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.

Venezuela Earthquakes Spark Diplomatic Thaw With Former Critics

The devastating earthquakes that struck Venezuela have triggered an unprecedented diplomatic thaw between Caracas and several governments that had maintained strained relations with the country, raising hopes that the humanitarian response could pave the way for broader international engagement under the administration of U.S. President Donald Trump.

The United States, Chile, Argentina, El Salvador and Israel were among the first countries to announce humanitarian assistance, deploy search-and-rescue teams or establish direct contact with acting President Delcy Rodríguez to coordinate relief efforts in the hardest-hit areas.

Canada also joined the international response by announcing humanitarian aid while opening a domestic debate over the importance of maintaining diplomatic representation in countries such as Venezuela to better respond to emergencies and assist its citizens abroad.

The wave of international cooperation marks a sharp contrast to the diplomatic tensions that followed Venezuela’s disputed presidential election on July 28, 2024, in which Nicolás Maduro was declared the winner.

In the aftermath of that vote, the governments of Argentina, Chile, Costa Rica, Panama, Peru, the Dominican Republic and Uruguay publicly questioned the official election results, triggering one of the region’s most significant diplomatic crises in recent years.

The Venezuelan government responded by withdrawing its diplomatic personnel from several of those countries and demanding the departure of their representatives, further deepening the country’s international isolation.

The humanitarian emergency created by the twin earthquakes has now prompted renewed communication between Caracas and governments that had previously suspended or significantly reduced diplomatic engagement, underscoring how major natural disasters can temporarily reshape international relations despite longstanding political disagreements.

Venezuela Earthquake Death Toll Surpasses 1,700 as Search for Survivors Continues

Venezuelan authorities have raised the death toll from last week’s twin earthquakes to more than 1,700, as rescue teams continue searching for survivors in the country’s hardest-hit coastal region.

According to the latest official report released on Sunday, the powerful earthquakes, measuring magnitudes 7.2 and 7.5, have claimed at least 1,719 lives. National Assembly President Jorge Rodríguez also reported that 5,034 people were injured, while 15,866 have been displaced and another 22,619 are receiving medical care.

The United Nations has expressed growing concern over the scale of the disaster, estimating that as many as 68,000 people could still be missing.

La Guaira bears the brunt of the disaster

The coastal state of La Guaira has suffered the greatest loss of life and the most extensive damage. The Venezuelan government has declared the area a disaster zone and placed it under military control as emergency operations continue.

Five days after the earthquakes struck, search-and-rescue teams remain on the ground, supported by additional heavy equipment and international rescue crews. However, hopes of finding more survivors beneath the rubble continue to diminish with each passing day.

One of the most dramatic rescue operations unfolded Monday in Catia La Mar, where emergency teams from El Salvador, Mexico, and Venezuela worked together to reach a 21-year-old man who has remained trapped inside a collapsed building since the earthquakes struck.

The twin earthquakes hit Venezuela on June 24, with the epicenter located between San Felipe and Yumare in the country’s northern region. The first quake, measuring magnitude 7.2, struck at 6:04 p.m. local time. Just 39 seconds later, a second and stronger magnitude 7.5 earthquake occurred farther to the southeast. Combined, the seismic activity lasted nearly three minutes, causing widespread devastation across several regions of the country.

Looting Spreads in Venezuela’s Hardest-Hit Areas After Deadly Earthquakes

Not even the wires were left behind at a small grocery store. Before the ground had even stopped shaking, looting and theft began in the areas hardest hit by the double earthquake that struck Venezuela.

Reports of robberies have multiplied in the coastal state of La Guaira, located near Caracas and now transformed into a landscape of collapsed buildings and debris.

Videos circulating on social media show groups of people removing boxes of household appliances from a damaged store. Other images show similar boxes being carried on top of vehicles and motorcycles.

Social media platforms have also been filled with accusations against police officers and military personnel who allegedly stole from homes and even from victims who died during the disaster.

A branch of a major pharmacy chain was looted, along with supermarkets and other businesses. Some residents have described the situation as “disaster tourism,” while others say the looting reflects hunger and desperation among people who lost everything in a country already facing a prolonged economic crisis.

“Is it fair that our own people turn against our own people?” said María Esther Bernal, 71, who rented commercial spaces to Chinese merchants, all of which were looted. “They left nothing behind, not even the wallpaper. They even took the cables,” she said.

“Next door, a man died. He was Chinese. People walked over his body while they looted the place. It was a supermarket,” she added.

An AFP journalist witnessed looting in La Guaira since Thursday, following the earthquakes.

Jenifer Mayora, 34, defended some of the actions, saying that “the things people took were because the owners of the stores allowed us to take them.”

However, she criticized the limited response from authorities. “I have been waiting for a mattress so my children can sleep,” she said.

Residents have expressed anger over what they describe as a slow and insufficient response from authorities after the double earthquake, which has left around 1,450 people dead and tens of thousands missing.

Communities are demanding not only faster rescue operations in La Guaira, but also stronger security measures and urgent assistance with food, water, and medicine.
