But … how do you know? Because some people who are really smart and who work really, really hard on this topic (we call them "climate scientists") have done the work and are pretty confident of their results. Plus it's already starting to happen. Let’s face it, your truth is based on faith No it's not. If you want to, do some reading on the subject. It's pretty easy to find good stuff to read, actually. Or if you want to just keep reading stuff that confirms what you want to believe, that's fine, too. I really don't care. Climate models and predictions have been famously less than accurate. We can't predict with perfect accuracy, of course. But we can predict with a pretty high degree of assurance -- just like you can predict the arrival of an oncoming truck, once it gets close enough. And when it approaches within a certain distance, and is moving fast enough - you better damn sure get out of the way. In terms of climate change, we are already at that point.
