Chile’s distant paradise where scientists study climate change

Hidden inside pristine forests in Chile’s deep south, known as the end of the world, lie potential early warning signs of climate change. Puerto Williams on Navarino island, which is separated from the South American mainland by the Beagle Channel, is the world’s southern-most town.
Far from the pollution that blights major urban and industrial centers, it is a paradise that provides unique conditions to study global warming.
“There is nowhere else like it,” Ricardo Rozzi, director of the Cape Horn International Center for global change studies and bio-cultural conservation in Puerto Williams, told AFP.
It is “a place that is especially sensitive to climate change” as average temperatures do not rise above five degrees Celsius. This cold and windy area is the last inhabited southern frontier before reaching the Antarctic.
The ethnobotanical Omora park is home to an immense variety of lichens, mosses and fungi that scientists study by crouching down onto their knees with magnifying glasses.
In the crystal clear Robalo river, minuscule organisms act as sentinels of the changes produced by global warming. In both the park and river, the alarm bells are ringing.
Moss and lichen on the move
At this latitude — 55 degrees south — climate change has an exponential effect on flora that react by seeking out low temperatures, said Rozzi, 61. “The most obvious aspect of climate change is the rising temperatures,” he said. “These lichens cannot survive” if a certain threshold is passed. To escape the higher temperatures, they move.
“In the case of (mosses) we’ve noticed that they have moved. Before they were between 50 and 350 (meters above sea level) and now they are between 100 and 400,” said Rozzi. He says Omora has more diversity per square meter of lichens and mosses than anywhere else in the world. They also help to absorb carbon dioxide.
Another aspect is the elevational diversity gradient, an ecological pattern in which biodiversity changes with elevation.
The 700-meter high Bandera hill’s biodiversity changes every 200 meters and there is a mammoth 1.5 degrees Celsius difference in temperature between top and bottom.
“We can see what changes happen in the high mountains and in the area close to the sea in a very short distance, and we can see how the temperature affects the biodiversity that lives in this river,” Tamara Contador, 38, a biologist at the Cape Horn International Center, told AFP.
She studies the gradients themselves. If the height difference between gradients rises or falls on the mountain, scientists can determine whether there has been a global change in temperature. They say there has been.
Avoiding ‘extermination’
“On a global level, the polar and subpolar ecosystems are the most affected by climate change, so we are in a place where climate change has a much bigger effect on biodiversity than other places,” said Contador.
River organisms also form part of the alert system.
“The organisms that live here are also indicators of water quality and global environmental change,” added Contador.
River organisms move about and have already increased their reproductive cycle, says Rozzi. This confirms there has been a small change to the climate in the area that could have been much greater elsewhere on the planet.
“Some insects that have an annual eggs to larvae to adulthood cycle are now having two cycles because the temperature has risen,” said Rozzi.
By studying these organisms and learning from them “we can avoid crossing the threshold that brings us to the extermination of humanity and other life forms,” he added.

Trump Orders Construction of New ‘Golden Fleet’ to Revitalize U.S. Naval Superiority
President Donald Trump issued an executive order this Monday for the immediate construction of two new warships that will bear his name. These vessels will be the pioneers of what he described as the “Golden Fleet,” a future generation of “Trump-class” battleships that he claimed would be “100 times more powerful” than those currently in service.
The announcement took place at his private residence in Mar-a-Lago, Florida. The President indicated that following the initial two ships, the administration aims to commission up to 25 additional vessels. He is scheduled to meet with Florida-based contractors next week to expedite production, criticizing existing defense firms for failing to deliver results efficiently.
This naval expansion is a cornerstone of Trump’s goal to revitalized the American shipbuilding industry and address the strategic gap between the U.S. and competitors like China.
The move comes amid heightened geopolitical tension. Just last week, Trump ordered the seizure of all sanctioned tankers involved with Venezuela’s “ghost fleet” to cripple the country’s crude oil industry. Since December 10, the U.S. military—deployed in the Caribbean under the guise of counter-narcotics operations—has already detained two tankers linked to Venezuelan oil transport.

U.S. Judge Blocks ICE from Re-detaining Salvadoran Erroneously Deported Under Trump Administration
A U.S. federal judge ruled this Monday, December 22, that Immigration and Customs Enforcement (ICE) is prohibited from re-detaining Salvadoran national Kilmar Ábrego García, who was erroneously deported to El Salvador earlier this year during the administration of President Donald Trump.
During a hearing in Maryland, U.S. District Judge Paula Xinis ruled that Ábrego García must remain free on bail through the Christmas holidays, concluding that his initial detention lacked a legal basis. The ruling follows a request from his legal team for a temporary restraining order to prevent ICE from carrying out a new arrest.
Earlier this month, on December 11, Judge Xinis ordered his release from a Pennsylvania migrant detention center after determining that the government had detained him without a formal deportation order. In 2019, an immigration judge had already ruled that Ábrego could not be returned to El Salvador because his life was in danger.
Despite that protection, Ábrego García was deported in March 2025 following a raid by the Trump administration. Officials argued at the time that he was a gang member, and he was sent directly to the Center for the Confinement of Terrorism (CECOT) in El Salvador. In June, he was returned to the United States to face a new trial for alleged human smuggling—a charge he denies.
On Monday, Judge Xinis also temporarily invalidated a new deportation order issued by an immigration judge following Ábrego’s recent release, granting him legal protection through the coming weeks. His trial is scheduled to begin in Tennessee in January 2026.

Fire at substation triggers major blackout in San Francisco
The U.S. city of San Francisco was plunged into darkness Saturday night after a power outage left about 130,000 customers without electricity, although the utility company said service was restored to most users within hours.
Pacific Gas & Electric Company (PG&E) said in a statement posted on X that nearly 90,000 homes had their power restored by 9:00 p.m. local time (05:00 GMT on Sunday), while the remaining 40,000 customers were expected to have service restored overnight.
Large areas of the city, a major technology hub with a population of around 800,000, were affected by the blackout, which disrupted public transportation and left traffic lights out of service during the busy weekend before Christmas, a crucial period for retail businesses.
“I know it’s been a difficult day,” San Francisco Mayor Daniel Lurie said in a video posted on social media from the city’s emergency operations center. “There has been progress, but for those still without power, we want to make sure they are safe and checking in on their neighbors,” he added.
Lurie said police officers and firefighters advised residents to stay home as much as possible. He also noted that officers and traffic inspectors were deployed to manage intersections where traffic lights were not functioning.
The mayor confirmed that the outage was caused by a fire at an electrical substation. Parts of the city were also covered in fog, further complicating conditions during the incident.
As a result of the blackout, many businesses were forced to close despite it being the weekend before Christmas. The sudden drop in shopper traffic ahead of the holiday is “devastating” for retailers, the manager of home goods store Black & Gold told the San Francisco Chronicle.
