Phew.. What a topic! To the OP, ZombieRus5.. Climate change is a more accurate term than "global warming". The Earth has gone through, and will go through many, many, many more cycles of warming and cooling. The geological record shows this quite readily. Our beautiful blue world has been both a frozen wasteland all the way to the equator and a boiling hellish inferno!
Did we as humans cause the current climate trends? Maybe. Are we the sole cause? Nope. Are we making them worse? Well, physics are physics, and with that.. Yes. We are making it worse. Green house gas increases temperature. Fact. The debate shouldn't be about "who did it!?" but rather.. Let's fix it. To those that say there isn't anything to fix.. I pose this statement to you.. When I was a small child, there were these things called "polar ice caps".. Yeah, 'bout that.. Have any of you seen the images of 30+ years ago verses today? Here you go, have at it denial meets reality, finds acceptance--one hopes.
At the end of the day, what does any of this mean for most of us? What can we do? The truth is, not much. No one wants to see any sort of global extinction event, but right now our hope lies in the hands of the scientists working on future energy technologies. What we can do is mitigate our impact until they can make clean energy a reality. Talking about a climate change, abundant clean energy, that would certainly change a lot of things.
I also saw someone in an earlier post mention something about scarce resources leading to WWIII? That simply will not happen. You may have forgotten, but I certainly haven't.. Far too many nuclear powers out there now for an actual world war to be a thing. It would be each of the Nuke Nations flipping the others off one final time after the first shot was fired, and an hour later.. just shadows on the walls.
I'd rather not have us end it there, humanity is far too interesting to just fade out. Let me grab my browncoat, then we got places to go, things to see. Right now it's just (not to trivialize) growing pains. We'll get through it, and over the last century we've built up a lot of momentum, so let us keep it up and moving forward.
In closing, PRO TIP: Do not attempt to change someone's mind via debate. It is futile. All anyone will do is further solidify their views, be they grounded in reality or delusion. Put the information out there and let people draw their own conclusions, because that is what they will do anyway. However, if you rather enjoy arguing with a wall.. Good for you! Here, have cookie.
