RE:Climate changeDuster, All that I know for sure, after having made my living applying thermodynamic principles, is that if the air temperature is getting hotter, then for a given pressure, the water vapor in it will be less likely to condense into micro-droplets aka clouds and less precipitation will fall to the ground. That is a scientific fact. Check out the "steam tables" in any thermodynamics 101 text book.
Also, much more H2O will change phase from solid (ice) to liquid (water) for a given pressure. The sea levels will rise. I once saw a graphic of what the US would look like with a 2 meter rise in sea levels. Much of the east coast would be under water. The Mississippi drainage basin which includes all major trbutaries like Ohio River would be flooded extending from almost to the Rockies to Pittsburg. The St. Lawrence would be a big lagoon extending into large swaths of Ontario, Quebec etc.
It's already starting to happen. They reckon that Venice, Italy might not be a viable place to live in the next generation. I'm not being alarmist. I'm just watching for trends and they seem to point to a warming global average temperature. I won't get into causes. But people had better figure it out I think and learn to become more adaptable.
