The global average temperature is set to rise to at least 1.2 to 1.3 degrees Celsius over next 5 years.

The global average temperature is set to rise to at least 1.2 to 1.3 degrees Celsius above pre-industrial levels over the next five years, a World Meteorological Organization (WMO) official said on Monday.

"Basically we are on track to reach at least 1.2- 1.3 degrees centigrade (above pre-industrial levels) over the next five years," said Omar Baddour, WMO senior scientific officer, in response to a Reuters question.

The comments came after the U.N. agency released a report on Sunday showing that the period from 2015-2019 is set to be the warmest five-year period on record, rising by 0.2 degrees Celsius over 2011-2015.
