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.

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.

Man arrested after deliberately driving into seven children in Osaka
Japanese police arrested a man on Thursday after he rammed his car into a group of seven schoolchildren in an apparent deliberate attack in the city of Osaka.
The children, who were on their way home from school, sustained injuries and were taken to the hospital. All seven remained conscious, according to local authorities.
An Osaka police officer, speaking on condition of anonymity, said the suspect is a 28-year-old man from Tokyo. The officer shared statements the man made after his arrest: “I was fed up with everything, so I decided to kill people by driving into several elementary school children,” the suspect reportedly said.
The man has been arrested on suspicion of attempted murder.
The injured children, aged between seven and eight, included a seven-year-old girl who suffered a fractured jaw. The six other children—all boys—suffered minor injuries such as bruises and scratches and were undergoing medical evaluation.
Witnesses described the car as “zigzagging” before hitting the children. One witness told Nippon TV that a girl was “covered in blood” and the others appeared to have scratches.
Another witness said the driver, who was wearing a face mask, looked to be in shock when school staff pulled him from the vehicle.
Violent crimes are rare in Japan, though serious incidents do occur from time to time. In 2008, Tomohiro Kato drove a two-ton truck into pedestrians in Tokyo’s Akihabara district, then fatally stabbed several victims. Seven people were killed in that attack.

Clashes erupt during may day protests across France amid calls for better wages
May Day protests in France were marked by a heavy police presence and clashes between demonstrators and law enforcement in several cities.
In Paris, Lyon, and Nantes, thousands took to the streets to demand better wages, fairer working conditions, and to voice their dissatisfaction with President Emmanuel Macron’s government.
While the majority of the demonstrations remained peaceful, isolated confrontations broke out in some areas. Protesters threw objects at the police, prompting the use of tear gas and resulting in several arrests.
Videos showing police crackdowns circulated widely on social media, drawing criticism from labor unions and human rights advocates, who denounced the authorities’ response to the protests.

Kristi Noem credits Trump for mass migrant deportations by mexican president
U.S. Secretary of Homeland Security Kristi Noem claimed that Mexican President Claudia Sheinbaum has deported “more than half a million” migrants due to pressure from former President Donald Trump.
During a cabinet meeting highlighting the “achievements” of Trump’s administration in its first 100 days, Noem asserted that under the Republican leader’s influence, “Mexico has finally come to the table” to negotiate on migration and fentanyl trafficking.
“The president of Mexico told me she has returned just over half a million people before they reached our border,” Noem stated, criticizing media reports that suggest the Biden administration deported more migrants than Trump’s.
“I wish those deportations were counted,” Noem added, “because those people never made it to our border—she sent them back because you made her.” She went on to thank Trump: “They never made it here because they got the message—because you were so aggressive.”
Noem has made controversial claims about Sheinbaum in the past, prompting the Mexican leader to refute them.
On April 1, Sheinbaum responded to one such statement by declaring, “The president answers to only one authority, and that is the people of Mexico,” after Noem said on Fox News that she gave Sheinbaum “a list of things Trump would like to see” and that Mexico’s actions would determine whether Trump granted tariff relief.
