Global temperatures made 2022 the sixth warmest year on record

One of the six sets of data comes from the Met Office and the University of East Anglia, which found 2022 was another “near record”, with the year believed to be the sixth warmest since 1850.

The global average temperature was 1.16°C above pre-industrial levels, making 2022 the ninth consecutive year that the global average temperature was 1°C or more above the 19th-century baseline, the Met Office said.

The University of Reading has released the latest version of the now famous ‘Climate Stripes’ graph, including 2022 using the Met Office figures, which inventor Professor Ed Hawkins said showed ‘strong’ global warming.

Overall, the six international datasets consolidated by the United Nations’ World Meteorological Organization (WMO) found that the average global temperature in 2022 was about 1.15°C above 1850-1900 levels.

Despite a La Nina — a cooling of the equatorial Pacific that slightly lowers average global temperatures — the U.S. National Oceanic and Atmospheric Administration (NOAA) calculated a global average temperature of 14.76°C for 2022, making it the sixth warmest year on record who makes records.

NASA, which has long included the Arctic in its global calculations, said 2022 will be essentially the fifth warmest with 2015.

Currently, NOAA does not include the polar regions in its calculations due to data issues.

If the Arctic, which is warming three to four times faster than the rest of the world, and Antarctica are included, it would be the fifth warmest, according to NOAA.

Records from both NOAA and NASA go back more than a hundred years to 1880.

NASA Administrator Bill Nelson said the global temperature is “quite alarming… What we’re seeing is our warming climate, it’s a warning to all of us.”

He added: “Wildfires are increasing, hurricanes are getting stronger, droughts are wreaking havoc, sea levels are rising, extreme weather patterns are threatening our well-being on this planet.”

Berkeley Earth, a nonprofit group of independent scientists, said it was the fifth warmest year on record, noting it was the hottest year on record for 28 countries, including China, France, Germany, Spain, New Zealand and the United Kingdom.

According to the World Meteorological Organization, the likelihood of the world exceeding the 1.5°C warming threshold set in 2015 is increasing every year.

The United Nations Meteorological Agency said the average for the past decade was 1.14 degrees warmer than in pre-industrial times.

Gavin Schmidt, director of NASA’s Goddard Institute of Space Studies, said there is evidence of accelerating warming, although the data isn’t robust enough to be sure.

Nonetheless, he added that the overall warming trend is concrete.

“Since the mid-1970s, you’ve been seeing this relentless rise in temperature, and it’s absolutely robust to all the different methods,” he said.
