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.

EU Faces Migration Crisis After 60,000 Migrants Arrive in Spain’s Ceuta Enclave
The arrival of around 60,000 migrants from Morocco to Spain’s Ceuta enclave triggered a major European Union crisis on Friday, after Madrid described the situation as an “attack” on its territorial integrity.
At least 34 people died while attempting to reach the Spanish territory, according to local authorities.
Hundreds of migrants had begun arriving in Ceuta earlier in the week, either by swimming across the border or climbing security fences. Most of those who entered were young men and teenagers.
However, the situation escalated dramatically early Thursday morning, when the number of arrivals surged within a few hours, reaching nearly 60,000 people. According to the Spanish government, the vast majority of them — around 48,000 migrants — had returned to Morocco by Friday evening.
The episode represents one of the most serious migration crises faced by the autonomous city of Ceuta, which has a population of around 84,000 residents, in recent years.
Several European countries responded strongly to the crisis, with Italy announcing the temporary suspension of the Schengen free movement agreement with Spain, a measure supported by Finland and Denmark.
“The temporary suspension of Schengen with Spain is a necessary decision to protect the security of our citizens and defend Europe’s borders,” Italian Foreign Minister Antonio Tajani said in a post on X.
Italy’s Interior Ministry confirmed that the country had tightened controls on maritime and air entry points from Spain, but clarified that the measure would not affect Spanish or European citizens traveling to Italy.
The additional checks will specifically target non-European citizens arriving from Spain, according to the ministry.
The measure will remain in effect for one month starting Saturday, authorities said.
Spain’s Foreign Minister José Manuel Albares responded to the Italian announcement through a statement on X, as European governments continued discussions over the consequences of the migration crisis.

Chuck Schumer Unveils Proposal to Strengthen Oversight of the U.S. Presidency
U.S. Senate Democratic Leader Chuck Schumer on Thursday announced legislation to establish a federal anti-corruption office aimed at strengthening oversight of the executive branch and preventing future presidents from using the White House for personal financial gain.
Schumer said the proposal was prompted by what he described as President Donald Trump’s misuse of the presidencyto benefit his family’s business interests.
“In just 18 months, the Trump family has made more than $4 billion by exploiting the influence of the presidency,” Schumer alleged.
The New York senator also argued that the alleged corruption has had direct economic consequences for American households.
“The same corrupt practices Trump is using to pocket billions of dollars are also forcing Americans to pay, on average, $3,100 more each year because of the rising cost of living,” he said.
The legislation was introduced alongside Democratic Senators Alex Padilla, Jeff Merkley, and Andy Kim.
According to Schumer, the bill has two primary objectives: “First, to return money to the American people. Second, to ensure that no one can ever steal from them again.”
He added that the proposal would create legal mechanisms allowing citizens to seek the recovery of funds allegedly obtained through government corruption.
“The fact that Trump stole money from the American people does not make it his. Americans deserve to get that money back,” Schumer said.
Under the proposed legislation, any U.S. citizen—as well as state attorneys general acting on behalf of their residents—would be authorized to file civil lawsuits to recover funds allegedly acquired through corrupt practices by public officials.
“Our bill would empower any individual, including a state attorney general acting on behalf of the people of that state, to bring legal action to recover money stolen from the public through government corruption,” Schumer said.
The measure is expected to face debate in Congress, where Republicans and Democrats remain deeply divided over executive accountability and the scope of presidential powers.

Trump Administration Urges Latin America to Increase Defense Spending Against Organized Crime
The administration of U.S. President Donald Trump on Wednesday urged Latin American countries to increase investment in defense and security to strengthen the fight against organized crime and drug trafficking networks.
The appeal was made by Elbridge Colby, the U.S. Under Secretary of Defense for Policy, in an article published by Americas Quarterly. Colby argued that governments across the region should assume greater responsibility for protecting their territories from transnational criminal organizations.
“It is essential that our neighbors in the region invest more in their own defense and security. There is no reason why any country, especially those facing significant narco-terrorist threats, should spend so little on defense,” Colby wrote.
The Pentagon official described it as “absurd” that some Latin American nations allocate less than 1% of their Gross Domestic Product (GDP) to defense, although he did not identify the countries. He contrasted that with NATO members in Europe, many of which are increasing defense expenditures to 3.5% of GDP, with an additional 1.5% devoted to security-related investments.
Colby, who participated earlier this month in the Conference of Defense Ministers of the Americas in Cusco, Peru, said there is “a historic opportunity” for the United States and its regional partners to strengthen cooperation against drug trafficking and other transnational threats.
He also defended the proposed Shield of the Americas, a military partnership promoted by the Trump administration to combat organized crime and supported by several conservative governments in the region. The initiative does not include Brazil or Mexico.
In addition, Colby said the administration’s security strategy includes an updated interpretation of the Monroe Doctrine, the long-standing U.S. foreign policy principle that historically viewed Latin America as part of Washington’s sphere of influence.
“Of course, we recognize that the Monroe Doctrine is controversial in many circles. But it is also frequently misunderstood,” he said.
According to Colby, the United States is not seeking “exploitation, subordination or dependence,” but rather a region characterized by greater prosperity, stability and security.
He also stated that Washington is prepared to use “all available resources,” including the U.S. Armed Forces, to combat drug trafficking and irregular migration. Colby highlighted ongoing counternarcotics operations in the Caribbean, despite criticism from human rights organizations that have questioned some missions over allegations of extrajudicial killings in international waters.
