2016 possibly hottest year on Earth ever, officials say

CNN — This year is “very likely” to be the hottest year on record, breaking the record set last year, the United Nations weather agency said Monday.

“Long-term climate change indicators are also record breaking. Concentrations of major greenhouse gases in the atmosphere continue to increase to new records. Arctic sea ice remained at very low levels, especially during early 2016 and the October re-freezing period, and there was significant and very early melting of the Greenland ice sheet,” the World Meteorological Organization said in a statement.

If 2016 does indeed set a new record, 16 of the 17 hottest years on record will have been in this century, the WMO said.
