Hurricane Maria's destruction on Puerto Rico could spawn one of the largest mass migration events in the United States' recent history, as tens of thousands of storm victims flee the island territory to rebuild their lives on the mainland. Some 97% of the island's 3.4 million residents are still without power. About half of the island's residents do not have running water. And no one knows when things will be fixed. Scientific American warns that the displaced islanders, thousands now awaiting flights from San Juan's Luis Muñoz Marín airport, might be among the United States' newest "climate refugees," a demographic that includes former residents of the Louisiana coast and of shrinking islands in Alaska's Bering Strait.

Human rights groups in Libya have accused the United Arab Emirates of committing war crimes in the country, including killing hundreds of civilians. The rights groups said on Sept. 26 that the UAE committed these crimes through direct air-strikes on Libya, and by backing the renegade general Khalifa Haftar. The findings were presented at a press conference on the sidelines of the UN Human Rights Council meeting in Geneva, Switzerland. Libyan witnesses and survivors spoke of extrajudicial killings, forced hunger, and displacement that they or their kin experienced at the hands of Haftar in Derna and Ganfouda, provinces in Libya's east. Survivors affiliated with  the organization Human Rights Solidarity also described alleged UAE air raids in the Libyan capital Tripoli in August 2014. (Al Jazeera)

As results come in from the Kurdistan Regional Government's referendum on independence from Iraq, the Baghdad government is rejecting the vote as illegitimate, refusing all talks on the matter and threatening punitive action. "We are not ready to discuss or have a dialogue about the results of the referendum because it is unconstitutional," said Iraqi Prime Minister Haider al-Abadi  in a speech broadcast on state TV.  Raising the stakes, Abadi has given the KRG until the end of the week to surrender control of its two international airports or face a shutdown of international flights.

The rights situation in Crimea "has significantly deteriorated under Russian occupation," the UN Human Rights Office finds in a Sept. 25 report (PDF), citing arbitrary arrests. disappearances, torture, infringements of the Geneva Conventions. The report especially highlights discrimination against those who have resisted taking up Russian citizenship. Individuals without Russian Federation citizenship are denied many rights, including the right to vote or run for office, the right to own agricultural land, and the right to register with a religious community. The groups most susceptible to rights violations are "those who formally rejected citizenship; civil servants who had to renounce their Ukrainian citizenship or lose their jobs; and Crimean residents who did not meet the legal criteria for citizenship and became foreigners." This prominently includes the Crimean Tatars, who have strenuously rejected Russian annexation of the peninsula. (RFE/RL, Jurist)

San Francisco on Sept. 20 filed a lawsuit against five fossil fuel companies due to expected expenses the city will incur from global warming. The companies named in the suit are BP, Chevron, ConocoPhillips, ExxonMobil and Royal Dutch Shell—chosen because they are "the largest investor-owned fossil fuel corporations in the world as measured by their historic production of fossil fuels." The suit claims the companies knew of the effects of fossil fuels on global warming since the late 1970s or early '80s, but nonetheless "engaged in large-scale, sophisticated advertising and public relations campaigns to promote pervasive fossil fuel usage." The suit seeks an order that the defendants fund an abatement program for the building of seawalls to protect San Francisco from rising sea levels.

The International Tribunal for the Law of the Sea ruled (PDF) Sept. 23 in favor of Ghana in a lengthy maritime dispute with Ivory Coast. The case, which was brought to the international body by Ghana in 2014, was an attempt to clarify the boundary between the two countries, as both countries were vying for oil in the contested area. The court unanimously ruled in favor of Ghana, dismissing the claim that Ghana violated the territorial rights of Ivory Coast when it expanded its oil exploration in the area. The ruling definitively creates a boundary, in the form of a straight line running from the land boarder of the two nations. The ruling came in accordance with the UN Convention on the Law of the Sea.

In his final address to the UN General Assembly as president of Colombia, Juan Manuel Santos delivered a message of peace, highlighting the agreement reached between his government and the FARC guerillas, and describing it as a model for the rest of the world. "If we were able to put an end to an armed conflict in Colombia that has left hundreds of thousands dead and millions of victims and displaced persons, there is hope for other ongoing conflicts in the world," Santos stated.

The government of Venezuela, under growing pressure from US sanctions, is telling oil traders that it will no longer receive or send payments in dollars, Dow Jones reported Sept. 13. Oil traders who export Venezuelan crude or import oil products into the country have begun converting their invoices to euros. The state oil company Petróleos de Venezuela SA (PdVSA), has instructed its private joint venture partners to convert existing cash holdings into euros. Plugging the switch, Venezuela-based state media outlet TeleSur writes: "The petrodollar is more important for US global domination than either arms exports or Hollywood culture, because it allows the US to be the biggest exporter of the dollar bills the rest of the world needs to be able to buy oil. Venezuela has decided to start de-dollarizing its economy."
