Of course not! One scientist you have a theory. Two scientists and you have confusion!

Terri,
I wonder if you meant to say the 'effects' of carbon dioxide (CO2). I don't think there's any dispute as to what causes CO2.
It's pretty much unanimously accepted within the scientific community that emissions of CO2 and the other 'greenhouse' gases contribute to global warming through the greenhouse effect.
Where there's much debate and disagreement is in relation to the extent to which these emissions contribute to global warming. There are predictions from eminent scientists and respected 'think-tanks' that estimate the earth's temperature will rise anywhere between 1 and 7 degrees in the next century and that greenhouse gases could be just one of many factors or could be the predominant factor.
The earth naturally goes through warm and cold periods and there's no preset pattern to this. This is the big unknown factor - just how much of the rise in the earth's temperature is natural and how much is man-made.
It's often difficult to get impartial information about the greenhouse effect as both sides have vested interests and tend to exaggerate and distort the truth. One good and impartial site is the BBC which has more info here...

No, some scientist believe the excessive carbon dioxide in our atmosphere is contribuitng to global warning, others believe global warning is just a part of the earths tempreature changes just like the ice age thousands of years ago and will bypass after time.
Hope this helps
