US officials fear that international climate change talks will become focused on payouts for damage caused by extreme weather events exacerbated by global warming, such as the category 5 Typhoon Haiyan that hit the Philippines last week killing thousands of people and causing what is expected to be billions of pounds of damage. An official US briefing document obtained by the Guardian reveals that the country is worried the UN negotiations, currently under way in Warsaw, will "focus increasingly on blame and liability" and poor nations will be "seeking redress for climate damages from sea level rise, droughts, powerful storms and other adverse impacts". --Stephen Leahy,The Guardian, 13 November 2013
