On the 12th local time, the Geneva-based World Meteorological Organization pointed out that according to data from six major international temperature datasets integrated by the agency, driven by rising greenhouse gas concentrations and accumulated heat, the past eight years (2015 to 2022) 2009) were the eight warmest years on record globally.
The average global temperature in 2022 is approximately 1.15°C above pre-industrial (1850-1900) levels.
According to all data sets compiled by the World Meteorological Organization, 2022 is the eighth consecutive year (2015 to 2022) in which annual global temperatures were at least 1 degree Celsius above pre-industrial levels.
Over time, it is increasingly likely that the Paris Agreement limit of 1.5 degrees Celsius will be temporarily breached.
The persistence of the cooling La Niña event, now in its third year, means that 2022 will not be the warmest year on record, but "only" the fifth or sixth warmest.
But this cooling effect will be short-term and will not reverse the long-term warming caused by record levels of heat-trapping greenhouse gases in the atmosphere.
The WMO El Niño/La Niña Update indicates that there is about a 60% probability that the La Niña phenomenon will persist from January to March 2023, after which ENSO neutral conditions (neither El Niño nor La Niña) should occur.
The 10-year global average temperature from 2013 to 2022 was 1.14°C above the pre-industrial baseline from 1850 to 1900, compared with the IPCC Sixth Assessment Report estimate of 1.09°C (2011 to 2020), This suggests that long-term warming is continuing.
