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.

Appeals Court blocks Trump’s White House ballroom project without congressional approval
A U.S. appeals court ruled Friday that President Donald Trump must obtain approval from Congress before moving forward with his plan to build a large ballroom on the White House grounds, at the site where the East Wing of the presidential residence previously stood.
The decision was issued in a 2-1 ruling, with the judges determining that a project of such magnitude falls under Congress’ authority and cannot be carried out solely through executive action.
In its ruling, the court sided with the National Trust for Historic Preservation, the organization that filed the lawsuit seeking to halt the construction. The judges found that the plaintiffs had convincingly demonstrated that Congress had never granted the executive branch the authority to “redesign or rebuild the White House, the People’s House, to satisfy the wishes of any particular president.”
Following the decision, Trump announced that he would appeal the ruling to the U.S. Supreme Court, calling the decision incorrect.
“We will immediately appeal it to the Supreme Court,” the president wrote in a message posted on his social media platforms.
Trump also argued that the ruling could pose a security risk to the presidential complex, claiming that it threatens the safety of White House employees, future workers, visitors, heads of state, and other dignitaries.
The president has repeatedly said that the project would not require taxpayer funding and that its financing would come from private donations by business leaders close to his administration, including Amazon founder Jeff Bezos.
However, a previous estimate published by The Washington Post placed the project’s cost at approximately $600 million and suggested that nearly half of the funding could come from public resources, contradicting Trump’s claims.

Rubio warns Cuba U.S. pressure campaign will continue through Trump’s term
U.S. Secretary of State Marco Rubio said Friday that the Cuban government will not find a way out of the pressure campaign imposed by Washington and warned that waiting for the end of President Donald Trump’s second term will not change the situation for the island.
In an interview with U.S. outlet Axios, Rubio said the American administration will continue blocking any mechanisms Cuba uses to ease the impact of sanctions and other measures implemented by Washington.
Rubio argued that Havana can no longer rely on the possibility that time will bring a change in U.S. policy.
“Without a doubt, this situation is not going to disappear in the next two and a half years,” Rubio said, referring to the remaining period of Trump’s current term.
The U.S. official also said Cuba is facing an increasingly difficult scenario following the capture of former Venezuelan President Nicolás Maduro by U.S. forces in January. According to Rubio, the event led to new restrictions on oil supplies to the island, worsening Cuba’s economic and energy crisis.
Rubio’s comments come amid continued tensions between Washington and Havana, with the U.S. government maintaining its policy of sanctions and diplomatic pressure on the Cuban authorities.

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.”
