Eric,

Some folks may exagerate or offer worst case scenarios as fact, but it is a fact that our human race burns 6-7 gigatons of fossil carbon per year and that CO2 concentration has increased 30+% since 1850. The World is very big but we little humans are changing the atmosphere.

The extra CO2 reduces net IR radiative losses (particularly ~15 micron IR) from the Sun warmed Earth surface to the 3 degree K of outer space until a new higher surface eqilibrium temperature is achieved.

Here are a couple websites to debunk most of the typical skeptic talking points:
