one way is computer modelling.
take, for instance, the state of the weather a few decades ago; run climate models from that starting condition which should result in as close an approximation to the current climate as possible.
If this is done just using 'natural' phenomena, there is an error at the end of the calculations.
In order to obtain a 'correct' result a fudge factor is required; that fudge is the 'missing link' attributed to "mankind's influence", when all other possibilities are discounted.
