"The United Nations will have an extra round of climate change talks this April in Germany to speed up stalled climate negotiations.
'The decision to intensify the negotiating schedule underlines the commitment by governments to move the negotiations forward toward success' at a major climate conference in Mexico at the end of the year, Yvo de Boer, the United Nations' top climate change official, said in a statement.
The extra summit will be April 9-11 in Bonn, ahead of 2-week negotiation scheduled to take place in the western German city at the end of May.
The next major climate summit is to take place Nov. 29-Dec. 10 in Cancun, Mexico. It is expected to draw world leaders trying to agree to an ambitious global climate protection deal."
