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.

Pilot killed and two Pennsylvania state troopers injured in mid-air collision

A pilot was killed and two Pennsylvania state police officers were injured when a Cessna 150 airplane collided with the helicopter they were traveling in during a routine training exercise at a regional airport in the state.

Pennsylvania Governor Josh Shapiro identified the officers as Corporal Bryce Corman and Trooper Jason Mills, members of the Pennsylvania State Police aviation unit. Both are expected to recover from their injuries, according to ABC.

The county coroner’s office identified the pilot as 57-year-old Paul Sokoloski.

George Bivens, acting commissioner of the Pennsylvania State Police, said the collision occurred at around 6:50 p.m. Wednesday. The helicopter was flying several feet above a grassy area near a runway at Carlisle Regional Airport when the small plane approached from behind.

According to investigators, the Cessna suddenly veered to the right moments before the collision, striking the helicopter’s tail rotor before also hitting its main rotor.

The airplane crashed a short distance away and broke into several pieces, while the helicopter lost its tail and other components before crashing on its side.

Police said Corporal Corman opened a window and helped Trooper Mills escape from the helicopter because they feared the aircraft could catch fire.

The Federal Aviation Administration and the National Transportation Safety Board are investigating the circumstances surrounding the crash.

Argentina’s Milei Links Low Birth Rates to Abortion and Feminism

Argentine President Javier Milei on Thursday blamed feminism and the legalization of abortion for the country’s declining birth rate, arguing that the demographic trend is creating economic and pension-system challenges.

“We are paying a very high price for the madness of the green scarves,” Milei said during a speech at the Council of the Americas in Buenos Aires, referring to the symbol associated with the feminist movement and the campaign for legal abortion in Argentina.

According to Milei, Argentina is failing to reach the population growth and birth rates needed to maintain demographic replacement.

He also linked the decline in births to future challenges for the country’s pension system and workforce.

“That passion for killing children in the mother’s womb is costing us in terms of growth and pensions. It is also costing us in terms of human capital,” the president said.

Milei has consistently opposed abortion, which has been legal in Argentina since 2020. The law was considered a major victory for the feminist movement across Latin America at the time of its approval.

In February 2024, lawmakers from Milei’s La Libertad Avanza (LLA) party introduced a bill seeking to repeal voluntary abortion legislation.

Under Argentina’s current law, abortion is legal, safe and free of charge up to the 14th week of pregnancy. After that period, it is permitted when the pregnancy poses a risk to the woman’s life or health, or when it resulted from rape.

Milei has repeatedly criticized abortion

The Argentine president has also criticized abortion and feminism in international forums. During his speech at the World Economic Forum in Davos in January 2024, he attacked the feminist movement and denounced what he described as the “bloody agenda of abortion.”

His latest comments come amid growing concerns over Argentina’s demographic outlook and the potential long-term effects of declining birth rates on economic growth, the labor force and social security.

Virginia Police Arrest Salvadoran Man in Great Falls Woman’s Killing

Alexis Antonio Cedillos-Campos, 19, identified by federal officials as an undocumented immigrant from El Salvador, was arrested in connection with the death of Carmen Lizet Puch, 42, who was found dead Monday, the Fairfax County Police Department said.

Authorities said Cedillos-Campos and Puch were coworkers and were also involved in an “intimate relationship.”

“Our victim suffered numerous stab wounds in a truly brutal and indescribable manner,” Police Chief Kevin Davis said during a news conference Wednesday.

Investigators said surveillance video showed Cedillos-Campos at the restaurant where he and Puch worked, allegedly taking a fixed-blade knife, a pair of black latex gloves and a bottle of water before leaving.

“He left with the intent to harm and kill the victim,” Davis said.

Cedillos-Campos was arrested Wednesday morning in Maryland and confessed to the killing, according to Davis. He is awaiting extradition to Virginia. Authorities have not said whether he has an attorney representing him.

The Department of Homeland Security said Cedillos-Campos had previously been arrested by U.S. Customs and Border Protection in 2024 after allegedly crossing the U.S.-Mexico border illegally near El Paso, Texas.
