Earth’s fever persisted last year, not quite spiking to a record high but still in the top five or six warmest on record, government agencies reported Thursday.

But expect record-shattering hot years soon, likely in the next couple years because of “relentless” climate change from the burning of coal, oil and gas, U.S. government scientists said.

Despite a La Nina, a cooling of the equatorial Pacific that slightly reduces global average temperatures, the U.S. National Oceanic and Atmospheric Administration calculates 2022’s global average temperature was 58.55 degrees, ranking sixth hottest on record. NOAA doesn’t include the polar regions because of data concerns, but soon will.

If the Arctic – which is warming three to four times faster than the rest of the world – and Antarctic are factored in, NOAA said it would be fifth warmest. NASA, which has long factored the Arctic in its global calculations, said 2022 is essentially tied for fifth warmest with 2015. Four other scientific agencies or science groups around the world put the year as either fifth or sixth hottest.

NASA Administrator Bill Nelson said global temperature is “pretty alarming ... What we’re seeing is our warming climate, it’s warning all of us. Forest fires are intensifying. Hurricanes are getting stronger. Droughts are wreaking havoc. Sea levels are rising. Extreme weather patterns threaten our well-being across this planet.”

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

Last year was slightly toastier than 2021, but overall the science teams say the big issue is that the last eight years, from 2015 on, have been a step above the higher temperatures the globe had been going through. All eight years are more than 1.8 degrees warmer than pre-industrial times, NOAA and NASA said. Last year was 2 degrees warmer than the mid-19th century, NASA said.

In a human body an extra 2 degrees Fahrenheit is considered a fever, but University of Oklahoma meteorology professor Renee McPherson, who wasn’t part of any of the study teams, said the global warmth is actually worse than the equivalent of a planetary fever because fevers can be treated to go down quickly.

“You can’t take a pill for it so the fixes aren’t easy,” McPherson said. “It’s more what you consider a chronic illness like cancer.”

Like a fever, “every tenth of a degree matters and things break down and that’s what we’re seeing,” Climate Central Chief Meteorologist Bernadette Woods Placky.

Vose and NASA Goddard Institute of Space Studies Director Gavin Schmidt both said there are hints of an acceleration of warming but the data isn’t quite solid enough to be sure. But the overall trend of warming is rock solid, they said.

“Since the mid-1970s you’ve seen this relentless increase in temperature and that’s totally robust to all the different methodologies,” Schmidt said.

The La Nina, a natural process that alters weather worldwide, is in its third straight year. Schmidt calculated that last year the La Nina cooled the overall temperature by about a tenth of a degree and that last year was the hottest La Nina year on record.

“The La Nina years of today aren’t the La Nina years of yesterday,” said North Carolina state climatologist Kathie Dello. “Historically, we could rely on La Nina turning down the global thermostat. Now, heat-trapping gases are keeping the temperature cranked up, and handing us another top-10 warmest year on record.”

With La Nina likely dissipating and a possible El Nino on the way — which adds to warming — Schmidt said this year will likely be warmer than 2022.

In the United States, global warming first grabbed headlines when Schmidt’s predecessor, climate scientist James Hansen, testified about worsening warming in 1988. That year would go on to be the record warmest at the time.

Now, 1988 is the 28th hottest year on record.

The last year that the Earth was cooler than the 20th century average was 1976, according to NOAA.
