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.

Ukraine declares nationwide energy emergency amid russian attacks and extreme cold
The Ukrainian government on Wednesday declared a nationwide energy state of emergency amid continued Russian military attacks and extreme winter weather, with nighttime temperatures dropping as low as minus 18 degrees Celsius.
“The consequences of Russian attacks and worsening weather conditions are severe (…) Overall, a state of emergency will be declared for Ukraine’s energy sector,” Ukrainian President Volodymyr Zelensky said in a statement posted on social media following a meeting with senior officials.
Zelensky announced the creation of a “permanent coordination headquarters” to manage the crisis in the capital, Kyiv, and tasked former defence minister and current energy chief Denys Shmyhal with overseeing support efforts for affected individuals and communities, including addressing power outages, heating shortages and other “practical issues.”
“There are many problems that require urgent solutions,” the president said, noting that repair crews, energy companies, municipal services and the State Emergency Service are working “around the clock” to restore electricity supplies. Kyiv has been particularly affected after Russian strikes last Friday disabled key parts of the power grid, as daytime temperatures hover around minus 12 degrees Celsius and plunge to minus 18 at night.
Zelensky added that public authorities will “maximize efforts with partners to obtain the necessary equipment and additional support,” while the government will ensure “maximum deregulation of all processes” to speed up the connection of backup power equipment to the grid. He also confirmed that work is underway to significantly increase electricity imports into Ukraine.
The Ukrainian leader further instructed his Cabinet to review curfew regulations in light of the extreme cold, arguing that citizens must have the greatest possible access to assistance centers, while businesses should be given flexibility to plan their operations according to the state of the energy system.

France joins Denmark’s ‘Operation Arctic Resistance’ in Greenland amid U.S. tensions
French President Emmanuel Macron confirmed in the early hours of Thursday (Wednesday afternoon in El Salvador) that France will take part in “Operation Arctic Resistance,” after Denmark announced it would expand its military presence in Greenland amid rising tensions with the United States over Washington’s stated ambitions regarding the semi-autonomous territory.
“At Denmark’s request, I have decided that France will participate in the joint exercises organized by Denmark in Greenland, ‘Operation Arctic Resistance,’” Macron said in a brief message posted on social media at 5:18 p.m.
The French president added that “the first French military elements are already on their way, with others to follow,” though he did not specify the number of troops being deployed or the scale of France’s planned contribution.
The governments of Sweden, Norway and Germany have also confirmed the deployment of military contingents to Greenland. Germany’s armed forces will send a 13-member reconnaissance team to the Greenlandic capital, Nuuk, to take part in a mission scheduled to run from Thursday through Saturday, according to the German Ministry of Defence.
Denmark’s announcement came shortly before a Danish delegation met at the White House with U.S. Vice President JD Vance and Secretary of State Marco Rubio to discuss Washington’s plans regarding Greenland. Copenhagen said the military activities would be carried out “in close cooperation with NATO allies.”

Iran closes airspace amid U.S. threats and deadly nationwide protests
Iranian authorities closed the country’s airspace in the early hours of Thursday, according to data from flight-tracking website FlightRadar24, amid growing threats of a possible U.S. attack as protests across the country continue and have reportedly left thousands dead.
According to FlightRadar24, the Iranian government suspended all flights to and from the country, except for international flights that have received special authorization. The notice was initially issued for a duration of just over two hours.
The move comes after U.S. President Donald Trump in recent days threatened to strike Iran if its security forces failed to halt the deaths linked to weeks-long protests that began in Tehran and later spread to other Iranian cities. Despite the threats, the White House said diplomacy remains Trump’s preferred option.
Speaking from the Oval Office on Wednesday, Trump claimed that “the deaths in Iran have stopped” and said there would be no executions of protesters following his warnings to Tehran. He added that his administration would seek to verify those claims.
“I’ve been told the deaths in Iran are stopping. They’ve stopped, and that there are no plans for executions,” Trump told reporters, cautioning that the United States would be “very upset” if those assurances proved to be untrue.
The statements contrast with reports from rights groups. The Norway-based NGO Iran Human Rights (IHRNGO) said on Wednesday that more than 3,400 people have been killed since the protests erupted. Meanwhile, Kurdish-Iranian rights group Hengaw reported this week that a 26-year-old Iranian man, Erfan Soltani, was facing execution as of Wednesday.
