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.

French Parliament Moves to Approve Social Media Age Limit for Minors
France’s Parliament is expected to approve legislation on Tuesday banning children under the age of 15 from accessing social media platforms, following an agreement reached Monday between lawmakers on the mechanism to enforce the measure.
The initiative is part of President Emmanuel Macron’s broader effort to strengthen online protections for minors and regulate children’s screen time before the end of his second presidential term in May 2027.
“Tomorrow, France will become the first country in Europe to establish a digital age of majority to better protect our children online,” Digital Affairs Minister Anne Le Hénanff said Monday in a post on X.
If approved, the government plans to implement the restriction in September, when students return to school after the summer holidays.
The United Kingdom has already passed similar legislation restricting social media access for users under the age of 16, although that measure is scheduled to take effect in early 2027.
Both the National Assembly, France’s lower house of Parliament, and the Senate are expected to hold final votes on the legislation Tuesday after a joint committee of seven senators and seven lawmakers reached an agreement on the bill’s final wording.
Under the proposed law, children under 15 years old would be prohibited from accessing online social media services, with limited exceptions for certain platforms, including online encyclopedias.
The legislation would make France the first member of the European Union to introduce a nationwide minimum digital age for access to social media platforms, reflecting a growing international movement to strengthen online safeguards for children and teenagers.

WHO to Hold New Round of Talks After Slow Progress on Pandemic Accord
Member states of the World Health Organization (WHO) made limited progress during the seventh session of the Intergovernmental Working Group (IGWG) tasked with finalizing a key annex to the global pandemic agreement, prompting negotiators to schedule another round of talks in September.
The session, which opened on July 6 and concluded last week at WHO headquarters in Geneva, focused on drafting and negotiating the annex covering the Pathogen Access and Benefit-Sharing (PABS) System, a central component of the pandemic accord.
Without the completion of the PABS annex, the global pandemic agreement cannot enter into force.
The annex had originally been expected to be finalized before May 2026, but negotiations have progressed more slowly than anticipated.
In a statement, the WHO said member states “advanced negotiations” on the PABS system while acknowledging that additional discussions are required to complete a framework capable of supporting a faster, more effective and more equitable response to future pandemics.
The organization announced that an eighth round of negotiations will take place on September 14.
Despite the limited progress, delegates succeeded in streamlining the draft text and concentrating discussions on several technical issues.
According to the WHO, negotiators focused on the contractual arrangements underpinning the PABS mechanism, the laboratory networks responsible for handling and sharing pathogens and their genetic sequence data, as well as the framework for distributing the benefits generated through the sharing of those pathogens.
The PABS system is considered one of the most important elements of the future pandemic agreement, as it aims to ensure timely access to pathogens for scientific research while establishing fair mechanisms for sharing the benefits derived from vaccines, diagnostics and other medical countermeasures developed during future global health emergencies.

Iran Says It Is in “Full-Scale War” as U.S. Launches Ninth Consecutive Night of Airstrikes
Iran declared on Monday that it is facing a “full-scale war” against the United States after Washington carried out another wave of overnight airstrikes, including attacks near a city that hosts one of the country’s nuclear facilities.
Iranian President Masoud Pezeshkian said the country must prepare for the consequences of the ongoing conflict, describing the situation as a broad military confrontation.
“The reality is that today the Islamic Republic of Iran is engaged in a full-scale war,” Pezeshkian said in a statement released by the presidency. “We must be realistic and accept the natural consequences of this resistance.”
The latest U.S. strikes marked the ninth consecutive night of military operations, according to the U.S. Central Command (CENTCOM), which announced the attacks on X.
Since hostilities resumed on July 7, U.S. air operations have expanded well beyond southern Iran, reaching central and northwestern regions of the country, according to local sources.
Local authorities reported that one person was killed and several others injured in Tabriz, in northwestern Iran, more than 1,000 kilometers from the Persian Gulf.
Additional casualties were reported in the nearby city of Urmia, where several people were wounded during separate strikes.
Washington said the attacks targeted military installations. However, Iranian officials accused the United States of striking populated areas, including Bushehr, home to Iran’s only operational nuclear power plant.
Iran also reported that the Darkhovin nuclear facility, which is still under construction, was among the sites hit during the latest attacks.
U.S. President Donald Trump said on Sunday that the renewed military campaign was carried out in honor of American service members killed in recent days.
Two U.S. soldiers died on Friday during attacks on a military base in Jordan, while another service member was killed on Sunday during the controlled disposal of unexploded munitions from an Iranian drone in northern Iraq.
According to U.S. figures, 17 American troops have been killed since the conflict began on February 28.
On the Iranian side, the latest official figures released on Friday reported 50 deaths and more than 500 injuries since fighting resumed earlier this month.
A memorandum of understanding signed by Iran and the United States on June 17, which had been intended to pave the way for peace negotiations, collapsed after hostilities resumed over the strategic control of the Strait of Hormuz, one of the world’s most important energy shipping routes.
