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.

Colombia to Send High-Level Delegation to Ecuador to Ease Trade Tensions

Colombia’s Ministry of Foreign Affairs confirmed on Friday that, at the instruction of President Gustavo Petro, a high-level delegation will travel to Ecuador in an effort to normalize bilateral relations, which have deteriorated following the imposition of reciprocal tariffs.

“In line with Colombia’s policy of good neighborliness and the spirit of cooperation and integration that guides its foreign policy,” the Foreign Ministry said in a statement, adding that the delegation will be led by Foreign Minister Rosa Villavicencio and Defense Minister Pedro Sánchez.

“Following instructions from the Presidency of the Republic, and as has been publicly reiterated, the Colombian delegation expects to reaffirm Colombia’s offer of support to the Republic of Ecuador to strengthen control over phenomena stemming from transnational organized crime,” the statement said.

The Foreign Ministry noted that the delegation will attend the meeting with a full willingness to engage in dialogue and to seek concrete solutions to the unilateral measures that have affected the longstanding relationship between the two neighboring countries.

Trade tensions between Ecuador and Colombia escalated on January 21, when Ecuadorian President Daniel Noboaimposed a 30% tariff on Colombian products, citing a lack of cooperation in anti-drug efforts. Colombia responded with similar measures and the suspension of energy exports, while Ecuador increased transportation costs for Colombian crude oil.

Business associations in both countries have warned that the dispute is harming both economies and have called on the governments to resolve their differences through dialogue.

Super Bowl Halftime Show Puts Bad Bunny—and Immigration Politics—Back in the Spotlight

The long-standing argument that sports and politics should not mix may be put to the test on Sunday during the Super Bowl halftime show, which will be headlined by Puerto Rican superstar Bad Bunny, a choice that has sparked backlash from segments of the U.S. right wing.

Just one week after his headline-making appearance at the Grammy Awards—where he sharply criticized the United States’ anti-immigration policies—Bad Bunny will once again take center stage on the global spotlight with his performance at the NFL final in Santa Clara, California.

Beyond the expectations surrounding the show itself, speculation has grown over whether the artist could again use the platform to protest policies associated with the administration of former President Donald Trump, in front of an audience expected to exceed 120 million viewers in the United States alone.

In fact, one of the most popular Super Bowl prop bets this year revolves around whether the Puerto Rican singer will deliver a direct message against ICE (U.S. Immigration and Customs Enforcement), similar to the one he delivered at the Grammys last Sunday.

While few expect Bad Bunny to repeat such a pointed statement, the mere speculation highlights the delicate balance the NFL must manage during the most-watched broadcast of the year.

The world’s most powerful sports league has drawn criticism from the MAGA movement since announcing in September that Bad Bunny would headline a halftime show largely performed in Spanish.

Trump himself declined to attend the matchup between the New England Patriots and the Seattle Seahawks, despite having made history last year as the first sitting U.S. president to attend a Super Bowl. He described the musical lineup—which also includes outspoken critics such as Green Day—as “a terrible choice” that would “sow hatred.” In response, his supporters have organized an alternative event dubbed the “All-American Halftime Show,” featuring like-minded artists such as Kid Rock.

Venezuela Debates Broad Amnesty Law Covering 27 Years of Chavismo

Venezuela’s Parliament began debating on Thursday a sweeping amnesty bill that would cover the 27 years of Chavismo in power, while explicitly excluding serious human rights violations and crimes against humanity.

The proposed legislation, titled the “Amnesty Law for Democratic Coexistence,” was introduced by interim President Delcy Rodríguez, who assumed power following the capture of Nicolás Maduro during a U.S. military operation.

The legislative session was convened for Thursday afternoon, with lawmakers holding an initial discussion focused on the general principles of the bill. This phase precedes a consultation process with civil society, after which the proposal will move to a final debate examining each article individually.

According to a draft of the bill obtained by AFP, the amnesty would apply to individuals accused of crimes such as “treason,” “terrorism,” and “incitement to hatred,” charges that were frequently brought against political prisoners over the past decades. The scope also includes offenses ranging from acts of rebellion to punishments imposed for social media posts or messages sent through private messaging services.

The bill’s explanatory text emphasizes reconciliation, stating that it seeks to move away from “vengeance, retaliation, and hatred” in favor of “opening a path toward reconciliation.”

However, the proposal explicitly excludes from its benefits crimes such as “serious human rights violations, crimes against humanity, war crimes, intentional homicide, corruption, and drug trafficking.”

These exclusions, the text notes, are based on strict compliance with the Venezuelan Constitution, which already prohibits granting amnesties or pardons for such offenses.
