'Never Happened Before': WMO Finds Past 10 Years Have Been 10 Hottest on Record
"While a single year above 1.5°C of warming does not indicate that the long-term temperature goals of the Paris agreement are out of reach, it is a wake-up call," wrote the secretary-general of the World Meteorological Organization.
Mar 19, 2025
A report released by the World Meteorological Organization on Tuesday found that not only was 2024 the warmest year in a 175-year observational period, reaching a global surface temperature of roughly 1.55°C above the preindustrial average for the first time, but each of the past 10 years was also individually the 10 warmest on record.
"That's never happened before," Chris Hewitt, the director of the WMO's climate services division, of the clustering of the 10 warmest years all in the most recent decade, told The New York Times.
All told, the agency's State of the Global Climate 2024 adds new details to the public's understanding of a planet that is getting steadily warmer thanks to human-caused greenhouse gas emissions.
2024 clearly surpassed 2023 in terms of global surface temperature. 2023 recorded a temperature of 1.45°C above the average for the years 1850-1900, which is used to represent preindustrial conditions, according to the report.
The report from the WMO, a United Nations agency, includes "the latest science-based update" on key climate indicators, such as atmospheric carbon dioxide, ocean heat content, and glacier mass balance. Many of these sections report grim milestones.
In 2023, the atmospheric concentration of carbon dioxide reached the highest levels in the last 800,000 years, for example, and in 2024, ocean heat content reached the highest level recorded in the over half-century observational period, topping the previous heat record that was set in 2023.
As of 2023, two other greenhouse gases, methane and nitrous oxide, also reached levels unseen in the last 800,000 years.
"Over the course of 2024, our oceans continued to warm, sea levels continued to rise, and acidification increased. The frozen parts of Earth's surface, known as the cryosphere, are melting at an alarming rate: glaciers continue to retreat, and Antarctic sea ice reached the second-lowest extent ever recorded. Meanwhile, extreme weather continues to have devastating consequences around the world," wrote WMO Secretary-General Celeste Saulo in the introduction to the report, which drew its findings from data drawn from dozens of institutions around the world.
"While a single year above 1.5°C of warming does not indicate that the long-term temperature goals of the Paris agreement are out of reach, it is a wake-up call that we are increasing the risks to our lives, economies and the planet," wrote Saulo.
In 2015, 196 party countries signed on to the agreement to pursue efforts "to limit the temperature increase to 1.5°C above preindustrial levels." According to the United Nations, going above 1.5ºC on an annual or monthly basis doesn't constitute failure to reach the agreement's goal, which refers to temperature rise over decades.
There are multiple methods that aim to measure potential breaches of 1.5°C over the long term, according to the report. The "best estimates" of current global warming based on three different approaches put global temperatures somewhere between 1.34°C and 1.41°C compared to the pre-industrial period.
The report also details the damage brought on by a number of extreme weather events last year, including Hurricanes Helene and Milton in the United States, and Cyclone Chido, which impacted the French territory of Mayotte.

Chevron CEO Pay Jumped to $26.5 Million During Hottest Year on Record
News of Mike Wirth's 2023 compensation came after March was deemed the 10th month in a row to be the hottest ever recorded.
Apr 10, 2024
The chief executive of the U.S. oil giant Chevron saw his pay jump by more than 12% in 2023 as continued emissions from fossil fuel corporations helped push global temperatures to record heights.
Citing a new securities filing, Reuters reported Wednesday that Chevron CEO Mike Wirth received $26.5 million in total compensation last year. Chevron, the second-largest oil company in the U.S. by revenue, reported $21.3 billion in profits in 2023—a haul it used to lavish shareholders with buybacks and dividends.
News of Wirth's 2023 compensation came a day after the European Union's Copernicus Climate Change Service (C3S) announced that last month was the hottest March on record globally. The organization said March marked "the 10th month in a row that is the warmest on record for the respective month of the year."
Samantha Burgess, deputy director of C3S, said in a statement that "March 2024 continues the sequence of climate records toppling for both air temperature and ocean surface temperatures."
"Stopping further warming requires rapid reductions in greenhouse gas emissions," Burgess stressed.
But oil giants like Chevron, the primary drivers of the global climate emergency, have been rolling back their already tepid climate commitments and buying up rival oil producers—a signal that the industry is bent on continuing to drill as much as possible despite increasingly dire warnings from scientists.
A Carbon Majors report released earlier this week found that Chevron is one of just 57 oil, gas, coal, and cement producers responsible for 80% of global CO2 emissions from those industries.
A separate analysis published last month by Global Witness estimated that the emissions of Chevron, Shell, TotalEnergies, ExxonMobil, and BP could cause 11.5 million additional premature deaths around the world before the end of the century.
"In the past few months, ExxonMobil and Chevron have invested more than $100 billion into new oil and gas reserves," the human rights group noted. "BP and Shell weakened their climate pledges. And TotalEnergies plans to ramp up production in the next few years."
"Fossil fuel companies' systematic spreading of climate change denial, combined with lobbying, has slowed the transformation towards an energy system built on renewables," Global Witness added. "And yet, the supermajors are asking us to trust them, to allow them to be the ultimate arbiter, despite the massive profits they're making."
'Omen of the Future': Off-The-Charts Hot Oceans Scare Scientists
After 2023 was the hottest year in human history, experts warn that 2024 "has strong potential to be another record-breaking year."
Feb 27, 2024
While global policymakers continue to drag their feet on phasing out planet-heating fossil fuels, scientists around the world "are freaking out" about high ocean temperatures, as they told The New York Times in reporting published Tuesday.
A "super El Niño" has expectedly heated up the Pacific, but Times reporter David Gelles spoke with ocean experts from Miami to Cambridge to Sydney about record heat in the North Atlantic as well as conditions around the poles.
"The sea ice around the Antarctic is just not growing," said Matthew England, a University of New South Wales professor who studies ocean currents. "The temperature's just going off the charts. It's like an omen of the future."
Rob Larter, a marine geophysicist with the British Antarctic Survey who watches polar ice levels, told the paper that "we're used to having a fairly good handle on things. But the impression at the moment is that things have gone further and faster than we expected. That's an uncomfortable place as a scientist to be."
\u2026for almost a year now,\u201d McNoldy said. \u201cIt\u2019s just astonishing. Like, it doesn\u2019t seem real.\u201d Across the unusually warm Atlantic, in Cambridge, England, @rdlarter , a marine scientist who tracks polar ice levels, is equally perplexed. \u201cIt\u2019s quite scary, partly because\u2026— (@)
Last week, Jeff Berardelli, WFLA's chief meteorologist and climate specialist, also highlighted the warm North Atlantic and that "all signs are pointing to a busy hurricane season" later this year.
Noting that in the middle of this month, sea surface temperatures in the North Atlantic were around 2°F higher than the 1990-2020 normal and nearly 3°F above the 1980s, Berardelli explained:
That may not sound like a lot, but consider this is averaged over the majority of the basin shown in the red outline in the image above. A deviation like that is unheard of... until now.
To put it into more relatable terms, considering what's been normal for the most recent 30 years, the statistical chance that any February day would be as warm as it is right now is 1-in-280,000. That's not a typo. This is according to University of Miami researcher Brian McNoldy...
And that 1-in-280,000 is compared against a recent climate, which had already been warmed substantially by climate change. If you tried to compare it against a climate considered normal around the year 1900, the math would become nonsensical. Meaning an occurrence like this simply would not be possible.
McNoldy also stressed the shocking nature of current conditions to the Times, telling Gelles that "the North Atlantic has been record-breakingly warm for almost a year now... It's just astonishing. Like, it doesn't seem real."
The new comments from McNoldy and other scientists come on the heels of various institutions and experts worldwide recently confirming that 2023 was the hottest year in human history. Research also showed that it was the warmest year on record for the oceans, which capture about 91% of excess heat from greenhouse gases.
As Common Dreams reported last month, Adam Scaife, a principal fellow at the United Kingdom's Met Office, said that "it is striking that the temperature record for 2023 has broken the previous record set in 2016 by so much because the main effect of the current El Niño will come in 2024."
That's the warm phase of the El Niño Southern Oscillation, a climate phenomenon that also has a cool phase called La Niña expected later this year. Still, Scaife warned that "the Met Office's 2024 temperature forecast shows this year has strong potential to be another record-breaking year."
Throughout the record-shattering 2023, experts also expressed alarm. After an April study showed that the ocean is heating up faster than previously thought, the BBC revealed that some scientists declined to speak about it on the record, reporting that "one spoke of being 'extremely worried and completely stressed.'"
In July, when a buoy roughly 40 miles south of Miami recorded a sea surface temperature of 101.1°F just after a "100% coral mortality" event at a restoration site, Florida State University associate professor Mariana Fuentes told NPR that "if you have several species that are being impacted at the same time by an increase in temperature, there's going to be a general collapse of the whole ecosystem."
The following month, the European Union's Copernicus Climate Change Service announced that the average daily global ocean surface temperature hit 69.7°F, and deputy director Samantha Burgess said, "The fact that we've seen the record now makes me nervous about how much warmer the ocean may get between now and next March."
"The more we burn fossil fuels, the more excess heat will be taken out by the oceans, which means the longer it will take to stabilize them and get them back to where they were," Burgess emphasized at the time.
Last year ended with a United Nations climate summit that scientists called "a tragedy for the planet," because the final deal out of the conference—led by an Emirati oil CEO—did not demand a global phaseout of fossil fuels.
Azerbaijan, which is set to host this year's U.N. conference in November, has similarly selected a former fossil fuel executive to lead the event. The country also plans to increase its gas production by a third during the next decade.
