Human activity, as NASA and science says. So, maybe we can, as humans,, do some things differently, that is, if we believe in science. like, IDK, investing in renewable energy. There are many things we can try to do, if we believe in the science. Look, I hope those that believe it isn't real, we can't change it, it's all natural, or shouldn't change, or it's a "liberal" conspiracy, I hope they are right, the outcome of being wrong from that perspective, is that we have spent some more money doing renewable energy for example. The downside of being wrong from the perspective of science, is that, possibly, we don't exist anymore, so there's that.
Look, i'm no stranger to the right-wing majority of online car enthusiast forums, I know I'm not going to change anyone's mind here. Believe in science, or believe in Donald Trump, we all have choices.
Do more frequent, and more damaging weather events cost us anything?
