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.

Trump says Jimmy Kimmel show suspension due to poor ratings, not politics

U.S. President Donald Trump dismissed any political motive behind ABC’s suspension of Jimmy Kimmel’s show, stating that the decision is due to “poor viewership ratings” and not a reaction to Kimmel’s comments about the death of Charlie Kirk.

The suspension of Kimmel’s program was announced yesterday and coincided with the comedian’s remarks regarding Kirk’s death and the reactions of prominent Republican figures in the United States.

However, Trump, on his social media platform Truth Social, emphasized that the cancellations of both Kimmel’s and Stephen Colbert’s shows are due to low ratings and limited audience reach.

“Good news for the United States: Jimmy Kimmel’s show, with terrible ratings, has been canceled! Congratulations to ABC for finally having the courage to make this decision. Kimmel has no talent, and his ratings are even worse than Colbert’s, if that’s possible. Now only Jimmy and Seth remain, two failures, on the fake news network NBC. Their ratings are also catastrophic,” Trump wrote.

ABC announced on Wednesday that Jimmy Kimmel’s variety show will be taken off the air “indefinitely,” following threats of legal action from the U.S. government after the host made comments on the political repercussions of conservative activist Charlie Kirk’s assassination.

Padilla and Durbin seek oversight as deportation of Guatemalan minors sparks legal concerns

Democratic Senators Alex Padilla and Dick Durbin have demanded explanations from President Donald Trump’s administration regarding its plans to deport dozens of unaccompanied Guatemalan children in U.S. custody, without allowing them the chance to defend their immigration cases.

The lawmakers said on Wednesday that they have requested oversight hearings in the Senate to compel the White House to respond about the planned deportations, which were initially scheduled for August 31 but remain on hold due to a court order.

According to lawyers representing ten children aged 10 to 16 who filed a lawsuit, the administration violated due process by ignoring ongoing immigration cases and disregarding the special protections granted to minors who crossed the border from Mexico alone.

Under the Trafficking Victims Protection Reauthorization Act (TVPRA), unaccompanied immigrant children in the U.S. generally have the opportunity to appear before an immigration judge before being deported.

Padilla and Durbin’s demand comes after a report by the Government Accountability Project (GAP) alleged that the Trump administration misrepresented the safety of unaccompanied Guatemalan children under its care in order to justify removing them from the country.

The report revealed that at least 30 of the 327 Guatemalan children the administration attempted to deport “show signs” of having been victims of abuse, including death threats, gang violence, human trafficking, or expressed fear of returning to Guatemala.

However, Angie Salazar, director of the Office of Refugee Resettlement (ORR), which maintains custody of the children, testified in court under penalty of perjury that these children showed no evidence of abuse or neglect by a parent or guardian.

Trump criticizes Putin, calls Ukraine war “one of the deadliest conflicts”

U.S. President Donald Trump expressed his disappointment on Thursday with Russian President Vladimir Putin, stating that the war in Ukraine would have been easier to resolve due to the personal relationship they share, but has instead become one of the deadliest conflicts.

During a press conference following a meeting with British Prime Minister Keir Starmer at the official Chequers residence, Trump said he has successfully negotiated the end of seven armed conflicts, though he admitted that the war in Ukraine has been particularly challenging.

The president noted that he initially thought the Russia-Ukraine conflict would be “one of the easiest” to negotiate. However, he cautioned that “you never know in war” and often things “happen in the opposite way than expected.”

When asked why he was disappointed, Trump stated that Putin “is killing a lot of people,” adding that “Russian soldiers are being killed in greater numbers than Ukrainians.”

Prime Minister Starmer emphasized that the United Kingdom continues to work alongside the United States to halt “the killing in Ukraine.” He noted that in recent days, Putin has revealed his true intentions by ordering the most devastating attack since the invasion began in 2022, resulting in more civilian casualties and new violations of NATO airspace.

“President Trump and I have discussed how we can strengthen our defenses, maintain support for Ukraine, and increase international pressure to force Putin to accept a lasting peace agreement,” Starmer said.

The joint statement came on the second day of President Trump’s state visit to the United Kingdom, from the Chequers country residence in Aylesbury, about 60 kilometers from London.
