The Doha deal also establishes a loss-and-damage mechanism that helps the most vulnerable countries deal with the adverse effects of climate change.

The Doha climate talks are a modest step toward a global climate deal in 2015, said Hedegaard, adding there will be more climate battles in the coming years.
