Eminent professor of geology, Ian Plimer, writes in 'The Austraian" newspaper: As soon as the words carbon footprint, emissions, pollution, and decarbonisation, climate emergency, extreme weather, unprecedented and extinction are used, I know I am being conned by ignorant activists, populist scaremongering, vote-chasing politicians and rent seekers. Pollution by plastics, sulphur and nitrogen gases, particulates and chemicals occurs in developing countries. That’s real pollution. The major pollution in advanced economies is the polluting of minds about the role of carbon dioxide. There are no carbon emissions. If there were, we could not see because most carbon is black. Such terms are deliberately misleading, as are many claims."
