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.

Meta Says Russia Seeks to Ban WhatsApp for Defending Secure Communication
U.S. tech giant Meta, the parent company of WhatsApp, said that Russia is seeking to ban the messaging app because it “challenges government attempts to violate people’s right to secure communication.”
Russian authorities have encouraged citizens to switch to state-backed applications, and in August they already blocked WhatsApp’s calling feature.
On Friday, the communications regulator Roskomnadzor claimed that the platform was being used to “organize and carry out terrorist acts in the country, recruit perpetrators, and facilitate fraud and other crimes.”
“If the messaging service does not comply with Russian law, it will be completely blocked,” the regulator warned.
WhatsApp remains one of Russia’s most widely used messaging services, alongside Telegram.
Moscow is pressuring both platforms to grant authorities access to user data upon request for investigations into fraud and activities the government labels as “terrorist.”
Human rights advocates fear the demand could be used to target critics of the Kremlin, President Vladimir Putin, or the war in Ukraine.

Archbishop Wenski criticizes Trump’s deportation policies, calls for stronger push for reform
The Archbishop of Miami, Thomas Wenski, has called for increased pressure on the U.S. Congress to advance comprehensive immigration reform and criticized President Donald Trump’s mass deportation policies, arguing that they “do nothing to help.”
“We need to apply more pressure on Congress so lawmakers can make the necessary changes. It is also important for the Administration to listen to our voice. We do not want to be anyone’s enemy—we are Americans,” Wenski said in an interview with EFE.
The religious leader, who heads one of the dioceses with the largest Latino and Haitian populations in the United States, issued a call to defend the rights of migrants. He also emphasized that the U.S. Conference of Catholic Bishops (USCCB) has maintained a strong and public stance in favor of migrants for decades.

Trump relaunches diplomatic push to finalize U.S.-Backed peace plan for Ukraine War
U.S. President Donald Trump announced on Tuesday that his diplomatic team will resume meetings with delegations from Russia and Ukraine in an effort to pressure both sides to accept the peace plan proposed by Washington to end the war in Ukraine.
As part of this new round of talks, U.S. Special Envoy Steve Witkoff will travel to Moscow to meet with Russian President Vladimir Putin. Meanwhile, Army Secretary Dan Driscoll will hold discussions with Ukrainian representatives to narrow differences on the remaining points of the agreement.
Trump also confirmed his intention to meet personally with Ukrainian President Volodymyr Zelensky and with Putin, though he emphasized that such meetings will only take place “when the agreement is fully finalized or in its final stage.”
The president claimed that his administration has made “tremendous progress” toward resolving the conflict and reiterated that the war “never would have started” if he had been in the White House at the onset of the crisis.
The U.S.-backed peace plan consists of 28 points and has been revised following feedback from both sides. According to Trump, only “a few points of disagreement” remain under active discussion.
One of the most controversial aspects of the proposal is the suggestion that Ukraine cede parts of the Donbas region to Russia and limit the size of its armed forces. Kyiv is working closely with Washington to soften these clauses in search of an arrangement that does not compromise its sovereignty or security.
With this diplomatic push, Trump aims to solidify his role as the main mediator in the conflict and steer the war toward a political resolution after years of devastation, humanitarian crisis, and rising global geopolitical tensions.
