These last seven years, from 2015 to 2021, have been the warmest on record, although the meteorological phenomenon “La Niña” brought down temperatures last year temporarily, the UN confirmed this Wednesday.
The UN World Meteorological Organization (WMO) also mentioned that the first three places in the classification correspond to 2016, 2019 Y 2020.
The organization underlines that “for the seventh consecutive year, the global temperature exceeded pre-industrial levels by more than one degree Celsius”.
“The episodes of La Niña that occurred consecutively meant that, compared to recent years, the warming experienced in 2021 was relatively less pronounced“, clarified the WMO Secretary General, petteri Taalas.
“Even so, 2021 was hotter than previous years, in which the effects of La Niña were felt”, he added.
This shows, he insisted, that “long-term global warming as a result of the increase in greenhouse gas concentrations greenhouse effect is now much greater than the interannual variability of global average temperatures caused by climatic conditions of natural origin”.
La Niña causes a drop in water temperature in the central and eastern Pacific Ocean, which has a meteorological impact on the entire planet.
This phenomenon, which has the opposite impact to that of El Niño, which causes global warming, usually occurs once every two to seven years, but it has occurred or twice from 2020.
