Speaking as someone educated in Maths at the windy and cold cloisters of Cambridge University, some 30 years ago, I was long ago educated in the concept of the word "axiomatic" This in English means "self-evident" or "obvious", but in Mathematical terms means an assertion that is assumed to be true upon which we can base all our other assumptions or theorems. It seems to me that we need to determine what are the axioms of climate science. From my relatively short time delving into this topic (h/t to WUWT) with all its emotional and political baggage, we desperately need to return to first principles and determine "what are the axioms of climate science?" (Specifically with respect to climate change or global warming) Is it axiomatic that the earth is currently warming? Is it axiomatic that CO2 is a greenhouse gas? Is it axiomatic that mankind is emitting CO2? These are some of my questions and I have learnt to completely throw out all my pre-conceived ideas and start from scratch. Any ideas?
