Antarctica just experienced minus 119 F, Earth's coldest temperature since 2012 — here's why

✇Live Science

While millions around the world grappled with extreme heat this month, a research station in Antarctica recorded Earth's coldest temperature since 2012.

The high-altitude research station, named Concordia, logged a low of minus 119.4 degrees Fahrenheit (minus 84.1 degrees Celsius) on July 18, according to data from the station.

Concordia is located in the interior of the Antarctic continent, which is currently in the dead of winter with no sunlight. Temperatures at the station regularly fall below minus 112 F (minus 80 C) this time of year ‪—‬ so the new reading isn't unprecedented, but it's still significant.

"Even here, where extreme cold is expected, temperatures below minus 84 C are remarkable and highlight how variable Antarctic weather can still be," Gabriele Carugati, the station leader at Concordia for Italy's National Antarctic Research Program (PNRA), told Live Science over a video call from the station.

The French Polar Institute Paul-Émile Victor, which runs Concordia with the PNRA, sent Live Science raw data from July 18, which showed the temperature dropping to minus 84.1 C twice, at 6:25 a.m. and 6:34 a.m. local time.

The extreme chill at Concordia stands in sharp contrast to the sweltering heat that many countries are currently experiencing. North America and Europe have been battling heat waves this summer, with Western Europe recording the hottest June on record. Meanwhile, wildfires are raging in Canada, the U.S., France, Spain and other countries.

Globally, average temperatures are going up as humans pump more heat-trapping greenhouse gases into the atmosphere. However, Earth's weather systems are complex, and climate change doesn't mean that everywhere gets hotter all of the time.

"Climate change describes the long-term global trends, while individual weather events can still [bring] exceptional cold," Carugati said. "Antarctica is influenced by complex atmospheric processes, so an extreme low temperature at one location does not contradict the broader picture of global warming."

"Astronauts of ice"

Concordia is considered the most remote and extreme research station in the world. Built on top of a 10,800-foot-thick (3,300 meters) ice cap, the station is used for a variety of purposes, including seismic observations, astronomy and the modeling of Earth's past climates, according to the French Polar Institute Paul-Émile Victor.

"Concordia is a special place because it sits at over 3,200 meters [10,500 feet] above sea level on the Antarctic Plateau, and more than 1,000 kilometers [600 miles] from the coast," Carugati said. "During winter, there is no sunlight for months, the atmosphere is extremely dry and stable, and under clear skies, heat continuously escapes to space because there are no clouds, allowing temperatures to fall to extraordinary levels."

Concordia's environment is so harsh and isolated that the station is also used to improve our understanding of the physical, mental and social challenges astronauts experience in space. Carugati noted that the only person at the station who is not researching the environment is a European Space Agency biomedical doctor, who is studying the researchers who work there, nicknamed "astronauts of ice."

Planes can't fly to Concordia once winter sets in, and it's around 370 miles (600 kilometers) from the nearest research station. That technically makes crews more isolated than astronauts on the International Space Station, which orbits about 250 miles (400 km) above Earth, according to the European Space Agency.

What is the coldest temperature ever recorded?

The coldest temperature ever recorded at Concordia was minus 120.5 F (minus 84.7 C), logged in the winter of 2010, according to the Italian Antarctic Meteo-Climatological Observatory. However, another high-altitude research station in East Antarctica has the all-time record for the coldest temperature ever recorded on Earth. Russia's Vostok weather station, the nearest station to Concordia, recorded a temp of minus 128.6 F (minus 89.2 C) in July 1983, according to the World Meteorological Organization.

Satellite data suggests that temperatures can drop as low as minus 144 F (98 C) in East Antarctica, according to a 2018 study published in the journal Geophysical Research Letters. However, even though Antarctica is the coldest and driest continent, it's not immune to global warming.

Major glaciers and the ice sheet they support are at risk in West Antarctica, with the Antarctic Peninsula — which extends out of the western side of the continent — experiencing the most rapid warming. A study published in February in the journal Frontiers in Environmental Science found that decisions made on greenhouse gas emissions today will determine how much the peninsula will change in the coming centuries, with sea ice, ice shelves and glaciers, along with the penguins that live on them, at risk of disappearing.

Concordia sits on the largest ice sheet on Earth. This sheet in East Antarctica is more stable than the smaller sheet of West Antarctica, but it is still vulnerable to rising temperatures. An unprecedented Antarctic winter heat wave in March 2024 saw temperatures near Concordia rise to a record high of 15.1 F (minus 9.4 C) ‪—‬ about 32 F (18 C) warmer than the previous March maximum. This East Antarctic heat wave was amplified by global warming, according to a study published in April in the journal npj Climate and Atmospheric Science.

Earth recently entered an El Niño, the warm phase of a multiyear natural climate pattern, which could bring unprecedented temperature extremes to an already-warming world. Carbon Brief, a U.K. based outlet that reports on climate news and policy, has predicted that 2026 is likely to be the second-warmest year on record, behind 2024, with the intensifying El Niño increasing the likelihood that 2027 will be the warmest year ever recorded.

For now, at Concordia, the researchers are continuing their work in the blistering cold of Antarctica's winter. Carugati noted that the latest extreme-temperature data will inform forecasts and long-term climate monitoring.

"Extreme observations like this help scientists better understand atmospheric processes and improve the climate models," he said.

Satellite Images Revealed Something Unusual About the Color of These Antarctic Islands—Here’s the Odd Reason Behind Their Appearance

✇The Debrief
By: Micah Hanks

Seen from space, the Danger Islands along Antarctica’s rocky coastline have a distinctive pink-orange coloration, with tiny trails of pink closer to its shorelines.

However, the unique colors of these islands aren’t attributable to minerals, colorful lichens, or other kinds of usual causes. According to NASA, the Danger Islands look the way they do because of their iconic residents.

Now, data about the influence these creatures have on their surrounding habitat his helping scientists monitor the health of an entire Antarctic ecosystem from space.

A Colorful Surprise Spotted from Space

According to a new study’s findings, the vast colonies of Adélie penguins on the Danger Islands are the culprit behind their coloration. More specifically, it is the guano these flightless birds produce that has permanently altered their coloration when seen from space, resulting in pink stains along the shoreline environments where these waddling creatures reside.

Surprisingly, the guano stains offer an effective means of tracking the diets of these birds, which can serve as a good proxy for the broader changes occurring in Antarctica’s marine environment.

Primarily, this is because these large penguin colonies can deposit enough guano that their presence is detectable in satellite imagery, as is revealed in Landsat satellite imagery collected since the mid 1980s. The distinctive pinkish hue observed on the Danger Islands today indicates a diet rich in krill, whereas eating more fish would produce very different color signatures—all of which can be detected through satellite observations.

Decades of Penguin Activity Revealed

For the new research, scientist Casey Youngflesh with the Department of Biological Sciences at Clemson University, along with her coauthors, analyzed more than three decades of Landsat satellite imagery collected from 1984 through 2013.

These observations, combined with samples collected from field studies involving penguin colonies, helped the researchers establish links between specific color patterns and the balance of krill and fish in the birds’ diets.

Among the team’s findings, the data revealed a very close relationship between penguin food sources and the extent of sea ice in the surrounding area, particularly during the breeding season of these shore-dwelling birds.

Colonies of penguins along the warmer Antarctic Peninsula and West Antarctica—locations where there is less sea ice—revealed a greater reliance on krill. By contrast, Eastern Antarctic penguins consumed more fish in areas where sea ice persisted for longer. This higher-quality food source is also linked to improved chick growth and a greater degree of overall population success in the long term.

“Sea ice is such a hugely important factor in the Antarctic marine environment,” said Youngflesh. “The structure of the region’s food web is changing in response.”

The Future of Antarctic Environments

Along with what the team’s findings reveal about the lives and sustenance patterns of penguins, they also bring to mind several questions about the future of their habitat.

Although sea ice in Antarctica was found to be primarily stable during the years Youngflesh and her team examined, since 2013 it has shrunken significantly, reaching record low levels. Further declines are expected in the decades ahead, signaling changes that could push Adélie penguins toward increasingly krill-dependent diets.

This could become complicated as commercial krill fishing has seen expansion in recent years, and recovering populations of whales and seals are also competing for the same food source.

Right now, researchers are working to produce new computer models based on data obtained from the Landsat 8 and Landsat 9 satellites, which will help them continue to observe penguin diets from orbit. This data provides an unusual—but also a remarkably effective—means of monitoring the changing health of Antarctica’s fragile ecosystem.

The findings were reported in a new study, “Space-based monitoring of penguin diet links sea ice, food webs, and population change,” which appeared in the journal Current Biology on July 20, 2026.
