Can they make a difference? With hours to go to strike a deal on climate change, the pressure is mounting on world leaders to save the Copenhagen summit.
As they arrived for a gala dinner, frantic negotiations were taking place behind the scenes.
There appears to be some progress, but big choices must still be made if a meaningful agreement is to be reached.
“We are walking a tight rope. There are still substantive differences, but I have seen nothing to indicate that we cannot breach this gap. World leaders have come to Copenhagen because they want an agreement,” UN Secretary-General Ban Ki- moon said.
Earlier, US Secretary of State Hillary Clinton pledged a global warming fighting fund for poorer countries, tied to certain requirements.
“In the context of a strong accord…the United States is prepared to work with other countries toward a goal of jointly mobilising 100 billion dollars a year by 2020 to address the climate change needs of developing countries,” she said.
But, overcoming outstanding differences between the US and China, particularly on monitoring developing countries’ emissions curbs, remains key to any deal. Many will be hoping that US President Barack Obama can break the deadlock in the Danish capital.
