AS close to one hundred thousand protesters have walked through the streets of Copenhagen demanding action on climate change, negotiations inside the Bella Centre are starting to get political.
It's the end of the first week of the historic climate change meeting, and the detailed processing of negotiations going on between different working groups is now transitioning to soon being the work of ministers and leaders.
The Danish Government is not sitting back, and has intervened more than previous host countries of COP events to try and harness the political will and drive home an outcome by this Friday.
Denmark's minister for the conference, Connie Hedergaad, is believed to be holding regular discussions with ministers from throughout the world on what areas of the negotiations are on track, and what still needs work for a deal to be reached.
It's believed Australia's minister for climate change, Penny Wong, has been regularly involved with these discussions.
Today the talks will move from plenary sessions to high-level political discussions.
To date, it's believed ministers have been around but not leading discussions, and the arrival of more than 100 world leaders during the week is unprecedented.
Organisers are now calling COP 15 the biggest intergovernmental meeting in history, bigger than the Versailles meeting at the end of the first World War, and also the meeting of leaders to establish the United Nations.
Protestors marched in a fairly peaceful demonstration from the city to the conference centre, but there were a reported 300 people arrested by police.
Protests are only expecetd to incerase as world leaders begin arriving and the loomong deadline for a deal by Friday approaches.
