I have stopped trying to argue with someone who refuses to look at anything but that which supports his own position. It’s pointless. So in an effort to end a debate quickly, I now politely ask individuals to explain how CO2, given how small it is relative to all around it, actually changes the entire system. That usually stops it with most of the crowd. Like many things I see with new age forecasters today, they will jump on one weather factor and not understand its behavior is because of everything around it.
