should we start moving people from low lying areas before it becomes necessary? Should we start thinking about where our farms are and where they might need to go?
