An excerpt from the letter states:
In November, 2008, President-elect Obama gave an inspiring video address to the Bi-Partisan Governors Global Climate Summit in Los Angeles, California. He said that "Few challenges facing America – and the world – are more urgent than combating climate change,” and pledged that “once I take office, you can be sure that the United States will once again engage vigorously in these negotiations, and help lead the world toward a new era of global cooperation on climate change."
Three years later, America risks being viewed not as a global leader on climate change, but as a major obstacle to progress. U.S. positions on two major issues – the mandate for future negotiations and climate finance – threaten to impede in Durban the global cooperation so desperately needed to address the threat of climate change.
