At the moment delegates from 196 governments are meeting in Lima for the UN climate summit. The aim is that this meeting will be 'stepping-stone' for the United Nations Framework Convention on Climate Change (UNFCC) Paris summit next year, which will hopefully lead to a global climate treaty. The lovely people at the Carbon Brief have put together a road-map of where we've been and where we're hoping to get to for Paris 2015.
Confused about what exactly the UN Lima Climate Talks are discussing? BBC News have made a 60 video (very!) briefly outlining the headline issues being discussed.
