EU leaders meet to discuss climate change - but the Greek financial crisis overshadows the talks

EU leaders have so far failed to come up with a "fast-start" funding for poorer nations to battle climate change. Despite working overnight, there has been no agreement yet on the initial 6 billion euro funding they hoped to pledge at the Copenhagen Climate summitt. European Union nations have already proposed that 100 billion euros be made available to poorer nations annually by 2020. But a number of EU countries - especially Greece - are struggling with deep deficits and have expressed reservations about taking on any new debt.
