If one had to explain climate change, one can easily use the feedback loop mechanism by saying that the world's atmosphere is changing from a negative feedback loop(self-regulating cycle) to a positive feedback loop(self-reinforcing cycle).
A good collection and explanation on feedback loop is here: http://www.wired.com/magazine/2011/06/ff_feedbackloop/all/1
So, what's the consequence? According to Wikipedia, "Positive feedback tends to cause system instability. When there is more positive feedback than there are stabilizing tendencies, there will usually be exponential growth of any oscillations or divergences from equilibrium. System parameters will typically accelerate towards extreme values, which may damage or destroy the system, or may end with the system 'latched' into a new stable state."
In the past, similar trend had lead to ice age and it can happen again if the current state of affair continues!
