There's no question that CO2 is a "greenhouse gas," meaning that it traps heat in the atmosphere. The question is whether the effect of CO2 is significant given all the other things that affect climate.
The current climate is not sacred. The earth has been both warmer and cooler in the past, and these changes had nothing to do with human activity. IOW, there are natural cycles (sun activity, ocean currents, changes in the earth's orbit, etc.) that have been affecting climate for a very long time.
I've been following this story for a very long time, and it's clear to me that the people who promote the idea of anthropogenic global warming have been ignoring some key evidence. The very fact that they try to shout down opposition -- rather than address their arguments -- shows the weakness of their position.
Fortunately, AGW skeptics are finally starting to get more media attention.
