UN Climate Report Delayed by Science Dispute

The publication of a major new U.N. report on climate change is being held up by a battle between rich and developing countries over emissions targets and financial aid to vulnerable nations. The report by hundreds of the world’s top scientists was supposed to be approved by government delegations Friday at the end of a weeklong meeting in the Swiss town of Interlaken. The deadline was repeatedly extended as officials from big nations such as China, Brazil, Saudi Arabia, as well as the United States and the European Union haggled through the weekend over the wording of key phrases in the text.
