Global warming is real, it's not something you can believe in or not, it's not like the Easter Bunny and other shit. It's real and it goes beyond politics. Well over 90% of scientists agree that we did it and that number grows; most of the other 10% admit it too, they're just skeptical as to whether or not we caused it. But that's nearly 100% that agree SOMETHING is warming it up. The real eye opener, for me anyway, is/was the methane explosions N. of the Arctic Circle. Trapped for centuries by permafrost, that's now melting and leaving craters all over the place. Only found 'em from space, it's pretty remote, and only one thing can cause this: melting of permafrost, which by definition, isn't supposed to melt. There'a glacier not far from here that's been on camera for 100 years. Since the 60's they've had one there constantly. They can speed it all up to show the glacier receding for the last 100 years. Sure it gets bigger for a year or two and looks like maybe a comeback, but it's the overall picture we're concerned about. There are other signs too, like CO2 being elevated. This should happen on a geological time scale save large volcanic eruptions and/or asteroid/comet strikes, but it's happening on a short scale now, human time, and there usual culprits aren't here to blame.
From a mathematical viewpoint it's kind of easy to see, but if you get all your information from propagandists, I suppose it's not so clear.
The "news" channels are the last place I go to look for facts.
PS, parking lots do a LOT to help heat up the local atmosphere and that's then dispersed into the greater atmosphere.
