GENEVA: Despite La Nina’s cooling influence, the United Nations announced on Wednesday that the last seven years had been the warmest ever recorded.
UN’s World Meteorological Organization said, “the warmest seven years have all occurred since 2015.”
The World Meteorological Organization (WMO) reported that despite the fact that two consecutive La Nina occurrences drew worldwide attention, 2021 was still one of the seven hottest years on record.
This year’s warming was less extreme than in prior years because of back-to-back La Nina occurrences. Despite that, WMO Director Petteri Taalas noted in a statement that 2021 was warmer than past years, even after being affected by La Nina. This, he said, shows that “the overall long-term warming because of greenhouse gas increases is now far larger than the year-to-year variability in global average temperatures caused by naturally occurring climate drivers.”
The term “La Nina” refers to a period of widespread cooling of the equatorial Pacific Ocean’s surface temperatures in the central and eastern hemispheres. Normally occurring every two to seven years, but twice since 2020, this event has the reverse effect of warming El Nino.
This week, the US National Oceanic and Atmospheric Administration (NOAA) and the European Union’s Copernicus climate monitor (C3S) both released comparable findings that were used by the World Meteorological Organization (WMO).
In 2021, worldwide temperatures were 1.11 degrees Celsius above pre-industrial levels calculated between 1850 and 1900.
According to the datasets, last year was the sixth year in a row that global temperatures exceeded pre-industrialised levels by greater than 1 degree Celsius.
“The global average temperature in 2021 is already approaching the lower limit of temperature increase the Paris Agreement seeks to avert,” the WMO warned. Developed nations agreed to limit global warming to “well below” 2 degrees Celsius over pre-industrial levels, and 1.5 degrees Celsius if possible, in the 2015 Paris Agreement.
According to the World Meteorological Organization (WMO), there has been a long-term rise in global temperatures that has been uninterrupted for the past seven years. Temperatures have risen steadily since the 1980s, it claimed.
“It’s expected to continue like this.” This year was one of the seven warmest on record, with C3S placing it in fifth place, NOAA placing it in sixth place, and others placing it seventh.
Using these datasets, the WMO says, “the slight discrepancies showed the margin of error in computing the average global temperature between them.”
A number of temperature records and extreme weather occurrences connected to climate change were set in 2021, even though it was the coolest of the top seven warmest years.
