I agree with him on many points – green tech is great, cleaning up the planet is a fantastic idea, but carbon credits? Bad idea
My study is NOT as a climatologist, but from a completely different prospective in which I am an expert.
Complex data from disparate sources can be processed and presented in very different ways, and to “prove” many different theories.
For decades, as a professional experimental test engineer, I have analyzed experimental data and watched others massage and present data. I became a cynic; My conclusion – “if someone is aggressively selling a technical product who’s merits are dependent on complex experimental data, he is likely lying”. That is true whether the product is an airplane or a Carbon Credit.
