There is a 66 percent probability that the annual average global temperature in at least one of the years between 2023 and 2027 will be more than 1.5 degrees. The five-year period as a whole is also likely to be the warmest ever recorded, according to the WMO.
The Paris Agreement sets long-term goals to guide countries to reduce global greenhouse gas emissions to limit global temperature increase this century to two degrees."The WMO, on the other hand, is sounding the alarm that we will pass the 1. 5 degree level on a temporary basis with increasing frequency," said WMO Secretary-General Petteri Taalas.
