Climate change is a naturally occurring phenomenon, not caused by human activity

Man, I get so frustrated when people claim climate change isn't caused by human activity! Like, come on, have you seen the pollution in my city? It's not all natural, trust me. We need to take responsibility for our impact and make some changes before it's too late.

I get that the climate has changed naturally over the years, but come on, you can't ignore the impact we as humans are having! Just look at how much we're pumping into the atmosphere - it's not rocket science, it's common sense. I mean, I've seen the changes in my own neighborhood, and it's not looking good. Let's own up to our part in this and start making some changes.
