You global warming deniers do understand that oil and coal are stored forms of carbon. In a liquid and a solid respectively.
Man turns them into a gas by burning them. And puts them back into the atmosphere. How could that not have an effect. And a negative one at that.
I bet you all think God opens a giant chimney up in heaven and lets all those bad gasese out. Is that what you all believe?
The question is not whether pollution has an effect on our environment. The question is how much effect it has on our climate. If you suspect that it does increase global warming, then the second question has to be whether that increased global warming will be beneficial or harmful to life on this planet. Currently, we don't know the answer to either question.
The third and final question is, if our pollution is causing the earth to warm faster than normal, and if this will be detrimental to life, is there any thing we can do to remedy the situation? The answer to that one is no.
You seem reasonable.
As to the person stating that the last time CO2 levels were this high in the atmosphere, vulcanos were going crazy spewing noxious gases all through the atmosphere.......and the earth survived.
Well ain't that just great. Were we trying to grow soybeans, corn, rice and cows at the same time to feed ......how many billions of people now?
You all don't get it. All it takes is to screw the weather patterns up just enough that our crops are not able to grow to full yeilds. Maybe a cold snap in May when all the fruit trees are in full bloom. Maybe a drought that goes on for years in the middle of the country. Oh wait, that's already going on and, yes droughts have hit the middle of the country before.
But sea levels are rising around the world, crop lands are going under water,
You know what? Somehow, through God or Good Luck, the world evolved into a well balanced, orderly system. We had plants that depended on CO2 to grow (which us mammals happily supplied) and we had animal life that needed Oxygen to grow, (which the plants happily supplied.) We have a carbon based life system and we had an abundance of carbon stored in oil and coal. We had balance.
Now we have severly depleted the earths ability to handle the amount of carbon we generate. A huge carbon trap exists in the form of the rain forests. Which we proudly watch as they are cut down to raise cattle for cheap hamburger. You can't cut down the greenery, burn up the carbon deposits and not expect the system to become out of balance.
A huge heat trap exists in the oceans and the water is warming. Releasing more heat into the atmosphere.
We have crops that have come to depend on growing and producing within a certain time frame and certain temperture ranges. Screw all that up, by changing the weather patterns and our food producing ability takes a big hit.
We don't kNow what burning billions and billions of tons of oil and gas will do to the world BECAUSE IT HAS NEVER BEEN DONE BEFORE.
But it (burning oil and coal) represents a lot of released energy over time and something has to change.
We do know the last time carbon levels were this high. Big vulcanos and big animals. And I don't think we would have found the earth to have been a very friendly place for us humans.
Of course if you believe the Creationist Museum in KY, we could walk with the dinasors again??
