Why we need the Copenhagen conference to succeed

This delightful experimenter [2:20] illustrates how human-generated increases in carbon and other greenhouse gases are heating up the planet. Heating up the planet means climate will change. A dependable climate -- predictable weather and atmosphere -- is the set of conditions our species, and every other, depends upon to feed ourselves, shelter ourselves and keep breathing. Muck around with it, and there is bound to be trouble.

Simple enough? Can world political leaders begin to control the human component of climate stability in the meeting at Copenhagen? Our offspring will curse us if current generations fail at this.
