If I would criticize Bush I'd use much more scathing prose. As far as I can tell, this is pretty much objective. The US is the major producer of greenhouse gases, and the current administration doesn't seem to care. Remember, this is a view from outside the US.
The wording about the signing should probably be changed, though, to make it clear that Clinton only performed the first phase. My understanding is that the normal way for this kind of thing is for the president to sign and afterward get Congress to ratify it. It's also possible for a president to get "advance ratification" of some sort from Congress, but this wasn't done in the Kyoto case. I'm sure some American can specify this in more detail (but this perhaps isn't the right place).
Please do not write on any more partisan topics, if you think this is unbiased. You really don't understand what the neutral point of view is, if you think it is unbiased. It might be "objective" if your opinions are correct, but unbiased it most certainly is not.

I can agree that much of the current text would fit under a "History" heading, but I can't say that what is here isn't factual. What is a problem as of now is that the text about Bush takes up too much space, relatively, making him look more important in this than is really the case. Feel free to change this, of course, if you don't feel like waiting for me doing it.
