Demonstrators came out in force early Saturday morning as the sun broke through the clouds that have blanketed Copenhagen during the first week of COP15.  A huge march, with about 60,000 protesters expected, is planned for later in the day but smaller rallies are already under way as groups make their way to the main event -- the march to the Bella Center, host of the COP15 global climate conference.

Here are some video clips from one march, where protesters held aloft banners reading "Demand Climate Justice" and "Face Facts, Make Pacts". They want global leaders gathering in Copenhagen to commit to eliminating or at the very least radically reducing CO2 greenhouse gas emissions.
