The point is, this is no more far-fetched or ridiculous than the bogus, trumped-up global warming theories that abound today. Why was it so much warmer 1000 years ago than it is today? There were no SUVS or farting dinosaurs then.
The earth is or isn't warming because that is just what the earth does.
No, bull****. Fox News is making up something ridiculous
and attributing it to scientists. It's not comparable at all. AGW theory has a lot of evidence and research behind it. "Dinosaur farts caused their extinction" is entirely a fabrication of a single Fox News tech writer. It's a lie, straight up, and here you are trying to defend being lied to.
Why was it warmer 1000 years ago than today? Well, first of all,
it wasn't. People give you that idea by showing you a temperature chart with a prominent hump labeled "medieval warm period." There was a medieval warm period, but
globally it wasn't as pronounced as that chart would make you think. Current global average temperatures are higher than the global average back then. The graph they showed you was a
regional temperature reconstruction.
Next, are you under the impression that AGW theory indicates that
only humans can affect climate? That
only CO2 causes temperature changes? Because that's idiotic. There are numerous variables involved, all of which get extensive research. To make this statement of yours means you're either ignorant of those other variables or you are deliberately ignoring their discussion.
"Just what the Earth does." What, like it's magic? Magic makes the Earth change temperature? Or would you say that, perhaps, there is a measurable physical mechanism for those temperature changes? If so, what makes you think this hasn't occurred to climatologists?
Why would there even be a field of paleoclimatology if scientists thought
only SUVs caused temperature changes? When something in a scientific field you have no knowledge of sounds ridiculous, you should consider the possibility that you don't properly grasp what they're trying to explain to you.
