Why is global warming a bad thing?

Tommy,

I wonder about just what we can accomplish with all we are going to spend and give up. We can't stop the climate changes as the Earth has a long history of them. Some take thousands of years and others in the hundreds of years, so what we put in the air probably is speeding up a normal warming cycle by some years, but no one knows how many, and it may even slow down the cooling cycle that will follow. I watch and read all I can about it and they were showing rocks in Manhattan that were gouged by the last ice age that covered there and it wasn't that long ago in the time frame of the universe. I would like to see some of the junk out of the air for health reasons more than the climate change as I doubt if even I will be around in another 70 to 150 years when they say it will reach the warmest point. It would be interesting and as one of you mentined a rapid warming would really devastate some of the coastal areas. Some scientists want to focus on getting people away from what will be covered in water and making arrangements for a new way of farming and raising food because much of the land now used will be under water. To me that makes more sense than trying to stop what is going to happen.
