Hundreds of protesters angered by the lack of progress on a climate deal amid political wrangling are marching on the UN climate summit today in Copenhagen. “Activists have been angered by the lack of progress on a new climate deal, and with logistical problems at the summit. Talks are deadlocked over emission cuts and financial aid for poorer countries. And as environment ministers and their aides join the talks, the Danish authorities have slashed the number of campaigners allowed into the venue. Meanwhile, UN Secretary-General Ban Ki-moon has suggested that poor countries may have to give up their hope of getting immediate long-term financial commitments from richer countries. The amount of aid rich nations will pay poorer ones to combat global warming has been one of the main stumbling blocks at the summit.”
