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.

A glacier over Darwin's mountain range is seen during a journey through the Beagle Channel in the Magallanes region, the southernmost of Chile, on September 23, 2022. - There is a place at the end of the world, in the southernmost point of Chile, where pristine forests hide tiny systems in their depths that already give early warning of the global climate change that the planet is suffering. 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.

Football Fan Killed in Clashes After Colombian League Match

Fans of Cúcuta Deportivo and their traditional rivals Atlético Bucaramanga clashed outside the stadium following their local league match on Tuesday, leaving one supporter dead and several others injured.

The deceased fan was stabbed, according to a senior police official in Cúcuta who confirmed the cause of death in a video statement. Local media reported that the victim was a supporter of the visiting team, Atlético Bucaramanga.

The match ended in a 2-2 draw. Authorities had banned the entry of Atlético Bucaramanga’s organized supporters into the stadium in an effort to prevent disturbances.

Despite the restrictions, violence broke out in the surrounding areas after the game. Among the injured were three police officers, an institutional source told AFP.

The incident adds to a series of recent violent episodes linked to Colombian football. The most recent occurred in December, when supporters of Atlético Nacional and Independiente Medellín clashed in the stands and on the pitch, leaving 59 people injured.

Missing Spanish Sailor Rescued After 11 Days Adrift in Mediterranean

The man had departed from the port of Gandía, on Spain’s eastern coast, with the intention of reaching the southern Spanish town of Guardamar del Segura, a journey of about 150 kilometers, a spokesperson for Spain’s maritime rescue service told AFP.

Search boats and aircraft were deployed on January 17, but the operation was called off on January 22 after efforts proved unsuccessful. Alerts were then issued to vessels navigating the area in case they spotted any signs of the missing sailor.

As hopes were fading, a surveillance aircraft from the European Union’s border agency Frontex spotted the sailboat on Tuesday, along with a person signaling for help, approximately 53 nautical miles northeast of Bejaia, Algeria.

A nearby vessel, the Singapore-flagged bulk carrier Thor Confidence, carried out the rescue and is expected to bring the man to an end to his ordeal when it arrives on Thursday in the southern Spanish port city of Algeciras.

Maritime rescue services shared images on social media showing a small white sailboat drifting at sea and secured alongside the much larger ship.

It remains unclear how the sailboat ended up hundreds of kilometers off its intended route or how the man managed to survive for so long alone in open waters.

Rubio Says U.S. Could Participate in Follow-Up Russia-Ukraine Talks

The United States could join a new round of talks this week aimed at ending Russia’s invasion of Ukraine, Secretary of State Marco Rubio said on Tuesday.

Teams from Kyiv and Moscow met last Friday and Saturday in Abu Dhabi in their first publicly acknowledged direct negotiations to discuss the peace initiative promoted by former U.S. President Donald Trump.

“They are going to hold follow-up talks again this week,” Rubio told the Senate Foreign Relations Committee. “There could be U.S. participation.”

However, Rubio suggested that Washington’s role may be more limited than during last week’s discussions, which included Steve Witkoff, the president’s special envoy, and Jared Kushner, Trump’s son-in-law.

The secretary of state indicated that progress may have already been made on security guarantees for Ukraine, one of Kyiv’s key demands in any agreement with Moscow after nearly four years of Russian invasion.

“There is one remaining issue that everyone is familiar with, and that is the territorial claim over Donetsk,” Rubio said, referring to the eastern Ukrainian region that Russia wants Ukraine to cede.

“I know that active efforts are underway to see whether the positions of both sides on this issue can be reconciled. It remains a bridge we have not yet crossed,” he added during the hearing.

Rubio acknowledged that the territorial question would be particularly difficult for Ukraine to resolve.
