What is totally wrong?No, totally wrong.
The earth should be slowly cooling now. It's warming very quickly instead. That's how we know it's not natural, among other reasons.
What about that confoozes you so?
Fluctuations (warming and cooling) didn't routinely occurred in the northern hemisphere? Incorrect. That's exactly what ice cores from the northern hemisphere show. Can you show some evidence that shows that fluctuations (warming and cooling) didn't routinely occurred in the northern hemisphere? Because I can show you ice core data that says it did.
No. The earth shouldn't be slowly cooling now. Every 4th eccentricity cycle is nearly circular which is what the last eccentricity cycle was... nearly circular. So the orbital forcing was weak and didn't trigger a glacial cycle.
But even if it had there wouldn't have been any slow cooling. It would have been abrupt. Do you have any data that shows glacial cycles transition slowly from interglacial cycles? No. You don't. Because there isn't any. Because it's not a slow transition. It's abrupt.
The only person confused here is you. How do you like my shoes? Because I've shoved them pretty far up your ass now.
