Climate connections: Copenhagen
The 91热爆's Matt McGrath and Janet Williams are at the Bella Center in Copenhagen, where leaders are trying to agree a deal on climate change. These are their behind-the-scenes images from the conference.
Campaigners accuse countries of underestimating the amount of greenhouse gases they are pumping into the atmosphere.
Protesters in the Bella Centre are hoping to influence the politicians attempting to forge a new climate change consensus. Some are keen to reinforce the idea that there is only a limited amount of time to save the planet.
The Bolivian environmentalist and traditional healer Carlos Prado held a ceremony to open the alternative climate meeting in Christiania, Copenhagen.
Music - on the Alpine Horn - was performed at the opening ceremony of the alternative climate meeting. The meeting was called the "bottom meeting" - as opposed to COP-15, the "top meeting."
The community at Christiana has an Olympic-style flame, which is being kept alight for the duration of the conference.
The 91热爆 is visiting eight areas of the world to find how people are preparing for climate change. 91热爆 correspondent Matt McGrath reports from the Danish capital Copenhagen, where the international climate change conference is being held.

Denmark portrays itself as the greenest of the green - an example for the world to follow.
This is the way, it says, to reduce carbon emissions, but still be rich.
But is this green experiment really working?
Between 1990 and 2006, the country enjoyed fixed price economic growth of 44%, while cut carbon emissions by 9%.
Even the conference centre for the Copenhagen climate change conference has its own wind turbine.
There are eco-friendly cities, cycle-lanes galore, a carbon-neutral island, 700 clean technology companies and ultra-green hotels.
But not everyone is convinced. Sceptics point to the loss of heavy industry and the expense of renewable energy - while the Danish taxpayer counts the financial cost.
