does your environment's temperature affect metabolism?

My question is having to deal with temperature and your metabolism. I am pretty sure that if your environment were really cold, your metabolism would speed up because it has to generate heat to keep your body warm. However, if the temperature is very hot and you are sweating a little bit, what effect does this have on your metabolism?

I ask this because I am back in college and this time there is no air conditioning - it is very hot, and it seems like I am always hungry as hell even though I am eating enough.

I think you have it backwards, the hotter the air around you gets, the higher your metab. will go, i.e. sweating.
Very cold temperature slows metab, which is why you hear occasional stories of a person who falls through ice, is under for half an hour and lives to tell about it with no adverse effect, maybe some frost bite. I would think there is an optimum range, more isn't always better.

i also thought that being cold burns more calories as your body has to work harder to keep warm. could be totally wrong, no idea.

Anyone else? If this topic were in Training people would be all over it, but it doesn't really pertain to it so..

According to my biology teacher that was very knowledgable, the body's metabolism speeds up in the winter to stay warm and slows down in the summer to stay cooler. I don't now how much of a change occurs though.

Metabolism isn't body temperature it is when food is broken down for energy. During the process of breaking down food your body creates heat. The heat outside your body is an outside factor that will elevate your body temperature and that is why you sweat. But sweat has no role in breaking down food it is simply to cools your body down.

Well,
Iam not a doctor, but that makes sense. But how did that kid who was underwater for 45 min have no brain damage and walk away with just frost bite?

Hotter=faster, colder=slower, your body may be working to make extra heat, but, its still slowed by the actual chill
