Dr James Hansen is a professor in the Department of Earth and Environmental Sciences at Columbia University. Some of his quotes:
it is very bad to the earth,humans,and plants..
scientist are trying to find out ways to prevent it.
well there are a lot of reasons that we cause golbal warming. The main one I can think of is every time that you plug something in. I believe that global warming is not being caused by humans. There are just as many scientist saying that it is not happening than there are saying that it is.
well scientist knew about it 30 years before but however did not have any evidence on there are many sceptics now a days how still don't believe global warming is man made!

Climate change. Though that is actually caused by global warming.

No. Although Al Gore himself is not a scientist, he has listened carefully to what scientists have to say about global warming. He is concerned about scientific predictions about the potential effects of global warming on society and the world as a whole, because that is what most scientists are telling him.
The science of global warming could be a scam if someone had anything to gain by it. Yet scientists resisted the idea that they should be concerned about the possibility for almost a century after the possibility of anthropogenic global warming was first identified. No scientist has anything to gain by creating a hoax. In fact, any evidence that a research scientist has engaged in a scam would be career-destroying.

Global Warming.
by creating simulation models
global warming!!!!!!
global warming has started because of population of the o-zone layer are our world and many scientist think that the world might end IN 2012 "population of the o-zone layer" and "many scientist think that the world might end in 2012" Come on what kind of gobbledygook is that? Globan warming and global cooling are natural cycles caused by sunspot activity and other natural factors.
