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.

Tensions Escalate in Middle East as U.S. Bombs Iran After Maritime Attacks
The United States launched new strikes against Iran on Wednesday, following President Donald Trump’s warning that Washington would “hit hard” against the Islamic Republic. While Trump ordered the retaliation after attacks on vessels in the Strait of Hormuz, he also said he hoped the latest wave of bombings would end soon and left the door open for renewed negotiations.
U.S. forces “have begun carrying out additional strikes against Iran to further reduce its ability to threaten freedom of navigation in the Strait of Hormuz,” the United States Central Command said in a post on X.
Washington blamed Iran for what it described as “recent unjustified aggression against commercial shipping.”
Iran’s state news agency IRNA reported that explosions were heard in the port cities of Bandar Abbas, Konarak, and Chabahar.
“This is in retaliation for yesterday’s bombing of ships by Iran. If it happens again, it will be much worse,” Trump wrote on social media alongside an image showing what appeared to be a bombing at an Iranian location.
Before ordering the strikes, the U.S. president said that the ceasefire with Iran had ended. Mediators Pakistan and Qatar called for de-escalation, while the United Nations also urged both sides to reduce tensions.
The Strait of Hormuz remains a critical flashpoint in the Middle East conflict, which began in late February after U.S. and Israeli strikes that killed Iran’s Supreme Leader Ali Khamenei.
Iran-linked attacks on at least three vessels in recent days triggered a U.S. offensive against Iranian targets on Tuesday. Tehran responded by launching attacks against Gulf countries that are allies of Washington.

Deadly Drug Trade Rivalry Suspected After Eight Bodies Discovered in Southern Mexico
Eight bodies were found Wednesday along a highway in the southern Mexican state of Chiapas, near the border with Guatemala, in an incident authorities believe may be linked to a dispute over local drug sales.
The victims — six men and two women — were found abandoned on a road in a mountainous area of the municipality of El Bosque, according to the state prosecutor’s office in a statement published on Facebook.
Initial investigations indicate that the killings may be connected to “a dispute over retail drug sales between local criminal groups operating in the region,” the prosecutor’s office said.
Local media reports that several criminal incidents have increased in the area since the beginning of the year.
The road where the bodies were discovered is located in a mountainous region largely inhabited by Indigenous communities. Authorities have not released further details about the victims or possible suspects as the investigation continues.

Regional Naval Operations Strike Drug Cartels, Disrupting Cocaine and Weapons Trafficking Routes
Transnational operations carried out by regional naval forces, including El Salvador’s National Navy, the United States Coast Guard, and Mexico’s Secretariat of the Navy (SEMAR), have dealt significant blows to international drug trafficking organizations.
The operations have not only led to the seizure of massive cocaine shipments, such as the 6.68 metric tons of cocaine valued at approximately $167 million presented last Wednesday by El Salvador’s Security Cabinet, but have also resulted in the confiscation of high-powered weapons allegedly intended as payment to criminal organizations, according to Security Minister Gustavo Villatoro.
“Based on the strength of the data, not just the narratives, we can state that our National Navy has documented the only known operation in the Pacific Ocean in which a criminal organization from the south was transporting drugs and exchanging them with a group from the north for firearms,” Villatoro said.
The exchange of weapons for drugs between criminal groups in the Pacific Ocean represents a logistical method in which South American cartels from countries such as Colombia and Ecuador negotiate with Mexican and Central American organizations to trade military-grade weapons for cocaine shipments.
Regional naval authorities have identified that meeting points located farther from the coastline in international waters make it easier for armed groups to receive supplies and carry out exchanges undetected. As a result, El Salvador’s National Navy deploys teams from the Trident Naval Task Force (FTNT) aboard maritime patrol vessels to intercept these operations.
Initially, the patrol units are ordered to travel up to 200 nautical miles offshore, but later receive instructions from the Maritime Operations Center to extend their missions beyond 1,000 nautical miles, reaching coordinates used by drug trafficking vessels operating in the open sea.
“We cannot lose focus on the routes these criminal organizations use to move drugs,” Minister Villatoro said, emphasizing the importance of maintaining surveillance over the various maritime corridors used for narcotics trafficking.
