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.

Marco Rubio launches U.S. campaign to “dismantle” the International Criminal Court

U.S. Secretary of State Marco Rubio announced Monday (July 13, 2026) the launch of a diplomatic campaign aimed at “dismantling” the International Criminal Court (ICC), a key institution in the global justice system, while pressuring Washington’s allies to withdraw from the organization, which he accused of interfering in U.S. affairs.

“The ICC represents an intolerable threat to American sovereignty: it claims the authority to prosecute and even imprison military personnel and officials acting in defense of the national interests of the United States,” Rubio said.

He also accused the court of waging “a war against our country, not with bullets or missiles, but with statutes, agreements and the power of what they call international law.”

The United States is not a signatory to the Rome Statute, the treaty that established the ICC. The Trump administration has previously imposed sanctions on senior court officials over investigations into alleged war crimes committed by U.S. personnel in Afghanistan and actions targeting Israeli officials, a key U.S. ally.

“Step by step, if necessary”

The new State Department initiative proposes banning ICC personnel from entering the United States and expanding sanctions against court members and affiliated organizations.

The plan also includes increasing pressure on Washington’s allies, particularly countries that “benefit from the U.S. security umbrella,” to publicly reject ICC actions and distance themselves from the institution.

The Trump administration will summon foreign ambassadors and senior officials to highlight what it describes as “ICC abuses” and encourage them to withdraw from the court.

Washington also plans to increase scrutiny of countries that refuse to reject what the administration calls the ICC’s “claimed authority” while continuing to rely on U.S. assistance.

Rubio said the ICC seeks to become “a global unaccountable arbiter.” In an opinion piece published Monday in The Wall Street Journal, the secretary of state said that with the support of its allies, the United States would dismantle the ICC “step by step, if necessary.”

ICE reverses course and moves forward with New Jersey migrant detention facility project

The administration of President Donald Trump has reversed course and resumed plans to convert a warehouse in New Jersey, purchased for $129.3 million, into a migrant detention facility with capacity for up to 1,500 people, according to a court filing in the state.

U.S. Immigration and Customs Enforcement (ICE) submitted a document Friday to a federal court in New Jersey stating that it will continue moving forward with plans to establish the facility in the township of Roxbury.

According to the court filing, ICE had previously informed the court on June 29 that it had decided to abandon the plan to convert the property into a detention center.

However, on July 8, Department of Homeland Security (DHS) officials notified attorneys that, “after reconsideration,” the agency intended to continue evaluating the renovation of the warehouse for use as a migrant detention facility.

“DHS officials further informed counsel that, as of July 10, the agency’s deliberations remain ongoing,” the document stated.

The decision to revive the project comes two weeks after The New York Times reported that ICE had decided not to proceed with plans to establish new detention facilities as part of the Trump administration’s immigration detention and deportation strategy.

According to that report, the agency had planned to sell seven warehouses, including the Roxbury property, for more than $700 million or transfer them to other federal agencies.

The New Jersey facility proposal is part of broader efforts by the Trump administration to expand immigration enforcement infrastructure amid its push to increase detention capacity and accelerate deportations of undocumented immigrants.

Judge rules Trump’s IRS lawsuit was a “bad faith” attempt to manipulate the judicial process

A federal judge ruled Monday that a lawsuit filed by President Donald Trump against the Internal Revenue Service (IRS) was an attempt to “manipulate the judicial process” and determined that the case was brought in bad faith.

U.S. District Judge Kathleen Williams ordered sanctions against the attorneys involved in the lawsuit, which led to an effort to create the now-defunct $1.8 billion “anti-weaponization” fund aimed at addressing alleged political targeting by government institutions in favor of Trump allies.

The lawsuit was also used to justify a government order that sought to provide Trump and his companies with immunity from any past tax-related matters.

In a 56-page opinion, Williams sharply criticized both the Department of Justice (DOJ) — saying the government’s response to the case disregarded agency policies and may have violated the law — and the private attorneys who filed the lawsuit on Trump’s behalf.

“The very nature of the lawsuit and the conduct of the parties and counsel since its filing make clear that this was an attempt to use the court to provide legitimacy to an agreement designed to grant immunity to individuals and entities connected to the president and to allocate billions of taxpayer dollars to remedy grievances that the law does not recognize,” Williams wrote.

The judge also ordered that her opinion be referred to attorney disciplinary authorities in New York and Washington, which are already reviewing previous ethics complaints involving Acting Attorney General Todd Blanche and Deputy Attorney General Stanley Woodward.

Williams criticized the Justice Department for abandoning its responsibility to defend the interests of the United States, arguing that the government entered into an agreement that departed from its position in similar legal cases, ignored DOJ policies and pursued objectives beyond what is permitted by law.

“By abandoning its responsibility to vigorously defend the interests of the United States, the government entered into an agreement that deviated from its litigation position in similar cases, ignored Department of Justice policies and achieved objectives that exceeded those authorized by law, as well as others expressly prohibited,” Williams wrote.

The judge also referred one of Trump’s private attorneys to the Florida Bar for possible disciplinary action and barred another lawyer representing the president from appearing before the U.S. District Court for the Southern District of Florida for one year.

The ruling adds another legal setback for attorneys involved in cases connected to Trump’s administration and raises new questions about the conduct of government lawyers and private counsel involved in the IRS lawsuit.
