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.

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.

China calls for dialogue amid rising Iran-Israel conflict
The Chinese government emphasized on Monday the importance of “creating the conditions to return to the proper path of dialogue” between Iran and Israel, which have exchanged attacks in recent days resulting in more than 20 Israeli and over 220 Iranian deaths.
Chinese Foreign Ministry spokesperson Guo Jiakun expressed deep concern at a press conference over the Israeli attacks on Iran and the “sudden escalation” of the military conflict.
Guo called on all parties to “take immediate measures to ease tensions and prevent the region from descending into further turmoil,” stating that “force cannot bring lasting peace.”
“If the conflict between Israel and Iran continues to intensify or even expand, the countries of the Middle East will be the first to suffer the consequences,” he added, while noting that China “will continue to maintain communication with the relevant parties, promoting peace and dialogue.”
Chinese Foreign Minister Wang Yi spoke last Saturday with his Iranian and Israeli counterparts to condemn the Israeli airstrike on Iranian territory, which he described as a “violation of international law” with the potential to trigger “disastrous” consequences.
In both calls, Wang reiterated China’s rejection of the use of force, defended diplomacy as the only solution to the Iranian nuclear dispute, and offered China’s mediation to prevent further destabilization in the Middle East.

Suspect arrested in killing of Minnesota legislator and husband, governor Says
Minnesota Governor Tim Walz announced on Sunday the arrest of Vance Luther Boelter, 57, the main suspect in the killing of Democratic legislator Melissa Hortman and her husband in a Brooklyn Park suburb on Friday night.
Boelter, who also reportedly shot State Senator John Hoffman and his wife early Saturday morning, was apprehended in Sibley County following an intensive manhunt involving hundreds of law enforcement officers.
In a public statement, Governor Walz condemned Boelter’s “unthinkable actions,” which resulted in the death of a woman who “shaped the core of who we are as a state.”
“We cannot become numb to this. We are a deeply divided nation,” Walz said in a statement posted on his X account.
“We move forward not with hatred or violence, but with humility, grace, and civility,” he added.
Expressing solidarity with the victims’ families, Walz said the entire state of Minnesota is in mourning. He also thanked law enforcement for their bravery and professionalism: “They have saved lives,” he emphasized.
“As we heal, we will not let fear win,” Walz concluded. “We must honor Melissa by moving forward with understanding, service, and above all, humanity.”
Throughout Sunday, police and sheriff units searched a rural area in Minnesota for Vance Luther Boelter, a security company director and preacher who, according to Governor Walz, acted out of politically motivated violence.

40,000 tourists stranded in Israel amid airspace shutdown over Iran conflict
Approximately 40,000 tourists are stranded in Israel following the closure of the country’s airspace amid escalating hostilities with Iran, the Israeli Ministry of Tourism reported on Monday.
The ministry has set up a virtual office to provide information via email (virtual@goisrael.gov.il) and phone (+972-53-583-5808), as well as a Facebook page called Israel Virtual Tourist Office.
Israeli Tourism Minister Haim Katz is in contact with hotels and accommodations across the country to offer support to tourists in need, the ministry added.
Many stranded travelers are considering crossing overland into Jordan or Egypt to seek flights from those countries. The Israel Airports Authority reminded the public that land border crossings remain open.
Three German tourists stranded in Jerusalem told EFE today that they have not received any assistance from their country’s embassy in Israel, and their primary option currently is to cross into Jordan to catch a flight from there.
Since early Friday morning, Israel launched operations against Iran, targeting military personnel and infrastructure, including energy and nuclear facilities, as well as numerous residential areas in Tehran.
In response, Iran has fired hundreds of ballistic missiles at Israel, some of which have struck various locations across the country, leaving at least 24 dead so far, according to Israeli authorities.
Iranian health officials report at least 224 deaths, mostly civilians, including at least 17 senior military officials—nine from the Revolutionary Guard—and more than a dozen nuclear scientists.
The Israeli military has warned that many more “targets” remain, while Iran’s Revolutionary Guard declared on Monday that it will continue missile attacks against Israel until its “destruction.”
