Climate Change

I'm still wondering how they KNOW what the CO2 levels were 3,000,000 years ago. "Know" being the key word

And how did that happen without humans burning fossil fuels. And why did it get better. And what are all the other myriad and unknown parameters that caused it all, and are those the same parameters that exist today. And could it all revert back to those conditions after millions of years of changes in the planet and the solar system and the universe.

Actually, they don't "Know", they are guessing. Here's the study that they based the articles on.They are using computer simulations to come up with what they think has happened over time.

They haven't perfected computer simulations that can acurately predict the track of a hurricane or the amount of snowfall we are going to get. But we are supposed to believe that they can acurately predict air quality befor man roamed the earth.

Problem with some people (not you) is is that they lack the the abilty to understand basic english...or sarcasm. And they think they are smarter than they actually are.
