(EPA-EFE photo)BONN: This year will be among the three hottest on record in a new sign of man-made climate change that is aggravating "extraordinary weather" such as hurricanes, droughts and floods, the United Nations said on Monday. "2017 is set to be in top three hottest years," the UN's World Meteorological Organization (WMO) said, projecting average surface temperatures would be slightly less sweltering than a record 2016 and roughly level with 2015, the previous warmest. And 2017 would be the hottest on record without a natural El Nino event that releases heat from the Pacific Ocean about once every five years, it said. "Many of these events -- and detailed scientific studies will determine exactly how many -- bear the tell-tale sign of climate change caused by increased greenhouse gas concentrations from human activities," he said. A few places had record cold against the overall warming trend, such as -25.4C in Bariloche, Argentina, in July.
