No, global warming is actually just a natural cycle of the Earth, it can be caused by many things, humans, not one of them. Although the alarmist love to create that illusion. However, this does not justify going out and purposely polluting in any form if you can help it. Heat from humans and whatnot is definitely not a contributing factor in that it would create such a minimal effect over the entire atmosphere.
