Eh, "Global Warming" is fine. Texas isn't the globe. I've come to believe the whole "If we explain it differently, maybe it'll convince them" approach is largely a waste of energy.
Excuse me, but as a resident of the planet Texas, you both are wrong in assuming we have the ability to comprehend anything we didn't hear come from our own assholes.
Climate change is a GOP/Oil industry invented term to sound less scary than global warming. It doesn't mean no snow ever again, or every square inch of planet is warmer than last year.
I don't object to that term. With "climate change" we get the opinion "well climate has always been changing so drill baby drill won't make it stop changing".
