As the final days of the climate talks in Copenhagen tick by, heads of state begin to arrive at the summit, and the energy in and around the Bella Center has reached an all-time high. Inside the Center, NGOs and possibly some delegates have walked out of talks. Outside, thousands of protestors marching for climate justice for developing countries are attempting to turn negotiations into a "people's assembly", chanting "Reclaim Power" --a term coined by the leaders of Climate Justice Action, a coalition of global climate justice groups. Police have arrested hundreds more today, and have even resorted to physical force, using batons and pepper spray to hold back crowds. Watch a full report on the protest scene from Democracy Now!

Accedited activists and NGOs, including Avaaz, Tck Tck Tck, and Friends of the Earth, have now been denied access to the conference center without stated cause, further inflaming protestors in the area, and resulting in a sit-in in the center lobby.

In other news, Conference of the Parties (COP 15) President Connie Hedegaard has resigned her position, to be replaced by Danish Prime Minister Lars Lokke Rasmussen, reportedly because of the unprecedented number of heads of state and government who have begun to arrive at the conference.
