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.

U.S. Senate Rejects Budget, Bringing Government Closer to Shutdown Amid DHS Dispute

The U.S. Senate voted on Thursday against a budget proposal in a move aimed at pressuring changes at the Department of Homeland Security (DHS), following the killing of two civilians during a deployment of immigration agents in Minneapolis.

All Senate Democrats and seven Republican lawmakers voted against the bill, which requires 60 votes to advance, pushing the country closer to a partial government shutdown that would cut funding for several agencies, including the Pentagon and the Department of Health.

The rejection came as Senate leaders and the White House continue negotiations on a separate funding package for DHS that would allow reforms to the agency. Proposed measures include banning Immigration and Customs Enforcement (ICE) agents from wearing face coverings and requiring them to use body-worn cameras during operations.

The vote took place just hours after President Donald Trump said he was “close” to reaching an agreement with Democrats and did not believe the federal government would face another shutdown, following last year’s record stoppage.

“I don’t think the Democrats want a shutdown either, so we’ll work in a bipartisan way to avoid it. Hopefully, there will be no government shutdown. We’re working on that right now,” Trump said during a Cabinet meeting at the White House.

Trump Says Putin Agreed to One-Week Halt in Attacks on Ukraine Amid Extreme Cold

U.S. President Donald Trump said on Thursday that he secured a commitment from Russian President Vladimir Putinto halt attacks against Ukraine for one week, citing extreme weather conditions affecting the region.

“Because of the extreme cold (…) I personally asked Putin not to attack Kyiv or other cities and towns for a week. And he agreed. He was very pleasant,” Trump said during a Cabinet meeting broadcast by the White House.

Trump acknowledged that several advisers had questioned the decision to make the call.
“A lot of people told me not to waste the call because they wouldn’t agree. And he accepted. And we’re very happy they did, because they don’t need missiles hitting their towns and cities,” the president said.

According to Trump, Ukrainian authorities reacted with surprise to the announcement but welcomed the possibility of a temporary ceasefire.
“It’s extraordinarily cold, record cold (…) They say they’ve never experienced cold like this,” he added.

Ukrainian President Volodymyr Zelensky later commented on the announcement, expressing hope that the agreement would be honored.

Storm Kristin Kills Five in Portugal, Leaves Nearly 500,000 Without Power

Storm Kristin, which battered Portugal with heavy rain and strong winds early Wednesday, has left at least five people dead, while nearly half a million residents remained without electricity as of Thursday, according to updated figures from authorities.

The revised death toll was confirmed to AFP by a spokesperson for the National Emergency and Civil Protection Authority (ANPEC). On Wednesday, the agency had reported four fatalities.

Meanwhile, E-Redes, the country’s electricity distribution network operator, said that around 450,000 customers were still without power, particularly in central Portugal.

Emergency services responded to approximately 1,500 incidents between midnight and 8:00 a.m. local time on Wednesday, as the storm caused widespread disruptions.

The Portuguese government described Kristin as an “extreme weather event” that inflicted significant damage across several regions of the country. At the height of the storm, as many as 850,000 households and institutions lost electricity during the early hours of Wednesday.

Several municipalities ordered the closure of schools, many of which remained shut on Thursday due to ongoing adverse conditions.

Ricardo Costa, regional deputy commander of the Leiria Fire Brigade, said residents continue to seek assistance as rainfall persists.
“Even though the rain is not extremely intense, it is causing extensive damage to homes,” he noted.

In Figueira da Foz, a coastal city in central Portugal, strong winds toppled a giant Ferris wheel, underscoring the severity of the storm.
