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.

U.S. Proposes Higher Citizenship Fees and Limits on Immigration Fee Waivers
The U.S. Department of Homeland Security (DHS) has proposed increasing fees related to citizenship applications, while also seeking changes to programs that reduce or waive immigration-related costs for certain applicants.
The proposal would eliminate fee waivers and reduced-fee programs for immigrants whose household incomes are at or below 400% of the federal poverty level.
However, the changes would not take effect immediately. Before receiving final approval, the proposal must go through a 60-day public comment period, allowing individuals and organizations to submit feedback.
DHS justified the proposed increases by stating that the goal is to fully cover the costs associated with processing citizenship and naturalization applications.
“Although the Department of Homeland Security has historically limited form fees to promote naturalization, the agency no longer considers that these applications should have lower costs at the expense of other immigration benefits,” the department said in the proposal document.
If approved, the reform would modify the current immigration fee structure and could impact thousands of applicants who rely on financial assistance programs to complete their citizenship process.
U.S. authorities said the measure is part of a broader review of immigration service fees and the mechanisms used to fund the administration of these programs.

Cristiano Ronaldo Makes History as First Player to Score in Six World Cups
Cristiano Ronaldo made football history on Tuesday by becoming the first player ever to score in six different editions of the FIFA World Cup.
The Portuguese forward opened the scoring in Portugal’s Group K match against Uzbekistan in Houston. Just six minutes into the game, Ronaldo found the back of the net with a right-footed strike from inside the box, sending the Portuguese fans into celebration.
The “Commander” sparked excitement throughout the stadium with his iconic celebration, as supporters joined in with his famous “Siuuu!” chant to honor another milestone in the career of one of football’s greatest stars.
At 41 years old, Ronaldo has now scored in Germany 2006, South Africa 2010, Brazil 2014, Russia 2018, Qatar 2022, and North America 2026. With his two goals in this tournament, he has surpassed Lionel Messi’s record, as the Argentine has scored in every World Cup he played except South Africa 2010.
The Portuguese captain has also reached nine World Cup goals, matching Eusébio as Portugal’s all-time top scorer in the history of the tournament.
Ronaldo’s achievement came just one day after Messi also made history by becoming the outright leading scorer in World Cup history, reaching 18 goals after scoring twice in Argentina’s 2-0 victory over Austria.
With his appearance at the 2026 World Cup, Cristiano Ronaldo has also extended another remarkable record by becoming the first player to participate in six consecutive editions of the tournament, further cementing his legacy as one of the most influential players in football history.

Mbappé Ties Klose on All-Time World Cup Scoring List After Brace Against Iraq
Kylian Mbappé moved another step closer to World Cup history on Monday, scoring twice against Iraq to reach 16 career goals in the tournament and draw level with German legend Miroslav Klose on the all-time scoring chart.
The French forward found the net in the 14th and 54th minutes of France’s Group I clash in Philadelphia, registering his second consecutive brace of the 2026 FIFA World Cup.
Mbappé’s achievement came on the same day that Argentina captain Lionel Messi set a new all-time World Cup scoring record. The Argentine star scored twice against Austria to raise his career total to 18 goals, surpassing the previous mark of 16 held by Klose.
Klose established his record on July 8, 2014, during Germany’s historic 7-1 victory over Brazil in the World Cup semifinals in Belo Horizonte.
Before facing Iraq, Mbappé was tied with German striker Gerd Müller on 14 World Cup goals. His first goal of the match lifted him to 15, drawing level with Brazilian great Ronaldo Nazário.
The second strike moved the Real Madrid forward to 16 goals, allowing him to surpass Ronaldo, match Klose’s tally, and position himself just two goals behind Messi in the race for World Cup immortality.
The match also marked a personal milestone for Mbappé, as he made his 100th appearance for the French national team.
At 27 years old, the French superstar remains firmly in pursuit of Messi’s newly established record and continues to strengthen his legacy as one of the most prolific scorers in World Cup history.
