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.

Nine People Killed in Two Armed Attacks in Manabí, Ecuador

At least nine people were killed Monday in two nearly simultaneous armed attacks in the province of Manabí, located on Ecuador’s Pacific coast, one of the areas hardest hit by violence in the country, according to the National Police.

The first attack left seven people dead and took place in Camarones, a rural area of the Jama canton. The second occurred in the sector known as La Y, in the seaside town of Canoa, part of the San Vicente canton, where two people were killed.

According to preliminary reports, both incidents occurred early Monday morning when armed men intercepted the victims. Authorities said the motives behind the attacks remain under investigation.

The assault in Camarones happened around 1:15 a.m. local time, when a group of armed individuals stormed a ranch in the area. The victims have not yet been officially identified.

About 15 minutes later, in Canoa, two men traveling in a motorized taxi were intercepted by armed suspects riding motorcycles and shot. One of the victims was identified as a 28-year-old passenger, while the identity of the driver has not yet been confirmed.

The attacks occurred just days after another multiple homicide on February 12 at a ranch in San Juan de las Cucarachas, a rural area of the Santa Ana canton in Manabí, which left six people dead.

Manabí has been experiencing escalating insecurity linked to disputes among organized crime groups, including drug trafficking networks and territorial control conflicts. In response, the government has maintained a state of emergency in the province since August to address the surge in violence attributed to these criminal organizations.

Over 40 Million Affected by Major Snowstorm in Northeastern U.S.

More than 40 million people across the northeastern United States are facing a new major snowstorm this Monday, including residents of New York City, where local authorities have shut down roads to traffic.

The storm triggered widespread flight cancellations early in the morning and caused power outages affecting thousands of homes and businesses throughout the region.

New York City Mayor Zohran Mamdani banned non-essential vehicle travel at least until noon and ordered the closure of public schools as a precautionary measure. Authorities in neighboring states, including New Jersey and Rhode Island, imposed similar restrictions to ensure public safety.

This marks the second major winter storm to hit the East Coast in less than a month, leading to growing frustration among residents.

“I’m fed up. I don’t want to see another snowflake,” said Vincent Greer, a resident of Wildwood, New Jersey, as he shoveled accumulated snow from in front of his building.

Ninth Victim Recovered After Deadliest U.S. Avalanche in Decades

Rescue teams in California on Saturday recovered the body of the ninth and final victim of a deadly avalanche in the Sierra Nevada mountains, according to the local sheriff’s office.

The avalanche struck a group of 11 skiers and four guides on Tuesday as they were returning from a three-day backcountry trip near Castle Peak, a 2,777-meter (9,111-foot) mountain and popular tourist destination on the U.S. West Coast.

Six people were rescued alive on Tuesday. Authorities said the incident marks the deadliest avalanche in the United States since 1981.

“All nine individuals who lost their lives in the February 17 Castle Peak avalanche have been safely recovered from the mountain,” the Nevada County Sheriff’s Office said in a statement.

“There are no words that can truly capture the magnitude of this loss, and our hearts grieve alongside the families affected by this catastrophic event,” Sheriff Shannan Moon said.

Officials had warned on Thursday that search operations would likely continue through the weekend due to severe weather conditions in the area.

Survivors were able to call for help shortly after the avalanche occurred. However, near-zero visibility and the risk of additional snow slides prevented rescue teams from reaching them for several hours.
