Reuters – President Barack Obama addresses the session of United Nations Climate Change Conference 2009 in Copenhagen … 
COPENHAGEN – A senior Obama administration official says the U.S., China, India and South Africa have reached a "meaningful agreement" on climate change.
The official characterized the deal as a first step, but said it was not enough to combat the threat of a warming planet.
Details of the deal with these emerging economies were not immediately clear.
The agreement was reached Friday at the U.N. climate conference in Copenhagen after a meeting among President Barack Obama and Chinese Premier Wen Jiabao, Indian Prime Minister Manmohan Singh (MUHN'-moh-hahn sing) and South African President Jacob Zuma (ZOO'-muh).
The official spoke on condition of anonymity because the agreement had not yet been officially announced.
The agreement was with the smaller group of countries, but was being worked by Obama and various negotiating teams with a larger number of countries, the official said.
