OSLO (Reuters) - Last year was the second or third warmest on record behind 2016, and the hottest without an extra dose of heat caused by an El Niٌo event in the Pacific Ocean, the United Nations said on Thursday.
Average surface temperatures in 2017 were 1.1 degree Celsius (2.0 Fahrenheit) above pre-industrial times, creeping towards a 1.5C (2.7F) ceiling set as the most ambitious limit for global warming by almost 200 nations under the 2015 Paris climate agreement.
