66% chance world exceeds warming threshold before 2027, WMO says
May 18 (ZFJ) — There is a 66% chance that the annual global surface temperature will exceed 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial levels before 2027, said the World Meteorological Organization on Wednesday.
The UN weather agency also predicted that there is a 98% chance that one of the next five years will be the warmest on record.
