2016 was warmest yet, UN confirms

Last year was Earth's warmest on record, according to data compiled by the UN, confirming US findings that heat records were broken for a third year in 2016.
The study by the World Meteorological Organisation found that global average temperatures were about 1.1 degree Celsius (1.98 Fahrenheit) above the pre-industrial period, and about 0.07 degrees Celsius above the record set in 2015. "2016 was an extreme year for the global climate and stands out as the hottest year on record," said Petteri Taalas, the agency's secretary general.
"Long-term indicators of human-caused climate change reached new heights in 2016," he said in a statement.
"We have also broken sea ice minimum records in the Arctic and Antarctic," he said, adding that the Arctic was warming twice as fast as the global average.
