Yea, last time I checked the entire earth was covered in ice and guess what? It thawed out and that was waaaaaayyyyyy before any man made greenhouse gases were around. Just look back when we were breaking heat records a couple weeks ago. Did you notice that some of the records were several decades old? Whats up with that? Look, the world is changing, it always is. Remember the dinosaurs, well they're not around anymore, and we didn't get rid of them. Everything in nature runs in cycles. Don't know where ya'll hunt but it gets down in the low 20's quite a few times, even the teens. Hell just a few years ago we broke a record for cold days in single digits. Nothing ever stays the same.
