Thanks much fellas, very helpful explanations all around. Much appreciated!

Hey guys, I have a question that's been bothering me lately and I'm hoping someone can give me the scientific explanation. Everything is made up of atoms.. myself, the table in front of me, etc.. correct? And atoms are pretty much just empty space right? (I seem to remember an analogy along the lines of "if the nucleus is a basketball in New York, then the electron would be a golf ball in London".. or something to that effect). So it stands to reason that my body and everything around me is pretty much entirely empty space right? If this is the case, how is it that I can see and feel these objects? What am I seeing and feeling? Thanks so much in advance.

Supposedly there is a debate over global warming... debates have two sides. I'm just trying to get some idea of what the skeptics are saying (and whether any of their arguements have any validity, or if it's just a case of not understanding the subject that they're criticizing). I'd appreciate some help from those of you who follow this subject closely!

Are there any good arguements against the theory of global warming? I've heard things along the lines of "we're currently coming out of an ice age and the earth would be warming naturally anyway", "there is warming in some regions, not in others", "we only have records of temperatures over the past century from the USA and some parts of Europe", ...and perhaps some others I can't remember. ..are any of these arguements reasonable? Are there any other evidence/arguements contradicting the theory of warming?
