Still, it's been proven that CO2 does cause the atmosphere to retain heat, but it's also been observed that globally, plant life has tended to also amp up in terms of processing that CO2 (so hey let's keep clear cutting forests, amirite? oops bad idea). There was also an era (can't remember name) where a ton of methane was released into the atmosphere from the oceans and life didn't wipe out.
When Gore talks about how cold it used to be in the 1800s at the beginning of the industrial revolution, he doesn't mention how we were coming out of a "little ice age". Also temperature recording has moved to urban centers which are subject to urban heat traps. Also the lake he shows dried up with a boat in the sand is a lake that the soviets drained.
Whether or not we actually polluting fast enough to rapidly and very harmfully raise global temperatures is still kinda up for debate, but there are other concerns related to the issue such as pollution (dirty environments and cities are bad), health issues (respiratory diseases, contaminated water, etc), ozone depletion (sup cancer etc), species preservation (various ways of ecosystem devastation is thinning/killing off species left and right), and probably others I'm missing. Not to mention greater political problems such as middle eastern oil dependence and the fact that we'll eventually run out at some point anyway.
Talk to someone in your Geography or Climatology department at your school.
