There will never be proof. That's because this is science. Something the rest of your rant shows you simply don't understand.


What we do understand is that we have added 47% more CO2 and at the same time had a temperature rise of about 0.7 C.


Even if you attribute all the warming to CO2, which no one does, its suggests a rather low sensitivity.

And during this time we have seen crop yields increase, human life span increase, education improve, living conditions improve, many diseases almost eradicated and more people raised from poverty than ever before.

What were you saying about it being impossible to prove Co2 is dangerous? I agree, it cant be done. It can be proved CO2 is not dangerous though, its right there, in that paragraph above.
