Words, but little to write home about from Obama

The informal high-level event hosted by Danish Prime Minister Lars Lokke Rasmussen on Friday gave a platform to leaders of major developed and emerging economies, offering them a chance to show their vision and make pledges for the world to join hands in a strong deal that will guide the international efforts in tackling climate change.

The speeches in a way were a war of different principles between the developed countries - represented by the United States and European Union - and the developing nations - represented by China, Brazil, India and others.

And there was no lack of grandstanding words.
