I really need to get back to my work rather than get sucked into arguments with people over conspiracy theories.
Garth Paltridge's view is in a small minority. The accepted view of the CSIRO is what is published. It's not just the CSIRO, it's pretty much the same view of every relevant academic and government body that I've come across.
There is no point in arguing with someone ranting over conspiracy theories, nothing, not reason nor facts will change your view.
The science behind Climate Change and Global Warming is good, solid and peer-reviewed. Not everyone will agree with it, but it is still good science.
