UN: US must be part of climate change agreement

Any agreement hammered out by a massive United Nations climate change conference starting in Indonesia this week would not make sense without the participation of the US, the world’s top emitter of greenhouse gases, the UN’s climate chief said today.

Delegates from 190 nations will gather on the resort island of Bali on Monday for the largest global warming conference ever, bringing more than 10,000 people together for two weeks of marathon discussions, including Hollywood stars, former US Vice President Al Gore, fishermen and drought-stricken farmers.
