'Sirens Are Blaring': WMO Says 2023 Shattered Key Climate Metrics
"Fossil fuel pollution is sending climate chaos off the charts," U.N. Secretary-General António Guterres said.
Mar 19, 2024
Last year broke records for several key climate indicators, including surface temperatures, ocean heat, sea-level rise, and the loss of Antarctic sea ice, the World Meteorological Organization found in its State of the Global Climate 2023 report, released Tuesday.
The agency confirmed that 2023 was the hottest year on record and said it gave an "ominous" new meaning to the phrase "off the charts."
"Earth is issuing a distress call," United Nations Secretary-General António Guterres said in a video statement. "The latest State of the Global Climate report shows a planet on the brink. Fossil fuel pollution is sending climate chaos off the charts. Sirens are blaring across all major indicators."
"The climate crisis is THE defining challenge that humanity faces and is closely intertwined with the inequality crisis."
2023 saw an average global near-surface temperature of 1.45°C, the report found, making 2023 the hottest on record and the cap on the warmest 10-year period on record.
"Never have we been so close—albeit on a temporary basis at the moment—to the 1.5°C lower limit of the Paris agreement on climate change," WMO Secretary-General Celeste Saulo said in a statement. "The WMO community is sounding the red alert to the world."
The European Union's Copernicus Climate Change Service and European Center for Medium-Range Weather Forecasts had found separately that January 2024 capped a 12-month period that exceeded the 1.5°C target for the first time.
2023 was also a particularly alarming year for ocean heat, with nearly a third of the ocean in the midst of a marine heatwave at any time during the year. Global sea-surface temperatures reached record heights for April and every month after, with July, August, and September especially hot. Ocean heat content also broke records, and more than 90% of the ocean experienced a heatwave for at least a portion of the year.
The world's glaciers and sea ice did not fare any better. Glaciers lost the most ice in any year since record-keeping began in 1950, and Antarctica's sea-ice extent at the end of winter smashed the previous record by 1 million square kilometers.
"Because of burning fossil fuels, which leads to CO2-induced global heating, we have impacted the polar regions to such a degree that 2023 saw by far the greatest loss of sea ice in the Antarctic and of land ice in Greenland," University of Exeter polar expert Martin Siegert told Common Dreams. "The world will feel the detrimental effects now and into the future because the changes observed will lead to 'feedback' processes encouraging further change."
"Our only response must be to stop burning fossil fuels so that the damage can be limited," Siegert added. "That is our best and only option."
2023 also saw record sea-level rise and ocean acidification.
"Climate change is about much more than temperatures," Saulo said. "What we witnessed in 2023, especially with the unprecedented ocean warmth, glacier retreat, and Antarctic sea ice loss, is cause for particular concern."
Records were broken too for the main cause of all this warming and melting—the levels of greenhouse gasses in the atmosphere. Carbon dioxide, methane, and nitrous oxide all reached record levels in 2022, and data indicates that the atmospheric concentrations of all three continued to rise in 2023, with carbon dioxide levels 50% higher than before the industrial revolution.
The report also considered the impacts of global heating on extreme weather events: 2023 saw several especially devastating climate-fueled disasters, including lethal flooding from Cyclone Daniel in Libya; Tropical Cyclone Mocha, which displaced 1.7 million people in the region around the Bay of Bengal; an extreme heatwave in southern Europe and North Africa; a record wildfire season in Canada that smothered several North American cities in heavy smoke; and the deadliest U.S. wildfire in more than 100 years in Hawaii.
In addition to claiming lives and forcing people from their homes, these disasters have several other impacts on peoples' well-being. For example, the report noted that the number of people suffering from acute food insecurity had shot up to 333 million in 2023, more than two times the 149 million before the pandemic. While the root causes of this are war and conflict, economic downturns, and high food prices, extreme weather events can make the situation worse. When Cyclone Freddy, one of the longest-lasting cyclones ever, struck Madagascar, Mozambique, and Malawi in February, it flooded vast swaths of agricultural fields and damaged crops in other ways.
"The climate crisis is THE defining challenge that humanity faces and is closely intertwined with the inequality crisis—as witnessed by growing food insecurity and population displacement, and biodiversity loss," Saulo said.
Guterres, meanwhile, said the impact of extreme weather on sustainable development was "devastating."
"Every fraction of a degree of global heating impacts the future of life on Earth," he said.
There was some positive news in the report, mainly that renewable energy increased new capacity by nearly 50% in 2023 compared with 2022, the highest rate of increase in 20 years. Global climate finance nearly doubled from 2019-2020 to almost $1.3 trillion, but this was still only 1% of global gross domestic product.
To have a shot at limiting warming to 1.5°C, finance needs to increase by nearly $9 trillion by 2030 and another $10 trillion by 2050, but this is much lower than the estimated cost of doing nothing, which would be $1,266 trillion from 2025-2100, though the WMO said this was likely a "dramatic underestimate."
Guterres said it was still possible to limit long-term global temperature rise to 1.5°C, but it required swift action; leadership from the G20 nations toward a just energy transition; countries proposing 1.5°C-compliant climate plans by 2025; increased climate finance flows toward the developing world, including for adaptation and Loss and Damage; universal coverage by early warning systems by 2027; and "accelerating the inevitable end of the fossil fuel age."
"There's still time to throw out a lifeline to people and planet," Guterres said, "but leaders must step up and act now."

Alarming Heat Streak Continues as February Shatters Temperature Record
"As remarkable as this might appear, it is not really surprising as the continuous warming of the climate system inevitably leads to new temperature extremes," said the head of the E.U. climate service.
Mar 07, 2024
Last month was the warmest February on record, the European Union’s climate service said Wednesday, marking the ninth consecutive month of unprecedented heat as the climate crisis continues to drive up global temperatures.
Climate scientists say the climate crisis, without a doubt, is to blame for increased temperatures.
Not only was it warm above sea level—global ocean temperatures also reached a record high last month. That's not just for February but for any month on record.
"Ocean warming has prompted concerns about the mass bleaching of coral reefs. It also raises global sea levels and can help to fuel higher intensity hurricanes," the BBCreports. "Unusually warm waters may also have been a factor in another exceptional month for Antarctic sea ice. The three lowest minimum extents in the satellite era have now occurred in the last three years."
The #C3S's monthly climate bulletin is out now:
📈 February 2024 was globally the warmest on record;
📈 Global Sea Surface Temperatures hit record highs.

Arctic sea ice is also disappearing, and the Arctic could be virtually ice-free during the summer within a decade.
"February joins the long streak of records of the last few months," said Carlo Buentempo, director of the Copernicus Climate Change Service. "As remarkable as this might appear, it is not really surprising as the continuous warming of the climate system inevitably leads to new temperature extremes."
“The climate responds to the actual concentrations of greenhouse gases in the atmosphere so, unless we manage to stabilize those, we will inevitably face new global temperature records and their consequences,” Buentempo added.
The last year has been over 1.5°C above pre-industrial averages—1.56°C, to be exact—but that won't signify a breach of the goals set in the Paris Agreement unless temperatures remain elevated for the next few years.
"A year ago, the fact that the global temperature for a particular month would reach 1.5°C above the pre-industrial level would have been considered exceptional," Julien Nicolas, a senior scientist at Copernicus, toldThe New York Times.
The world will have to get off of fossil fuels in order to halt runaway warming, and this year could help determine the future of the climate, considering one of the people running to lead the nation appears destined to unleash billions of tons of additional planet-warming emissions should he return to office.

'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 toldThe 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 Dreamsreported 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 BBCrevealed 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 toldNPR 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.
