It is -8f (-22c) here and I need to take some outdoor pictures. If I went outside for a minute or two would it be dangerous for the LCD on my camera?

For a few minutes? No
Prolonged exposure (where you will actually see a drastic temp drop in the camera)? Yes.

It also depends on wind and such. If it is more windy, your camera will chill faster, and thus not used as long.

check the manual there should be a temperature guide for safe operation.. I was also out side for about 1.5 hours today taking pictures and was -20c & 30c with the wind chill, was out for some time yesterday as well in similar conditions have had no problems though I would suggest when you bring the camera indoors to leave your camera inside the bag to slowly reach room temp before taking it out to avoid condensation, thats were the damage will come from.

Actually, the main thing you need to worry about when shooting in low temperatures is condensation. The LCD is pretty resiliant. When you bring the camera inside a warm environment (like your house or car) after it's been outside for a while, condensation will form on and inside the lens and camera body. Water in lens or electronic components = bad.

There's a simple trick to avoid this, though. Find a giant Ziplock bag---big enough to hold your camera and lens inside (they sell some GIANT Ziplocks...I can fit my 20D AND 24-70L inside of a 2 gallon bag).

Place your camera inside the ziplock and seal it up when you're done shooting (but before you enter the warm environment). This will create a mini airlock of sorts. Just bring it inside and let the air in the bag equalize to the room's temperature, and you won't get any condensation on your camera or lens.[thumbup]

The plastic bag method is a winner; I've just been out quite a bit in the last couple day, lord_P, and I've used this method with no problems at all. Just be prepared to wait for a really, really long time
