Global Warming

Yahoo! News - Ocean, Arctic Studies Show Global Warming Is Real: "Ocean Conveyer Belt "

There was a good show on PBS the other night that detailed the facts about the Thermohaline conveyor. ( http://seis.natsci.csulb.edu/rbehl/ConvBelt.htm ) Alan Alda was the narrator and he always does a good job of making the dull facts into interesting facts. If you look at the map from the CSULB page, you can see that Greenland is right next to that point in the ocean where the conveyor dives down and then travels south. If you mix in a large amount of fresh water (melting ice cap) the fresh water won't sink and the conveyor stops.

This happened once before in recent history. The "Little Ice-Age" affected millions of people in Europe and it wasn't until the late 1800's that the cold began to abate.

It is probably too late to do much about the current causes for global warming, but it is irritating that some people still think it's a hoax, cooked up by "tree huggers". I hope those people have parkas...
