Next Five Years Will Be Hottest Period Ever – UN

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.

Global temperatures are soon set to exceed the more ambitious target set out in the Paris climate accords, with a two-thirds chance that one of the next five years will do so, the UN’s World Meteorological Organization (WMO) said.

The hottest eight years ever recorded were all between 2015 and 2022 – but temperatures are forecast to increase further as climate change accelerates.

“There is a 98-per cent 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 WMO said there was a 66 per cent 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.
