United Nations Secretary-General Ban Ki-moon speaks at the high-level segment of the United Nations Conference on Climate Change in Lima, capital of Peru Dec. 9, 2014. The draft pact to reach in Lima is vital as it will provide a sound basis for a binding climate agreement in Paris in 2015, United Nations Secretary-General Ban Ki-moon said Tuesday, urging negotiators at a UN climate conference in Peru to take united action to produce a balanced and coherent draft text.
