but that has little or no proof, merely conjecture and postulate

even if humanity was responsible for some of the warming, in the end it will make little difference

if we are in a warming stage, it will get warmer; if it is just a short term blip, then the climate may get cooler. Either way, nobody will be around to make measurements
