It remains to be seen exactly how useful Kyoto is in reducing greenhouse gas emissions, but it is a start. Likewise, it is another example of international cooperation, and climate change doesn't know about our socio-political boundaries.
New Zealand are signatories, and to my shame, Australia is not. So it is with some amusement that I note that an NZ speaker at a climate meeting in Adelaide recently noted that with climate change, we will need to buy more food from them. Australia is becoming increasingly arid (and the increasing frequency of the El Nino Southern Oscillation is not helping). However, strengthening westerlies may bring more rainfall to western NZ, increasing their growing season (though resulting in drier conditions due to the Foehn effect on the eastern side). Reap as you sew perhaps?
