I think we're definitely affecting it. The temperature is getting warmer consistently, maybe not in a steady climb & maybe not in your specific community. To say humans don't affect the climate is absurd, especially considering the amount of fumes most of your toys & trucks (and all the factories that build them) put out. But I'm also not a doomsdayer. We have had some extreme ice ages & carbon ages through the aeons. I don't know that I want to live through a carbon or Ice age myself, but it can be done. (Technically speaking, we're still in the tail end of an ice age now - something they don't seem to mention in the debate). Humans have increased the rate of fluctutation.
That being said, I think if we use our brains & a free market system free of subsidies, we can reduce the rate of fluctuation & "Climate Change" or "Global Warming." GM in the early 90's created a prototype car that got 100 mpg. Not a hybrid, not an electric. Just a good-old combustion engine. I read about it in Popular science as a teenager. So... What happened to it? Pretty sure Big Oil squashed it. Pretty sure Big Oil was behind Trump squashing Obama's standards he put up too. I'm not really all that in favor of the government saying "you must get your fleet to such & such MPG," but what does a little incentive hurt? Ultimately, people will vote with their pocket books, if given the opportunity. I'd love to have a powerful electric vehicle that I can plug in to affordable solar panels to charge. Not so much because I'm a tree hugging guy, but because I think if you can use the sun to power something, that's about as cheap as you can get, with as little interference from Big Brother as you can get. And thanks to guys like Elon Musk, I think its on its way. And that is how things get fixed right. Not from the top down.
