Yvo de Boer, head of the UN's climate change convention, announced on Thursday that he would resign from his position as of July 1.

Recent climate change negotiations are delivering "encouraging developments," said the head of the UN Framework Convention on Climate Change.

UN leaders are thrilled that the president-elect of the United States is making climate change a priority and has already pledged to reduce emissions sharply by 2020.

Efforts to fight climate change must not be allowed to falter amid the global financial crisis, said Yvo de Boer, Executive Secretary of the U.N.’s Framework Convention on Climate Change.

The U.N. climate chief announced Thursday that he is encouraged by the climate views of Republican John McCain and Democrats Barack Obama and Hillary Rodham Clinton.
