You do realise it is possible to just start with the basics and find real world evidence?
For example, when I have visited a particular glacier three times over the past 25 years and taken photos of it, I have real world evidence of it getting much bigger which indicates the temperature is cooling.
And when I see "news" reports saying that the very same glacier is melting, but they are reversing the order of their photos, that is evidence of another kind.
And when people avoid refuting any statements I make by talking in circles around the subjects, that is revealing a lot as well
