My position on climate change is that greenhouse gas emissions beyond doubt cause warming. There is a legitimate debate about how much warming will occur, as we do not know for sure how the rest of the very complex climatic system will respond.
But personally I don’t find Monckton a particularly useful contributor to the debate. He has a history of over-egging his claims and this rebuttal by John Abraham shows that he has quoted people out of context.
I think the biggest challenge with climate change is getting the major emitters to agree. An agreement without China, India and the US is basically worthless in environmental terms. China’s daily increase in emissions is greater than NZ’s total emissions.
