Patrick Moore, co-founder and leader of Greenpeace for 15 years, is now an independent ecologist and environmentalist based in Vancouver, Canada.  In an opinion piece, published in The Australian of 24 November 2014, he discusses the influences of the climate debate on Australian politics and the impacts of changes in the level of atmospheric carbon dioxide through time on biodiversity.

Moore is sceptical regarding the proposition that humans are the main cause of climate change, and that it will be catastrophic in the near future. “There is no scientific proof of this hypothesis, yet we are told “the debate is over”, the “science is settled”.” he states in the article.  He expresses skepticism regarding assertions that “the global climate with a computer model. The entire basis for the doomsday climate change scenario is the hypothesis that increased CO2 due to fossil fuel emissions will heat the Earth to unlivable temperatures”.

He also discussed the claim that “CO2 is a “toxic” “pollutant” that must be curtailed when in fact it is a colourless, odourless, tasteless, gas present at 400 parts per million of the global atmosphere and the most important food for life on earth” and proposes that “without CO2 above 150 parts per million, all plants would die”.
