It wasnt that many years ago we were claiming a new Ice age was on the way.....I remeber those "findings" in school. We have come full circle and I think its safe to say there is no certainty to anything at this point and level of understanding of our earth other than death and taxes.
I think you have the logic behind the importance of atmospheric CO2 as an agent to alter the earth's albedo out of context. If the CO2 concentration was that of Nitrogen, forgetting the fact that that is not possible for a second, small changes in the amount of CO2, on the order of a hundred ppm over a century, would be relatively meaningless. However, at a pre-industrial level estimated by scientists to have been around 280 ppm (http://news.bbc.co.uk/1/hi/sci/tech/4803460.stm
and I know you will discount it as it is a BBC reference, but ignore that for the moment), and its apparent strong influence on the earth's albedo, even at such a low concentration, the increase to 383 ppm by March of 2006, is potentially significant. If we were to stop the rate of increasing our CO2 emissions, it is very likely the earth's climate control systems would get busy and stash much of the extra CO2 deep in the oceans, in polar ice caps and what ever other mechanisms exist, and the concentration would slowly return to some equilibrium point without any other disturbing influences.
Unfortunately it seems the CO2 stashing mechanisms have been upset enough that now, former CO2 stashes (polar ice caps, for example, and the slow warming of the oceans which will release dissolved gasses of all kinds) are being emptied into the atmosphere as well. That is a bad omen, as any corrective action humans may take will have to neutralize and then reverse the loss of these CO2 hiding places.
If you recall, earthquakes and in some instances, mining operations, can stir water from deep lakes or the oceans and bring this water to the surface. The result is like opening a bottle of shaken cola/carbonated pop at body temperature. The water appears to boil as the gasses in solution at the ambient pressures at the depths of the water has come from, comes out of solution at atmospheric pressures. Typically there is very little O2 in this mix, and whole villages, or mining operations, have been wiped out by the sudden displacement of oxygen.
No one is assigning "blame" for global warming. We are doing nothing more than identifying the only player in this game we can control - which is the human player. The human contribution can be quantified and controlled, if we try. If we merely decide, as a species, that this is a problem for someone else to worry about, we will, as a species, face the consequences.
The evidence for the human player's influence is presently remarkably well tied to the success of humans as a species to populate the planet. The correlation is statistically nearly obvious. It was not apparent earlier because no one was looking. Now that we have observed and are tracking the correlation, it is very difficult to ignore without some motive to ignore it. As I said earlier, it is not "normal" to worry about future problems when faced with immediate ones, like eating or finding shelter, or, in our new industrialized world where those issues are less prominent, things like getting a hair cut or impressing our neighbor with our new, bigger, shinier and more expensive car. The message is, lets not let global warming get in the way of finding and securing food and shelter, or personal grooming and sanitation. But lets consider it when the choices can be easier, meaning they have no detrimental effect on the actual quality of our life. Eventually maybe we can learn to distinguish between icons we worship that project a higher quality of life, and actual quality of life.
The longer we wait to take any action, the greater the challenge to humans to control the releases we are contributing to becomes. It is entirely plausible that the problem could become uncontrollable if we wait long enough. But it will be very apparent, as it interferes with our ability to secure food and shelter on a daily basis.
