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.

Two Police Officers Shot During Road Clearance Operation in Eastern Bolivia

At least two police officers were wounded by gunfire on Saturday during an operation to clear roadblocks in Bolivia’s eastern Santa Cruz region, which has remained partially cut off for 24 days amid protests demanding the resignation of President Rodrigo Paz.

The joint operation involving the Police and the Armed Forces began at 6:00 a.m. local time near the town of San Julián, approximately 117 kilometers northeast of Santa Cruz city. The effort focused on reopening an alternative highway linking the region with Beni and western Bolivia.

According to Santa Cruz Police Commander David Gómez, protesters initially responded aggressively to the security operation.

“Local groups organized themselves and began attacking us brutally with firecrackers, stones, and other objects,” Gómez told reporters. “We used chemical agents in an attempt to disperse the crowd, which was behaving aggressively.”

Authorities initially succeeded in reopening the roadway, allowing vehicles to pass through. However, protesters later regrouped and engaged in renewed clashes with police forces that lasted for more than four hours.

During the confrontation, gunshots were heard, forcing both police and military personnel to withdraw from the area.

Gómez reported that one officer suffered a gunshot wound to the head, while another was struck in the right thigh. Both officers were evacuated for medical treatment.

The police commander stated that demonstrators not only carried out physical attacks against officers but also used firearms during the confrontation, prompting authorities to order a tactical retreat.

The incident marks a significant escalation in tensions surrounding the ongoing protests in Santa Cruz, where demonstrators have maintained roadblocks for more than three weeks as part of their campaign against the government.

U.S. to invest $700 million in coal plants and mines under Trump initiative

U.S. President Donald Trump announced on Thursday a $700 million funding package aimed at supporting the American coal industry, marking the latest step in his administration’s efforts to boost the use of the fossil fuel.

According to Trump, the funding will be used to keep 14 coal-fired power plants operating across ten states, maintain 42 coal mines, and support the construction of two new power plants and an export terminal.

The president said the initiative will be financed through the Defense Production Act, a law enacted in 1950 that grants emergency powers to the president to support and direct domestic industries considered critical to national interests.

Since returning to the White House last year, Trump has pursued policies designed to expand domestic energy production and roll back a number of environmental regulations. He has also repeatedly questioned the scientific consensus regarding human-caused climate change.

Coal remains the most carbon-intensive fossil fuel and is the largest source of greenhouse gas emissions among major energy sources, making it a central focus of debates over climate policy and energy security.

U.S. Energy Secretary Chris Wright defended the initiative, describing coal as a critical resource for both electricity generation and industrial production.

The announcement comes as global energy markets continue to evolve. According to an analysis by the Global Energy Monitor, the world added and commissioned more coal-fired power capacity in 2025, although overall coal consumption declined. The report also found that the United States was the only major economy to record a significant increase in coal-fired power generation during that period.

The new funding package underscores the administration’s commitment to supporting traditional energy industries while debate continues over the balance between energy security, economic growth and environmental objectives.

Four decapitated bodies found in abandoned vehicle near Guerrero state Congress

Police in Mexico have found four decapitated bodies inside an abandoned vehicle parked near the state Congress building in Guerrero, authorities confirmed on Thursday.

The southern state of Guerrero, home to the resort city of Acapulco, has long been affected by violent clashes between criminal organizations competing for control of drug trafficking routes.

According to prosecutors cited by AFP, the bodies were wrapped in black plastic bags and left inside a car parked at one of the rear entrances of the legislative building in the state capital, Chilpancingo.

Authorities say the region has seen intensified conflict between rival drug trafficking groups, including the Sierra Cartel and Los Ardillos, a criminal organization that Indigenous communities have accused of carrying out attacks in the mountainous, impoverished areas of the state.

The ongoing violence highlights the persistent security crisis in Guerrero, where organized crime continues to exert significant influence over large parts of the territory.
