Global warming isn't a theory, it is a sad fact. It exists whether you believe in it or not. And while the Earth has warmed up and cooled down several times over its history, from what we can tell, this one is the "fault" of humanity. I am, however, hopeful that humanity can act to slow its progress before life become unsustainable.

I have, out of curiosity, checked, living two towns in from the ocean as we do, what would happen if sea levels rose dramatically. My house would still be fine, and on dry land, but I'd need a boat to get to church, and my alma mater would be flooded, but that part is no surprise, as Boston's "Back Bay" was created from swamp in the first place.
