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.

Foro Penal Reports 404 Political Prisoners Still Held in Venezuela
The Venezuelan human rights organization Foro Penal, which leads legal defense efforts for political prisoners in the country, reported on Wednesday that 404 people remain imprisoned for political reasons, five fewer than the figure released a week earlier. Among those detained are 39 foreign nationals or individuals with dual citizenship.
According to data published by the organization, the current total includes 369 men and 35 women being held on political grounds. The report also indicates that 225 of the detainees are civilians, including one teenager, while 179 are members of the military.
Foro Penal stated that 167 of the prisoners have been convicted, whereas 237 remain behind bars without a final sentence. The organization also noted that it has documented 19,102 politically motivated detentions in Venezuela since 2014.
The updated figures come amid an ongoing process of prisoner releases announced by Venezuelan authorities. Two weeks ago, National Assembly President Jorge Rodríguez said that approximately 300 detainees would be freed as part of a new round of releases, separate from those granted under an amnesty approved earlier this year.
Days later, acting President Delcy Rodríguez stated that the number of releases would reach 500 in the coming days. However, relatives of political prisoners and human rights organizations have questioned the pace of the process, arguing that the number of verified releases remains significantly lower than the figures announced by the government.
Foro Penal has reported that dozens of prisoners have been released in recent weeks, but the organization maintains that hundreds of people continue to be detained for political reasons despite the government’s promises and the implementation of the amnesty process.
Families of detainees have continued to demand greater transparency regarding the release process, alleging that many of the promised excarcerations have yet to materialize and calling on authorities to provide clear information about those who remain in custody.

Eight Bodies Found in Ecuador as Authorities Probe Link to Missing Persons Case
Ecuadorian police reported on Wednesday the discovery of eight bodies inside bags in a coastal area of southwestern Ecuador known as a strategic corridor for drug trafficking, as the country continues to grapple with an unprecedented wave of violence.
Authorities are now investigating whether the victims are the same eight people who disappeared on Sunday while traveling to complete a personal errand.
“We have confirmed that there are eight bodies,” said Colonel Galo Muñoz, the police chief for the area, during a press briefing. The bodies were found on the outskirts of the city of Babahoyo.
Interior Minister John Reimberg stated that investigators recovered a note near the bodies suggesting the killings may have been an attack carried out by the criminal organization Los Lobos against Los Choneros, two of Ecuador’s most powerful and violent criminal groups.
According to Muñoz, the bodies were wrapped and transported to a forensic center where specialists will work to establish their identities.
Milagro prosecutor Modesto Freire said the condition of the remains has complicated the identification process.
“The victims’ faces cannot be seen because the bodies are inside bags,” Freire explained.
In a statement posted on social media, Ecuador’s Attorney General’s Office said investigators are collecting evidence to determine whether the remains correspond to the eight individuals reported missing on May 31.
The discovery underscores the ongoing security crisis in Ecuador, where escalating violence linked to organized crime and drug trafficking has become one of the country’s most pressing challenges.

El Niño could intensify global climate risks, warns World Meteorological Organization
Latin American countries, one of the regions in the world most affected by El Niño, must “take extreme precautions” and make use of so-called “climate intelligence” to mitigate the most severe impacts of the phenomenon, the Secretary-General of the World Meteorological Organization (WMO), Celeste Saulo, told EFE on Tuesday.
With a 90% probability, El Niño is expected to return in the second half of this year, and a strong intensity cannot be ruled out.
As a result, the phenomenon could trigger intense rainfall and flooding in some areas, while causing droughts in others, leading to direct impacts on communities and a wide range of economic sectors, including fishing and agriculture.
Saulo said countries in the region have improved their scientific and institutional capacity to monitor and respond to El Niño, as well as to understand how it interacts with other climate variables, including those linked to climate change, in order to better forecast “more or less severe impacts.”
When describing likely consequences in South and Central America, the Argentine scientist first referred to the “Coastal El Niño,” as the phenomenon is known in Peru and Ecuador.
She explained that this event brings increased rainfall and ocean warming, which strongly affects the fishing industry.
She added that northern South America, Central America, and northeastern Brazil are typically exposed to below-normal rainfall or drought conditions. In past extreme episodes, El Niño has even affected the operational capacity of the Panama Canal and created serious water access and management challenges during severe droughts.
In contrast, southeastern South America—including southern Brazil, Paraguay, northern and northeastern Argentina, and Uruguay—can expect above-average rainfall, increasing the risk of flooding, severe storms, and landslides.
Given the potential for fear and misinformation among populations, Saulo urged people to “trust the institutions responsible for meteorological information,” stressing that national meteorological services are the official and authoritative sources in each country.
“These are the ultimate responsible authorities and the voices of expertise,” she emphasized.
The most recent El Niño episode occurred between 2023 and 2024 and was among the five strongest ever recorded, contributing to record global temperatures.
The WMO chief noted that climate models remain uncertain about the intensity of the next El Niño, though more accurate forecasts are expected in the coming weeks.
While climate change has not been proven to increase the frequency or intensity of El Niño events, scientists do know that both can interact and amplify extreme weather impacts, potentially leading to natural disasters.
Although Latin America is often heavily affected, El Niño impacts can also be felt in North America, the Caribbean, central and eastern Africa, parts of Asia, and Australia.
