2017 set to be hottest non-El NiÃ±o year, warns UN
The year 2017 is set to be the hottest on record without a natural El NiÃ±o event that releases heat from the Pacific Ocean once every five years, the United Nations has said. "These findings underline the rising risks to life on Earth if we fail to get on track with the aims of the Paris Agreement," the UN added.
