Governments from around the world are gathering in the Polish capital, Warsaw, for the United Nation's annual climate change talks.
 
Previous meetings have been criticised for failing to meet agreements on cuts to greenhouse-gas emissions, and activists say this year will be no different.
 
Some campaigners are also concerned about the venue and the funding of these talks.
