No-one thinks coal is good for the environment. So, why is a coal-heavy, national mining forum about to be held in Dunedin? Bruce Munro takes a look.
Children are going on strike over their health and wellbeing while schools are still burning coal, writes Alex Macmillan.
An information night at Knox Church's Stuart Hall at the weekend, to discuss the Schools Strike 4 Climate rally in the Octagon on March 15, was a "great success", Zak Rudin (16) said yesterday.
New Zealand should join the global effort to mitigate climate change. It's the rational decision, writes Elisabeth Ellis.
Sustained levels of moderate warming could melt the East Antarctic Ice Sheet, possibly contributing to up to 19m of sea level rise, researchers, including one from Otago University, say.
Melting ice caps, floods, droughts . . . concerned? As the clock ticks down on the Government's Zero Carbon Bill consultation, now's the time to let them know, writes Tom McKinlay.
