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.

Beyond the place where the American continent ends, on Navarino Island, crossing the Beagle Channel, Puerto Williams stands as the southernmost city in the world, a place far from pollution and human mistreatment, with unique conditions for the study of climate change.

U.S. Sanctions Network Linked to Fentanyl Trafficking Across India, Guatemala and Mexico
The United States Department of State announced sanctions on Thursday against 23 individuals and companies allegedly linked to an international fentanyl production and smuggling network operating in India, Guatemala and Mexico.
According to the State Department, the network supplied precursor chemicals to the Sinaloa Cartel, which the United States has designated as a Foreign Terrorist Organization.
Washington declared fentanyl, a powerful synthetic opioid, a weapon of mass destruction last year due to its role in the ongoing overdose crisis in the United States.
“By targeting the entire supply chain — from chemical suppliers in Asia to logistical intermediaries in Central America and cartel-linked networks in Mexico — the Trump Administration is dismantling networks that destabilize governance across our hemisphere and threaten U.S. security,” the State Department said.
In a separate statement, the Office of Foreign Assets Control detailed sanctions against three Indian chemical and pharmaceutical companies: Sutaria, Agrat and SR Chemicals, along with a sales executive accused of supplying precursor chemicals to contacts in Guatemala and Mexico.
In Guatemala, authorities sanctioned J and C Import and Central Logística de Servicios, as well as intermediary Jaime Augusto Barrientos.
The OFAC also designated several intermediaries and import companies operating in the Mexican state of Sinaloa.
As part of the investigation, U.S. authorities identified Ramiro Baltazar Félix as a member of Los Mayos, a faction of the Sinaloa Cartel, and Alejandro Reynoso, accused of operating clandestine drug laboratories in Guadalajara.

Pope Leo XIV Says Countries Have Border Rights but Migrants Deserve Respect
Pope Leo XIV said Thursday that migrants must be treated with dignity as he addressed the global migration crisis during a press conference aboard the plane returning from his tour of Africa.
The pontiff answered questions from journalists regarding his upcoming trip to Spain, which will include a visit to the Canary Islands, a region heavily affected by migration flows and growing political polarization surrounding the issue.
“Obviously, migration is a very complex issue and affects many countries — not only Spain, not only Europe, but also the United States. It is a global phenomenon,” the pope said.
Pope Leo XIV also questioned the role of developed nations in addressing the crisis.
“My response begins with a question: What is the Global North doing to help the Global South and those countries where young people no longer see a future and dream of going north, even when the North sometimes has no answers to offer?” he asked.
While acknowledging that “a state has the right to establish rules for its borders,” the pope insisted that the debate must go beyond border control and address the structural causes that force people to leave their home countries.

Authorities Say Teotihuacán Gunman Was Obsessed With Mass Shootings and Extremist Symbolism
Julio César Jasso Ramírez, identified by authorities as the gunman behind the armed attack at the archaeological site of Teotihuacán, had allegedly spent years building a personal narrative shaped by an obsession with historical mass shootings, extremist symbolism, and an increasing detachment from reality.
According to preliminary findings from the Fiscalía General de Justicia del Estado de México, the 27-year-old suspect, originally from the southern Mexican state of Oaxaca, acted alone and appeared to have carefully planned the attack.
Investigators also pointed to signs of a severe psychological or psychiatric disorder. One official involved in the case stated that the suspect seemed to live in “his own reality,” disconnected from the world around him.
“I would not speak of a motive; I would speak of psychopathy, a condition, an illness,” the official said while discussing the ongoing investigation.
Authorities reported that Jasso Ramírez was allegedly fixated on mass violence incidents that occurred outside Mexico, particularly in the United States.
Among the items found in his possession were writings, images, and materials reportedly linked to the Columbine High School massacre, the school shooting that took place on April 20, 1999.
The investigation remains ongoing as authorities continue analyzing evidence connected to the suspect’s background and mental state.
