Mrs Rinehart points out that some people received notoriety claiming only a few decades ago that the earth was about to enter an ice age and understands some of those same people are now claiming, global warming instead. Mrs Rinehart admires people like Ian Plimer who have independently chosen on their own accord to stand up against this tidal wave, which has caused fear, and despite substantial attacks by some of the media and extremists for so doing. It is noted Professor Plimer had his own views on climate change long before he knew Mrs Rinehart and had given many such informative speaking tours prior to meeting Mrs Rinehart.
