From my classes, either way, the Green-House gases may not be producing a warming effect, but may be producing a cooling effect. Although many statistics have shown the warming of not only oceanic temperatures as well as land temperatures, it is still unknown whether warming or cooling will occur. Both theories have some interesting details to them, for sure. one thing, without a doubt, is a substantial CO2 rise is occurring. CO2 is generally the main emmission, since methane and other compounds are considered less dangerous to the environment. This is why when the gulf oil spill occurred, a bunch of the surface oil was burned. CO2 is considered one of the least harmful gases that is easily obtainable, but still contributes to atmospheric CO2.
The CO2 causes a barrier. Whether this will be an insulative effect and keep the heat in, or a deflective effect by deterring suns rays, nobody knows.
