It’s silly because you are making the argument that “Because something caused “A” to happen in the past, every time “A” happens is for the same reason.”
The earth has been much warmer than it is now, and it has been much colder. The atmosphere didn’t use to be 21% oxygen. Enormous volcanoes have erupted, asteroids have hit the earth, various sun cycles, etc., and they have all had enormous impacts on the earth’s climate. But that doesn’t mean *other* things *can’t* impact it. It’s a really complex system with about a million feedback mechanisms.
Besides, you wouldn’t say “Earlier today it was light in my room because the sun was out. Therefore, whenever it is light in my room, that means the sun causes it.” It’s just bad logic.
Climate.
Complex it is.
What did Michael Crichton call it?.. a “non-linear coupled chaotic system not subject to modeling”...?
