What would happens when global warming gets really bad?

It will start by melting the ice caps (already happening) which in turn would raise water levels all over the world. The weather patterns would change and there would be more major storms. This I know can happen. What I think will happen from there, please understand this is my opinion and not a fact, there will be a lot of moisture in the air, and this will cause a lot of cloud cover. The clouds can block the sunlight, making the planet colder, and possible creating another ice age. I don't know if that makes a lot of sense to you, but it gives us something to think about. Every little thing we can do to stop global warming would be a good thing, no matter the outcome.

I really don't pay much attention to Global Warming, I belive what God has told me in the bible about the earth and what is going to happen. I think that it's probally the last thing that will ever worry me.

ofcourse it will. It would cause extreme weather conditions. Big hurricanes, typoons and heat waves. We could eventually die if global warming gets worse.
