Adrian Macey: Climate scientist says even if NZ's emissions hit zero tomorrow, it would make no difference

It's thought anything this country does on climate change will have no impact until the whole world responds. A 1News Kantar Public survey reveals more than half of respondents want the Government to act with more urgency on climate change. The poll, taken in reaction to Cyclone Gabrielle, finds 27 percent want officials to continue as planned and 10 percent want less urgency. But Victoria University climate scientist Adrian Macey says even if the nation's emissions hit zero tomorrow, it would make no difference. He says the climate we experience is entirely determined by what big countries like China, Russia, India, the US and Brazil do with their emissions.
