I'd like to say I remember NZ when it was 0.9 degrees C cooler, but I'm not that old, and I've never been to NZ. Fortunately, we have records to show me that your memories are but public displays of senility. Climate change is already affecting New Zealand. The national average temperature has risen 0.9°C over the past century. The effects that have already been measured by the National Institute of Water and Atmospheric Research (NIWA) include: fewer frosts in areas like Canterbury and Marlborough retreat of South Island glaciers – ice volume in the Southern Alps is down 11% in the past 30 years rise in sea level by 16cm – average rise over the four major ports in the past 100 years rise in insurance industry levies to cover the costs of increased incidence of extreme weather events such as floods wwf.org.nz As the water warms and sea levels rise, the increased frequency of extreme weather events is already being felt in New Zealand. Sea level rises will occur naturally, but New Zealand's low-lying areas will be vulnerable to the increased storm surges and rainfall of a warmer climate. Last week Dunedin City Council responded to the effect by annoucing new homes would have to be built 1.2 metres higher off the ground. "A 10-centimetre sea level rise increases the frequency of flooding in coastal regions by a factor of three. So a half-metre rise will increase the frequency of flooding by 300," said Naish. "We are already getting to see that in Nelson where we are getting the one-in-100-year floods happening every few years now. That's not just because of sea level rise, that is because of extreme climate change." stuff.co.nz Dunedin City Council? Now I understand why Jackson filmed Lord of da Rings down there.
