“As the global climate talks in Copenhagen reach a climax, there is a chorus of agreement from world leaders on the gravity of the global warming crisis, but a tangle of disagreement on how best to iron out an agreement. The talks continued as President Obama headed to Denmark to address the summit Friday, the last day of the gathering. Take, for example, the tensions at play when Secretary of State Hillary Clinton — with negotiations stalled — announced the U.S. would, after all, join an international relief fund aimed at providing $100 billion a year by the year 2020 to help the poorest and most vulnerable nations deal with the advancing impacts of global warming.” (12/17/09)
