Irrefutable?
If you want proof of something take a math class
What would math have do with the causes? - nothing
If one can't define "irrefutably" the cause of something - then what money sum would you be willing to spend?
I can irrefutably proof to you that Africans are in civilization/cultural terms far more backward then Asians or Europeans. So how much money do you want to spend to change that?
And on what?
Just education?
Taking over their governments?
Special programs to get them out of their tribal mindset?
Teaching them why people should not eat with their hands, how toilets are to be constructed and maintained?
Teaching them that Slash-and-burn agriculture isn't a great idea?
How to set up rudimentary windmills that can pump groundwater - instead of waiting for the water truck?
How to get roads done without - foreign or UNICEF aid, paying for road construction machines?
Or don't do anything because some people say that Africans are genetically born dumber?
You propagate Nuclear power - which as I had mentioned many times, would have logically reduced the CO2 output via industrial plants and households. So tell me what % impact does the Man-made CO2 output have on the overall CO2 measurement? - if you don't know "irrefutably" - then why would you propagate spending trillions on nuclear power-plants? because math tells you that, or your neighbor?
You obviously refute the existence of Climate change - therefore you start a dumb and meaningless thread - to please your own ignorance and that of your ignorant followers.
