One Possible Reason Sunscreen Doesn't Sell At The South Pole

Scientists have discovered that the exhaust plume from space shuttle launches can eventually lead to an increase of cloud cover over Antartica. To a certain extent this can be expected, since the shuttle burns liquid hydrogen and liquid oxygen. What was surprising, however, that this water vapor can eventually make its way that far south.

These findings carry important ramifications for the study of global warming, some of which is based on evaluating cloud cover over the poles.

Now I like to think I'm as environmentally conscious as the next Bush basher, but quite frankly I find it hard to be concerned about this. Who cares whether or not penguins can work on their tans? There are much more important things to worry about when it comes to the shuttle program.... Like if I'm going to get hit in the head by a piece of it on the way down.
