Indeed, the negotiations may well have raised the curtain on what will be some very difficult discussions when countries come forward with their 'contributions' from the end of next year.
Over the first week of the UN climate change negotiations in Poland we have seen the alarming results of studies showing increased decline of tropical forests.
