The heat of the earth continued last year. Although it didn’t soar to record highs, 2022 was still among the top five or six warmest on record, government agencies reported Thursday.
The National Oceanic and Atmospheric Administration (NOAA) has found that the global average temperature for 2022 will be 14.76 degrees Celsius (58.55 degrees Fahrenheit), the sixth hottest on record.
NOAA does not include polar regions due to data concerns, but plans to do so soon.
NOAA says it will be the fifth warmest if you include the Arctic and Antarctic, which are warming three to four times faster than the rest of the world.
NASA, which has long taken the Arctic into account in its global calculations, says 2022 will effectively be the fifth hottest year on record, compared to 2015.
Four other scientific institutions or scientific groups around the world rank this year as the fifth or sixth hottest.
“2022 is another Top 10 year” Gavin Schmidt, Director of NASA’s Goddard Space Institute, said:
“It ranks fifth, roughly together with 2015. The warmer years are 2016 and 2020, which are first in line, and 2019 and 2017 were significantly warmer. Another top decade that cements the long-term trend that has been seen: eight consecutive years from the 1970s to the late 19th century were more than 1 degree Celsius higher than the late 19th century, which is the announced 1.5 ( Celsius) would be pretty close to guidelines like the Paris Agreement.”
This will result in a slight drop in average global temperature despite a strong La Niña (cooling of the equatorial Pacific) in 2022.
This is in stark contrast to El Niño, Pacific warming that typically peaks in December.
Berkeley Earth, a nonprofit organization of independent scientists, said it was the fifth hottest on record. 28 countries had the hottest years on record, including China, the UK, Spain, France, Germany and New Zealand.
“So we’re warming at about 0.2 degrees Celsius per decade. A little more than that. And the impact of El Niño and La Niña is about a third of that. That’s about a third of the decade. Only 1 would have to go, and the long-term trend would offset the impact of the La Niña. It was a massive El Nino. Schmidt.
Last year was slightly hotter and wetter than 2021, but the scientific team as a whole said the big deal was that it was one step above the warmer temperatures the planet has experienced in the past eight years since 2015. says.
According to NOAA and NASA, all of these eight years have been more than 1 degree Celsius (1.8 degrees Fahrenheit) warmer than pre-industrial times.
Last year was 1.1 degrees Celsius (2 degrees Fahrenheit) warmer than the mid-19th century, according to NASA.
Schmidt’s role at NASA includes overseeing temperature data collection for calculating annual averages.
“We get weather station records from countries all over the world. We get ocean vessel records from all over the world. Ocean buoys, the Argo float network that tracks what’s happening in the ocean right now. To summarize: fix non-climatic things like moving stations from one place to another, changing instruments, changing methodologies, etc. We try to include those things. Taken together, we have these records that go back at least to the late 19th century,” he says.
And this data is directly correlated with the extreme weather events that occur throughout the year.
“We’re talking mostly about global averages, but no one lives on global averages: heat waves in Europe, fires in Europe, warmest years in the UK, floods in Pakistan, and others. In places, the Pacific Northwest experienced another heat wave and fires, all of which are related to local temperature,” Schmidt said.
La Niña 3 years in a row.
Schmidt calculated that last year’s La Niña lowered overall temperatures by about 0.06 degrees Celsius (0.01 degrees Fahrenheit), making it the hottest La Niña year on record.
“Therefore, we expect 2023 to be warmer than 2022, partly because the La Niña is less intense and partly because the long-term trend continues for another year,” says Shmidt. .
Schmidt says there are signs that warming is accelerating, but the data aren’t strong enough to say for sure. But the overall trend of warming is solid.
Schmidt’s predecessor, climate scientist James Hansen, testified in 1988 about worsening warming.
That year was the warmest on record for its time.
1988 is now the 28th hottest year on record.
