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.

At Least Eight Dead and 19 Injured in Deadly Bus Crash in Veracruz, Mexico

A tragic bus accident in the eastern state of Veracruz left at least eight people dead and 19 others injured on Wednesday afternoon, according to local authorities.

The vehicle was traveling through the town of Zontecomatlán when it crashed near a ravine, state Civil Protection officials reported late Wednesday night. “Regrettably, the prosecutor’s office has confirmed eight fatalities,” the agency stated in an official release.

Emergency Response and Medical Care Rescue teams worked into the night to assist the survivors. The 19 injured passengers were stabilized at the scene before being transported to hospitals in the nearby municipalities of Chicontepec and Huayacocotla. While the identities of the victims have not yet been released, Mexican press reports indicate the bus was en route from Mexico City to Chicontepec.

A Recurring Issue on Mexican Highways Road accidents involving long-haul passenger buses and freight transport are a frequent occurrence in Mexico. Experts often cite excessive speed, mechanical failure, or driver fatigue as the primary catalysts for these tragedies.

This latest incident follows another major disaster in late November, where 10 people were killed and 20 injured in a similar bus crash in the western state of Michoacán. The recurring nature of these accidents continues to spark national debate regarding the enforcement of stricter safety regulations for commercial transport units.

Jair Bolsonaro Hospitalized for Inguinal Hernia Surgery While Serving Sentence for Attempted Coup

Brazil: Court bans Bolsonaro from running in elections until 2030

Former Brazilian President Jair Bolsonaro, currently serving a 27-year prison sentence for an attempted coup, underwent surgery this Thursday for an inguinal hernia. The procedure took place at the DF Star Hospital in Brasilia, according to his wife, Michelle Bolsonaro.

The 70-year-old former leader left prison on Wednesday for the first time since his incarceration in late November to prepare for the operation. “My love has just gone to the surgical center,” Michelle Bolsonaro posted on Instagram, where she has been documenting her accompaniment during his hospitalization.

Surgical Expectations and Health History Medical professionals treating the far-right ex-president (2019-2022) anticipate the operation will last approximately four hours. His recovery period in the hospital is expected to extend between five and seven days.

Dr. Claudio Birolini explained on Wednesday that while the surgery is standardized, it remains complex due to the patient’s history. Bolsonaro continues to suffer from the long-term effects of a 2018 campaign rally stabbing, an injury that required several major abdominal surgeries in the years following the attack.

“There is no such thing as a simple surgery. However, this is a scheduled and standardized procedure, so we expect it to be carried out without major complications,” Dr. Birolini stated.

Potential Additional Procedures Following the hernia repair, the medical team will evaluate whether Bolsonaro can undergo a second procedure: an anesthetic block of the phrenic nerve. This nerve controls the diaphragm, and the intervention would aim to resolve a chronic case of recurrent hiccups that has plagued the former president for years.

Bolsonaro remains under heavy security at the medical facility as he serves his lengthy sentence related to the events surrounding the January 2023 institutional crisis in Brazil.

Trump Orders Construction of New ‘Golden Fleet’ to Revitalize U.S. Naval Superiority

President Donald Trump issued an executive order this Monday for the immediate construction of two new warships that will bear his name. These vessels will be the pioneers of what he described as the “Golden Fleet,” a future generation of “Trump-class” battleships that he claimed would be “100 times more powerful” than those currently in service.

The announcement took place at his private residence in Mar-a-Lago, Florida. The President indicated that following the initial two ships, the administration aims to commission up to 25 additional vessels. He is scheduled to meet with Florida-based contractors next week to expedite production, criticizing existing defense firms for failing to deliver results efficiently.

This naval expansion is a cornerstone of Trump’s goal to revitalized the American shipbuilding industry and address the strategic gap between the U.S. and competitors like China.

The move comes amid heightened geopolitical tension. Just last week, Trump ordered the seizure of all sanctioned tankers involved with Venezuela’s “ghost fleet” to cripple the country’s crude oil industry. Since December 10, the U.S. military—deployed in the Caribbean under the guise of counter-narcotics operations—has already detained two tankers linked to Venezuelan oil transport.
