The EU has agreed a conditional deal on how much it will pay to help other countries fight global warming, ahead of a key climate summit in December. The EU agreed climate change would need 100bn euros annually by 2020 and that it would pay 22bn to 50bn euros a year, conditional on other nations' actions. UK PM Gordon Brown said the EU was leading the way with bold proposals. Talks at the EU summit in Brussels had been deadlocked over how EU nations would share its costs. No cost targets for individual EU nations were announced. But European Commission President Jose Manuel Barroso said the agreement was "an important breakthrough that brings new momentum". He said the EU nations had "agreed a negotiating mandate" for the Copenhagen climate talks. Source: BBC
