What exactly do you think is the cause of global warming?

[Ghosty]

Global warming is caused by many things.

The first and foremost cause is that there's too much carbon dioxide in the atmosphere. There is something like 200 times as much carbon dioxide in the air as there was in the mid-1800s.

But of course, carbon dioxide doesn't just spontaneously appear.

We're taking up carbon-based things from the ground, in the form of coal and oil and wood, and burning it for fuel, putting that carbon into the atmosphere. The ocean and living trees help to put this carbon back into the ground, but not at a fast enough rate. And so globally, temperatures are rising. 2005 was the hottest year in at least the past 10,000. (Remember all the hurricanes we had then?)

Now, this doesn't mean that everywhere's going to be sunny like Florida. In fact, Europe is going to freeze, because the Gulf Stream will stop functioning. Great Britain will become more like Siberia. Meanwhile, due to the melting of the ice caps, Miami, New Orleans, New York, London, the Netherlands, and many other cities will be flooded beyond the point of livability, and the intense weather we've been having will continue to increase. More severe hurricanes, more severe droughts, more severe winters.
