CLIMATE FEEDBACKS
If the climateÕs response to an increase in greenhouse gases were simply to increase its temperature to compensate for the increase in greenhouse trapping of infrared radiation, the climate change problem would be quite simple.  Unfortunately, there are climate feedbacks that come into play, influencing the climateÕs response.  The main climate feedbacks are:
(1) Water vapor feedback
(2) Surface albedo feedback
(3) Cloud feedback
