Ice ages have come and gone. Coral reefs have persisted.
I'm saying, Come on, the global warming thing? How did the ice melt during the ice ages? Was the dinosaurs driving SUVs around back then?
We believe the ice sheet was not around all the time. It was only around during cool snaps of the climate.
It's very clear that global climate change is occurring on earth, but it's also been very clear that that has always happened on earth. We've always had a changing climate on earth. We all know about ice ages. We know when our continent was covered with ice sheets. We know glaciers come and they go. It puzzles me that people forget that.
It's not the case that carbon dioxide drives temperatures. When you leave Ice Ages, it's the other way around: The temperatures go up first, and then carbon dioxide levels go up.
The glacier was God's great plough set at work ages ago to grind, furrow, and knead over, as it were, the surface of the earth.
You want calamities? What about the Ice Age?
The Moon stabilizes Earth's obliquity. Well, almost. The tilt actually varies between 22 and 24.5 degrees - and the variation is enough to induce such environmental inconveniences as the occasional ice age. Without the Moon, it might be much worse.
