Australia

I've just come off the phone after talking to my son in Oz. He's touring with his girlfriend and her parents and they are now in Alice Springs.
Poor Australia will be hit very hard due to global warming. At least there is not a huge population to worry about. The effects have already began. Bush fires and floods are the first sign. In a few years most of the island continent will be uninhabitable.
I guess most of the population will ultimately gravitate to the South Coast or even New Zealand.

Its good that my son is there now though, he'll be able to look back on it and tell his grandchildren what it used to be like.
