The United States will submit plans for slowing global warming to the United Nations early this week but most governments will miss an informal March 31 deadline, complicating work on a global climate deal due in December. Other emitters such as China, India, Russia, Brazil, Canada and Australia say they are waiting until closer to a Paris summit in December, meant to agree a global deal. Late submissions complicate the Paris summit because it will be far harder to judge late INDCs. --Alister Doyle and Valerie Volcovici, Reuters, 29 March 2015
