Climate Change – we must act.

Hot on the heels of Nicholas Stern’s lectures at the University of Auckland comes Greg Craven a high school science teacher who posted a ten-minute video, The Most Terrifying Video You’ll Ever See, predicting dire consequences without strong measures to stop global warming. That video attracted millions of viewers; his focus now is not “what” to think about global warming, but “how.” Using clear language and charts, Craven sketches not just the cost/benefit analysis of over-reacting and failing to act, but the fundamentals of sound science. Well worth a look
