to many it looks like WMD, another boogie man, or a "crisis" as whoovians might say. And making absolute statements is never good science, just blind activism.
Last I recall that nasa imaging was skewed. %97 of scientists do NOT agree on the effects (they threw out any opinions that weren't coincident with their conclusion, hmm... sounds familiar). I lived through the CFC and global
cooling threats in the 80s.
Indeed, recently nasa reported the effect of CO2 and NO in reflecting tons of heat energy from the sun, having a cooling effect:

So, please, stop pulling the fire alarm. The same properties that allow it to reflect heat back to the earth are what allow it to reject %95 of the suns heat in the first place. The climate is not as simple as one variable.
