Chile’s distant paradise where scientists study climate change
AFP | Alberto Peña
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.

Top U.S. Military Commander Meets Interim Venezuelan Leaders After Maduro’s Capture
The commander of the United States Southern Command, Marine Francis L. Donovan, visited Venezuela on Wednesday, holding meetings with interim leaders following the recent capture of former President Nicolás Maduro by U.S. forces. The visit, confirmed by both U.S. and Venezuelan officials, marked a significant diplomatic and security engagement in Caracas.
Donovan, accompanied by senior U.S. officials including acting Assistant Secretary of Defense Joseph M. Humire and top diplomat Laura Dogu, met with acting President Delcy Rodríguez and key members of her cabinet, including Defense Minister Vladimir Padrino López and Interior Minister Diosdado Cabello.
According to official statements, discussions focused on strengthening bilateral cooperation on regional security issues, including efforts to combat illicit drug trafficking, terrorism, and migration. Both sides reiterated a commitment to pursuing diplomatic engagement and shared security goals for Venezuela and the Western Hemisphere.
The meetings also discussed progress on a three-phase plan supported by the United States to help stabilize Venezuela, following Maduro’s removal from power and subsequent detention in the U.S. on drug-related charges. This agenda reflects expanding U.S. engagement with Venezuela’s interim government amid broader efforts to restore diplomatic relations and address regional challenges.
The visit concluded on Wednesday, underscoring a growing U.S. focus on cooperation with Venezuelan authorities in the aftermath of major political developments earlier this year.

Bayly Says Trump ‘Gets Along Better With Dictators’ and Criticizes U.S.–Venezuela Policy
Peruvian author and journalist Jaime Bayly said Tuesday in Madrid that U.S. President Donald Trump “gets along better with dictators than he does with democrats” and that his administration is experiencing “a honeymoon with the Venezuelan dictatorship,” according to a report on his remarks during the launch of his new novel Los golpistas (Galaxia Gutenberg).
Bayly made the comments while presenting the book, which reconstructs the turbulent three days in April 2002 when Venezuelan leader Hugo Chávez briefly lost power. He also sharply criticized the current Venezuelan leadership, saying that Delcy Rodríguez should be recognized as a dictator and “a continuation of Maduro’s dictatorship.”
The writer lamented that the failed 2002 coup — which he described as carried out by “amateurs” — did not lead to free elections that might have restored democracy to Venezuela. He argued that, even now, U.S. policy under Trump seems more focused on securing access to Venezuelan oil than on supporting Venezuelans’ freedom. “Venezuela could have chosen a free, clean and legitimate government — which we still impatiently await despite Trump, who only seems interested in freeing Venezuelan oil, not Venezuelans,” Bayly said.
Bayly also claimed that “every day that passes, Trump seems more enchanted with Delcy,” suggesting that Washington might leave Venezuelan leaders in power so long as they cooperate on economic interests.
A U.S. citizen who has lived in Miami for decades, Bayly said he is proud never to have voted for Trump, whom he described as “servile with the powerful and cruel with the weak.” He also criticized U.S. immigration enforcement as abusive.
Regarding the book’s creative process, Bayly said he combined extensive documentation and interviews with historical events, weaving fictional dialogue and narrative into real episodes without altering core facts. Los golpistas explores why the April 2002 coup attempt against Chávez failed and how key figures such as Chávez and Cuban leader Fidel Castroshaped modern Venezuelan history.

Maduro and Cilia Flores Receive Consular Visit in U.S. Jail Ahead of March 26 Hearing
Venezuelan President Nicolás Maduro, who is detained in the United States, and his wife, Cilia Flores, received a consular visit from a Venezuelan government official on January 30 while they remain in a New York jail awaiting their next court appearance, scheduled for March 26, 2026, according to a court filing.
The notification, submitted to the judge by prosecutors and the defense and now part of the digital case file, states that Maduro and Flores were visited by “an official representing the Republic of Venezuela to help facilitate any services the accused needed.”
The document also notes that U.S. District Judge Alvin Hellerstein ordered the U.S. prosecutor’s office at the couple’s first court appearance on January 5 to ensure they had access to consular services and to inform the court when such access was provided.
Their next hearing was postponed by the court from an original date of March 17 to March 26 at 11:00 a.m., after prosecutors, with the consent of the defense, requested extra time to gather evidence, allow the defense to review it, and determine which pretrial motions they will file, the filing says.
Maduro has denied wrongdoing, calling himself “innocent” of the narcotics charges authorities have brought in federal court.
