You might find it interesting to read about the evolution of our atmosphere and how significant changes occurred over hundreds of millions of years. Photosynthesis being a major player. Photosynthesis that consumes co2 and releases o2 caused the first mass extinction on earth, killing most anaerobic life. Then the increase in o2 caused the world to freeze when it reacted with the abundance of methane to produce a greater ratio of less greenhouse effect co2. Then with ever increaseing o2 in the air the earths minerals reacted and oxidized. With time a balance was formed and more advanced life was able to evolve. Nevertheless, the earth still went through periods of freezing and warmth. The scale of all this is huge beyond our understanding. Check out snowball earth on wiki or the great oxygenation for details.
I agree with you, that was a nice explanation. It is crazy how long it takes for the earth to go in and out of these cycles, and it's difficult to explain with 100% accuracy considering no one during those times knew science or could live long enough during them to document how it happened. I took a Weather and Climate science class in college, and I learned quite a bit about weather patterns and the way climate works, it was very interesting. I made an A in the class and while I didn't study science as my major, it has always been my best subject in school.
It was a very interesting class for me.
I've had so many debates with my ex roommate who is a huge conspiritor. He watches one film on YouTube about how the universe is 1 giant computer simulation, and all the sudden it must be true!!
the dude says 1 giant computer simulation in a British accent so many times you almost start to believe it. Omg it was so funny I still crack up to this day thinking about it.
