Yesterday and today are hosting some of the most dramatic outpouring of citizen support for international climate action that the planet has ever seen.

In Copenhagen, I watched the city streets fill with light as almost 100,000 people marched for a vigil surrounding the Bella Center, where the international climate talks are being held here.

The march and vigil capped off a a globe spanning day of over 3,000 marches, rallies, and vigils. On the 12th day of the 12th month, at the halfway point of the Copenhagen climate talks, the sun rose on rallies of tens of thousands of people in Australia and has been setting on thousands of vigils from Myanmar to the Arctic.

As the diverse crowd of 100,000 marchers held candles to represent the hopes of the more than 11 million who has called for global leadership last week, Nobel Laureate Desmond Tutu led a vigil inside. A vigil to inspire world leaders to remember the generations that will inherit a world forever shaped by the consequences of climate change.
