As the summit moves into high-level talks, climate justice advocates are raising their voices in the streets. On Saturday, tens of thousands of people braved near freezing temperatures for a march through Copenhagen to just outside the Bella Center where the summit is taking place. Representatives from various indigenous groups led the march under banners reading “System Change, Not Climate Change.” Organizers say over 100,000 people took part. The march ended with a candlelight vigil led by the South African Archbishop Desmond Tutu.

South African Archbishop Desmond Tutu: “Well, here we are today marching and demonstrating, and the injustice of climate change will end, because climate change, the effects of it, are being felt most nearly by those who did not cause it — the poor, the vulnerable — and you are saying 'No!' to injustice. No! No!”
