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.

Afghan man sentenced to life in prison for deadly Munich vehicle attack
A German court on Thursday sentenced an Afghan man to life imprisonment for a 2025 attack in which he drove a vehicle into a trade union demonstration in Munich, killing two people and injuring around 40 others.
The Munich Higher Regional Court ruled that the 25-year-old man, identified only as Fahrad N. under German privacy laws, committed a particularly serious crime.
Presiding judge Michael Höhne said the court was convinced that the defendant deliberately drove his vehicle into the protesters from behind. He described the scene of the attack as a “real field of destruction.”
The verdict followed the request of federal prosecutors, while the defense had sought a 15-year prison sentence and admission to a psychiatric hospital.
Fahrad N. was convicted of two counts of murder and 23 counts of attempted murder, one more charge than prosecutors had requested. He was also found guilty of 19 counts of serious bodily harm and three counts of intentional injury.
The attack occurred on February 13, 2025, as Munich prepared to welcome international leaders attending the Munich Security Conference, while Germany was entering the final stage of its parliamentary election campaign.
That morning, around 1,400 people were marching through the city center in a demonstration organized by the services union Verdi. According to investigators, the Afghan national drove a BMW Mini past police officers escorting the march before intentionally crashing into the crowd.
The vehicle traveled approximately 23 meters before coming to a stop.
Fahrad N., who was interested in bodybuilding, arrived in Germany at the age of 15 as an unaccompanied minor and had his residence permit renewed. Authorities had previously considered him “well integrated” into local society.
Investigators said he later became radicalized under the influence of Afghan clerics he followed on social media in the months before the attack.
According to prosecutors, the defendant believed Western countries were responsible for the suffering of Muslim populations in Afghanistan and the Middle East, and concluded that he should “kill randomly selected people in Germany.”

Mexican TikTok Influencer Shot Dead While Livestreaming in Sinaloa
A Mexican influencer was shot dead Tuesday night while livestreaming on social media outside a restaurant in the violence-plagued state of Sinaloa, in northwestern Mexico.
César Gastelum, who had more than 500,000 followers on TikTok, was broadcasting live with two friends while taking part in a challenge in which they dressed as food delivery workers. During the livestream, a motorcycle carrying two individuals stopped beside them, and the driver shot Gastelum in the head.
The broadcast was interrupted immediately after the attack and was later removed by the platform. However, several news outlets preserved parts of the footage and shared images of the incident.
Initial reports from local police indicated that a delivery worker had been killed. However, after reviewing the recording and gathering witness statements, authorities identified the victim as Gastelum, who was approximately 25 years old, according to local media reports. The influencer was known for sharing lifestyle-related content.
The attack took place in a busy shopping area near the Sinaloa Attorney General’s Office in Culiacán, the state capital. Military and police forces were deployed to the scene, while forensic experts collected evidence and removed the victim’s body, according to local television reports.
Sinaloa has been experiencing a wave of violence for the past two years due to internal disputes within the powerful local drug cartel.
Local media have reported that around a dozen influencers, some allegedly linked to criminal groups, have been killed in recent years in the state.

Iran Rejects Negotiations With U.S. as Strait of Hormuz Remains Blocked Amid New Attack
Tensions remained high in the Strait of Hormuz on Monday after a vessel was hit by a projectile, despite U.S. President Donald Trump’s claims that negotiations with Iran were moving forward and that the strategic maritime route could reopen as early as Tuesday.
Tehran denied that direct talks were taking place, but Trump insisted that discussions were underway and described the situation as a final opportunity for Iran to reach an agreement.
“This is the last chance they have to sign a good document,” Trump told reporters at the White House, adding that the reopening of the Strait of Hormuz could happen “literally tomorrow” Tuesday.
The comments came after another escalation in rhetoric from Washington. Last week, Trump threatened Iran with military strikes before unexpectedly changing course on Sunday and announcing that negotiations with Tehran would resume.
Iranian Foreign Ministry spokesman Esmail Baqai rejected the U.S. president’s version of events, stating that Tehran was not holding negotiations with Washington.
“At this moment, we are not negotiating with the United States. We are negotiating with Oman to guarantee safe passage through the Strait of Hormuz,” Baqai said.
Earlier, the Iranian official said that Tehran was close to reaching an agreement with Oman, which lies across the Strait of Hormuz, to reopen the crucial waterway that plays a key role in global energy trade.
The maritime route has remained blocked by Iran since the outbreak of hostilities following U.S. and Israeli strikes against the Islamic Republic on February 28.
Meanwhile, Yemen’s Houthi rebels announced Tuesday that they had launched an attack against an airport in Saudi Arabia. The Iran-backed group had previously disrupted the passage of Saudi vessels through the Red Sea, an alternative route used for crude exports by the world’s largest oil producer.
The continued instability in the region has raised concerns over global energy supplies, as the Strait of Hormuz remains one of the most important chokepoints for international oil shipments.
