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.

United Nations Coordinates Relief Efforts as Venezuela Death Toll Rises After Twin Quakes
United Nations Secretary-General António Guterres on Thursday expressed his condolences to the people of Venezuela following the two devastating earthquakes that struck the country and highlighted the ongoing coordination between UN humanitarian teams and interim President Delcy Rodríguez.
Speaking during the UN’s daily press briefing, spokesperson Stéphane Dujarric said Guterres was deeply saddened by the loss of life and widespread destruction caused by the disaster.
“The Secretary-General is deeply distressed by the loss of life and the widespread devastation caused by the earthquakes that struck Venezuela yesterday. He extends his heartfelt condolences to the families of the victims and wishes a speedy recovery to those injured,” Dujarric stated.
Venezuela was struck on Wednesday by two powerful earthquakes measuring 7.2 and 7.5 in magnitude. According to official figures, the disaster has left at least 164 people dead and 971 others injured.
Dujarric noted that preliminary reports indicate significant damage across several states, including the capital, Caracas. Numerous casualties have been reported, while other individuals remain trapped beneath collapsed structures or are still missing.
“Critical infrastructure has been damaged and essential services have been disrupted,” the spokesperson said.
The United Nations confirmed that its humanitarian team remains in close contact with interim President Delcy Rodríguez and other relevant authorities as emergency operations continue.
To support relief efforts, the UN has established a coordination center in Caracas and is assisting local authorities to ensure that humanitarian aid reaches affected communities as quickly and efficiently as possible.
Guterres also welcomed the expressions of solidarity and offers of assistance from countries around the world that responded following news of the disaster, underscoring the importance of international cooperation in addressing the humanitarian emergency.

OAS Secretary General Pledges Regional Assistance Following Venezuela Quake Disaster
The Secretary General of the Organization of American States (OAS), Albert Ramdin, said on Thursday that the “hemispheric community” stands ready to provide “full support” to Venezuela and its people following the powerful earthquakes that struck the country overnight, leaving at least 164 people dead and nearly 1,000 injured.
Speaking at the conclusion of the OAS General Assembly, Ramdin expressed solidarity not only with Venezuela but also with Colombia, Curaçao and Aruba, where the tremors were also felt.
“Above all, our thoughts are with these peoples,” he said during his remarks.
Ramdin noted that while many details about the disaster are still emerging, countries across the hemisphere are prepared to assist Venezuela as it responds to the crisis.
“Much remains unknown at this stage, but the hemispheric community will be ready to support the people of Venezuela during this very difficult time,” he stated, reiterating the organization’s commitment to helping those affected.
According to updated information released by the Venezuelan government, the powerful earthquakes have been followed by at least 30 aftershocks. Authorities have also reported extensive structural damage, including numerous building collapses in La Guaira, the area considered hardest hit by the disaster.
Rescue efforts are currently focused on La Guaira, where emergency teams continue searching for survivors trapped beneath the rubble as officials assess the full extent of the damage.

Bill Gates Says Jeffrey Epstein Made “Veiled” Threats Over Extramarital Affairs
Microsoft co-founder Bill Gates told members of the U.S. Congress that he received “veiled” threats from convicted sex offender Jeffrey Epstein related to his extramarital affairs, according to a transcript of his testimony released Tuesday.
Gates testified behind closed doors on June 10 before the House Oversight Committee regarding his relationship with the American financier, who died in prison in 2019 while awaiting trial on sex trafficking-related charges. Epstein had previously been convicted in 2008 for soliciting prostitution from a minor.
According to the transcript released by the committee, Gates said Epstein appeared to want to use his knowledge of Gates’ personal relationships as leverage to keep him within his circle at a time when Gates was already distancing himself.
“I was not blackmailed, but reading these emails, it seems like Mr. Epstein’s ideas were moving in that direction,” Gates said, referring to documents from the Epstein case released by the Justice Department in January.
Gates added that Epstein never sent him anything he would personally classify as blackmail. However, he said the content of certain draft emails suggested Epstein was “rehearsing” how he, or someone he instructed, might attempt to pressure him.
“He was, in a way, practicing how he himself, or someone he directed, could choose to blackmail me, but none of those messages were ever sent to me,” Gates told lawmakers.
The 70-year-old billionaire had previously stated that he was unaware of Epstein’s criminal behavior and said he had never been involved in harming anyone.
In February, Gates told The Wall Street Journal that his association with Epstein was a serious mistake. He also acknowledged having extramarital relationships, while denying any involvement in Epstein’s criminal activities.
Gates said his relationship with Epstein began in 2011, three years after Epstein’s conviction, and acknowledged that he was aware of Epstein’s legal troubles at the time.
However, Gates said he was told that Epstein had the ability to raise billions of dollars for global health initiatives, an area in which Gates had significant involvement.
“When I met him, I knew he had been convicted,” Gates told lawmakers. “I knew it was of a sexual nature, but I didn’t try to learn more, although I probably should have.”
