It is near-certain that 2023-2027 will be the warmest five-year period ever recorded, the United Nations warned Wednesday as greenhouse gases and El Nino combine to send temperatures soaring.
There is a two-thirds chance that at least one of the next five years will see global temperatures exceed the more ambitious target set out in the Paris accords on limiting climate change, the UN’s World Meteorological Organization (WMO) said.
The hottest eight years ever recorded were all between 2015 and 2022, with 2016 the warmest — but temperatures are forecast to increase further as climate change accelerates.
“There is a 98-percent likelihood that at least one of the next five years, and the five-year period as a whole, will be the warmest on record,” the WMO said.
The 2015 Paris Agreement saw countries agree to cap global warming at “well below” two degrees Celsius above average levels measured between 1850 and 1900 — and 1.5C if possible.
The global mean temperature in 2022 was 1.15C above the 1850-1900 average.
The WMO said there was a 66 percent chance that annual global surface temperatures will exceed 1.5C above pre-industrial levels for at least one of the years 2023-2027, with a range of 1.1C to 1.8C forecasted for each of those five years.
