'Meaningful' climate deal reached

Politico reports:

The United States, China, India and South Africa have reached a "meaningful" climate change deal that sets a cap on worldwide temperature increases at no more than 2 degrees, contains no binding emissions standards — and a deal one senior administration admitted "is not sufficient" to combat long-term global warming.

The deal was struck after a day of frantic talks — and following a hastily organized multilateral meeting between President Obama, Premier Wen, Indian Prime Minister Singh and President Zuma.
