The world could see average global temperatures 1.5 degrees Celsius above the pre-industrial average for the first time in the coming five years, the U.N. weather agency said Thursday.

The region reached a record high of 18.3 C.

The average global temperature in 2019 was 1.1C above pre-industrial levels, creeping towards a globally agreed limit after which major changes to life on Earth are expected.

As if to underscore the seriousness of the problem, the U.N.’s World Meteorological Organization released a science report Sunday showing that in the last several years, warming, sea level rise and carbon pollution have all accelerated.

Guterres said this means the world is on track for the period from 2015 to 2019 “to be the five hottest years on record.”

United Nations says the world is on track for a temperature rise of about three degrees by 2100.

Tropical storms were solely given female names until the late 1970s.

In just about 80 years Toronto’s summer highs will be the same as Belize’s current summers, if carbon pollution continues to rise.

The Earth is on track to see another year of extreme and unusual weather trends in 2017, say experts at the World Meteorological Organization (WMO).

2016 is set to break the record for the hottest year since measurements began in the 19th century, according to the World Meteorological Organization.
