The world remained firmly in warming’s grip last year, with extreme summer temperatures in Europe, China and elsewhere contributing to 2022 being the fifth-hottest year on record, European climate researchers said this week.
The eight warmest years on record have now occurred since 2014, the scientists, from the European Union’s Copernicus Climate Change Service, reported, and 2016 remains the hottest year ever.
NASA and the National Oceanic and Atmospheric Administration also issued analyses of global temperatures for 2022 on Thursday, and their findings were similar. NASA’s analysis ranked 2022 as tied with 2015 for fifth warmest, while NOAA had last year as the sixth warmest.
“But ranks only tell you part of the story,” said Russell Vose, a NOAA scientist. What’s more important, he said, is that the past eight years are the warmest ever. “They really do stand apart,” he said.
Each of the past four decades has been warmer than one that preceded it, Dr. Vose added.
Overall, the world is now 1.2 degrees Celsius (2.1 degrees Fahrenheit) hotter than it was in the second half of the 19th century, when emissions of planet-warming carbon dioxide from the burning of fossil fuels became widespread.
Carlo Buontempo, director of the Copernicus service, said the underlying warming trend since the pre-industrial age made 2022’s ranking in the top five “neither unexpected or unsurprising.”
“The rare event now would be to see a really cold year,” he said.

“We are continuing the long-term warming trend of the planet,” said Zeke Hausfather, a researcher at Berkeley Earth, an independent organization that analyzes environmental data. “If you draw a straight line through temperatures since 1970, 2022 lands almost exactly on where you’d expect temperatures to be.”
Berkeley Earth also issued its own analysis this week, ranking 2022 as fifth warmest.
Last year was among the warmest despite the persistence of La Niña for the third consecutive year. La Niña is a climate pattern marked by colder-than-normal sea surface temperatures in the equatorial Pacific Ocean that tend to suppress global temperatures.

The Copernicus scientists said Europe had its hottest summer ever in 2022, with several heat waves rolling across the continent that set temperature records in many cities. Separate research has shown that heat waves in Europe are increasing in frequency and intensity at a faster rate than almost anywhere else, fueled by warming but also, most likely, by shifts in atmospheric and oceanic circulation.
The effects of such a warm year were felt elsewhere around the world as well. Eastern and Central China, Pakistan and India all experienced lengthy and extreme heat waves in 2022, and monsoon floods in Pakistan ravaged much of the country. The heat and accompanying dryness also contributed to extensive wildfires in the Western United States.
Methodology
Anomalies are shown relative to the average temperature between 1951 and 1980.
Individual records are taken from weather stations with at least 40 years of continuous operation and a minimum of 183 observations in any given year. Individual maximum temperature observations that failed quality checks were excluded.
Exact weather stations for each city are: Edinburgh Royal Botanic Garden, London Heathrow, Ourense, Madrid Retiro, Almeria Airport, Den Helder, Hamburg Neuwiedenthal, Berlin Buch, Aalborg Airport and Linkoeping Malmslätt.
Regional temperature records were calculated from Copernicus ECWMF's ERA5 Reanalysis 2m temperature data, obtained through the Copernicus Climate Data Store. Maximum temperatures in 2022 were compared with the maximum temperatures for all previous years going back to 1980.
