Earth's atmosphere?

Question

if the world back to who knows how long ago...

the planet was mainly dense forest, sorta like rainforest canopies. that means that there had to have been greenhouse gases much more than there is now. there was so much carbon dioxide in the atmosphere that caused this to happen..

we're going back to that same idea.

but how in the first place did the carbon dioxide level drop?

Answer 1

CO2 is stored in the bones of millions of animals and in the resulting rocks containing carbonates. Also, CO2 is taken in by plants and converted to various compounds like sugar, etc.

Acid rain will hit the rocks, dissolving them, and releasing CO2.

Answer 2

There is scientific fact that the earth naturally warms and cools, and the carbon dioxide levels vary too through out the years.

I think that this whole greenhouse effect/global warming is a joke.

The scientists are all saying that this currently is the warmest the earth has ever been, but i agree with you, because if you think about it the whole world was tropical and covered with rain forests and foliage back in the dinosaur age and then the earth froze and became the ice age... and now the earth is heating up again...

So in all i think believe the earth naturally warms and cools. I do not believe that humans are having effect on the climate.

Well i hope this kin of answers what you were asking.
