As Climate Vigils and Days of Action took place around the globe, no place was more exuberant and lively as Copenhagen, Denmark.

With 100,000 climate supporters marching in the streets, the home of COP15 is also now home to the largest climate demonstration in history! I'll note that Australia was a close second, with 90,000 citizens marching in the blazing summer heat.  Amazing!

I unfortunately missed out on the action, as I have been bedridden with the flu for the past 3 days.  I have still been contributing where I can over email, and sharing in the joy as media hits from the UK Guardian, New York Times, and other major newspapers roll in showing video footage and photos of my friends from the US Youth Delegation out in full swing.

The picture above was taken from a cell phone camera and tweeted across the globe.  As this diverse crowd of 100,000 marchers flowed through the streets towards the Bella Center, where the climate talks are being held, Nobel Laureate Desmond Tutu held a vigil inside.  Tutu declared that the vigils are intended to ''inspire world leaders to remember the generations that will inherit a world forever shaped by the consequences of climate change.''

From the air, Copenhagen is a sea of light from the candles that visually represent the hopes of the more than 11 million people that told world leaders that they are ready for a fair, ambitious, and binding climate treaty in Copenhagen.

The crowd was incredibly diverse as it was made up of both Danish supporters of climate action and the unprecedented number of civil society representatives from thousands of organizations that have come from all parts of the world for the United Nations climate negotiations.  Civil society leaders and young people from developed and developing countries came together to ask their leaders to definitively action on climate change.
