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.

Latin Music Stars Unite in Miami to Raise Aid for Victims of Venezuela’s Devastating Earthquake
Latin music stars including Marc Anthony, Ricardo Montaner and Feid will take part in a benefit concert in Miami on August 16 to raise funds and support victims of the devastating double earthquake that struck Venezuela.
The disaster has left 4,734 people dead and 16,740 injured, according to the latest official figures.
The lineup will also feature artists such as Jay Wheeler, Elena Rose, Silvestre Dangond, Gente de Zona, Mau y Ricky, Olga Tañón, Lasso, San Luis, Piso 21, Alleh, Zhamira Zambrano and Enrique Santos, with organizers expecting additional performers to join the event in the coming weeks.
Athletes, actors, entertainment figures, media personalities and leaders from the Hispanic community are also expected to participate in the initiative.
Organized by the United for Venezuela coalition, the concert will take place at the Kaseya Center in Miami starting at 6:00 p.m. local time (10:00 p.m. GMT) and will be broadcast simultaneously through multiple platforms.
According to organizers, viewers will be able to contribute through donation platforms and QR codes available during the event.
The concert will also feature reports on rescue efforts, the work of humanitarian organizations on the ground, and testimonies from people affected by the disaster to highlight the scale of the tragedy.
Venezuela was hit on June 24 by a powerful double earthquake measuring 7.2 and 7.5 in magnitude, with the strongest impacts reported in areas including Caracas and La Guaira.

Trump Administration Seeks Global Action Against “Resurgent” Left-Wing Terrorism
U.S. Secretary of State Marco Rubio will host a ministerial meeting in Washington on Thursday to discuss what the Donald Trump administration describes as a growing threat from left-wing terrorism around the world.
According to a statement from the State Department, the meeting aims to promote “stronger joint action” among international partners to address what Washington considers security gaps that terrorist groups continue to exploit.
The U.S. government has not yet disclosed which countries will participate in the meeting or which foreign ministers are expected to attend.
The Trump administration claims that “far-left terrorism is resurging”, pointing to violent attacks linked to extremist movements in the Americas, Europe, Asia, and other regions.
U.S. officials argue that the threat has been “underestimated” by the international community for years as part of broader counterterrorism strategies.
As part of its efforts, the Trump administration has designated several left-wing extremist groups as terrorist organizations, including Antifa Ost, the Informal Anarchist Federation/International Revolutionary Front (FAI/FRI), Armed Proletarian Justice, and Revolutionary Class Self-Defense.
The United States has also announced rewards of up to $10 million for information that helps disrupt the financial networks supporting those organizations.
The meeting comes as the Trump administration seeks greater international cooperation on counterterrorism policies and increased coordination among governments to address what it considers emerging extremist threats.

President Noboa Declares New Security Strategy as Ecuador Faces Record Violence Levels
Ecuadorian President Daniel Noboa on Tuesday declared the National Comprehensive Security Plan 2025-2029 as a nationwide public policy, a strategy aimed at guiding state actions on security matters over the next four years.
The measure was formalized through an executive decree that activates the plan approved on March 9 by the Public and State Security Council (Cosepe) and replaces the National Comprehensive Security Plan 2019-2030, which had been designated as public policy in 2021.
Under the new decree, implementation of the strategy will be led by the ministries of Interior, Defense, and Foreign Affairs and Human Mobility, along with the National Intelligence Center and the National Secretariat for Risk Management. These institutions will be responsible for coordinating actions according to their respective areas of responsibility.
According to the official document, the new plan adopts a multidimensional and comprehensive security approach, with a long-term vision focused on national interests and on strengthening the State’s ability to respond to current threats.
The Ecuadorian government said the strategy seeks to improve coordination among public institutions within the framework of the “internal armed conflict” declared by Noboa in 2024 as part of the fight against criminal organizations operating across the country.
The plan also includes measures to strengthen international cooperation against transnational organized crime, which authorities identify as one of Ecuador’s main security challenges due to its links to drug trafficking and illegal mining.
The government described the document as a roadmap for prevention, protection, response and recovery actions in the face of national security risks, promoting coordinated efforts among state institutions.
Ecuador has remained under an internal armed conflict declaration since 2024, when Noboa intensified operations against criminal gangs that his administration has labeled terrorist organizations. Despite the increased security measures, the country recorded around 9,300 homicides in 2025, the highest figure in its history, according to data from the Ministry of Interior.
The new security plan comes as Ecuador seeks to strengthen its institutional response to escalating violence and the growing influence of organized crime networks.
