I don't think you can compare prof. Ian Pilmer with Farrage or Johnson Tommo!
I believe he makes a lot of sense. Whilst I'm an avid protester against using depletable resources (coal, oil, gas etc.), I'm an enviromentalist and conservationist, I also happen to think that the man-made climate change scare IS a scam. Climate change is here, has been here and will continue to be here for as long as the earth is in existence. What infuriates me is the 'Chicken Licken' mentality that has been generated and propagated by the elites. The poor guy in the street, who believes all this nonsense is quaking in his boots. At the root of it is the evil called money, plain & simple. It's the guy quaking in his boots that has to dip in his pocket to pay for the scam, tax money for 'renewables' subsidies (carbon tax etc.). As usual, the tool used to get what the elites want is fear, fear of terrorism, fear of global warming and it's effects, fear of nuclear war, and it goes on. A fearful population is a malleable one, who allows those in power to take away all their basic rights and freedoms.
As for the 'Greens', well meaning as many of them are, they are very deluded and sadly just as manipulated through fear as the rest of the population, without realising it. They are dancing to the fiddle of the elites - without even seeing it!
