A new joint report from Green Alliance, WWF, Christian Aid, RSPB and Greenpeace believes we will have a global agreement on tackling climate change by the end of next year. If we do, it will be an exceptional event. Nations working together is no longer the fashionable way to deal with problems. The UN is looked upon as indecisive, the EU is seen as technocratic and even the United Kingdom is barely living up to its name. And yet the prime minister has just announced he will be heading to New York later this month to meet with other world leaders to discuss getting a global agreement. Why would he bother?
