  • Other scientists are specialists. They focus on a narrow topic. They do not consider the entire Earth system in their work...
  • Climate change and its impacts are here. Expect superstorms, extreme heat, high humidity, and increased spread of deadly diseases. Plants and non-human animals will die in ever-larger numbers. Civilisation will fail, leading to greatly exacerbated impacts."
  • I'm a teacher. I relay evidence. I cite science. I'm not relying on a belief system.
  • I've been accused of many things, extremist included. I'm merely connecting a few dots based on the work of other scientists. In a culture characterised by willful ignorance and the inability to think critically, these accusations are to be expected.

Quotes about[edit]

  • In many ways, McPherson is a photo-negative of the self-proclaimed “climate skeptics” who reject the conclusions of climate science. He may be advocating the opposite conclusion, but he argues his case in the same way. The skeptics often quote snippets of science that, on full examination, don’t actually support their claims, and this is McPherson’s modus operandi. The skeptics dismiss science they don’t like by saying that climate researchers lie to keep the grant money coming; McPherson dismisses inconvenient science by claiming that scientists are downplaying risks because they’re too cowardly to speak the truth and flout our corporate overlords. Both malign the IPCC as “political” and therefore not objective. And both will cite nearly any claim that supports their views, regardless of source— putting evidence-free opinions on par with scientific research.
