If you think Trump is that smart then I've got a $400 campaign hat to sell you.  All fluid systems are inherently chaotic and thus difficult to model.  Yet, somehow, we can forecast weather quite accurately most of the time.  (Harvey's torrential rains were nailed 48 hrs out, for instance). Climate is inherently more difficult to model due to the longer time frames, so you just dismiss those models are worthless.  Yet, climate models have been correct or, more recently, a bit too conservative with regards to the changes we are seeing worldwide.  The entire polar amplification has long been predicted and we've seen that in spades, for instance.
The goal is not to redistribute global wealth - you misrepresent the issue for political gain - the goal is to save the earth, the most noble of cause of all.  Your willful ignorance only hinders our efforts.  Why you'd sacrifice the habitability of our biosphere for political gain is beyond me.
