The South Pacific nation Vanuatu announced Sept. 25 its intention to seek an advisory opinion from the International Court of Justice on the rights of present and future generations to be protected from the adverse consequences of climate change. Speaking at the UN General Assembly, Vanuatu's Prime Minister Bob Loughman warned that the climate crisis is "increasingly eluding the control of individual national governments," and stressed the need for a global solution. The announcement set out his government's plan to coordinate the efforts of Pacific Island states and other vulnerable nations to seek clarification on the legal duties of large emitters of greenhouse gases. Its immediate goal is to establish a Pacific states coalition to drive the initiative.

A lot of attention is paid to the possible impacts of the climate crisis on international migration—particularly the potential movement of people from the Global South to the Global North. Now, a new report from the World Bank says that climate change could force 216 million people to migrate within their countries by 2050. People living in under-developed regions—such as parts of sub-Saharan Africa—are the most likely to be forced to move. Immediate and concerted effort to reduce carbon emissions could reduce the scale of climate migration by as much as 80%, however. The report is a reminder of what gets overlooked in the focus on South-North migration: There are currently 48 million internally displaced people compared to 20.7 million refugees. Of those refugees, 80% live in countries neighboring their country of origin, and only 16% live in countries in the Global North.

Close to 80,000 people have been displaced in Tambura County, in South Sudan's Western Equatoria, as a result of fighting between government forces and the opposition SPLA-IO–even though both sides are supposed to be forming a new unified army. A delay to security sector reform continues to set back implementation of a 2018 peace agreement. The Pretoria-based Institute of Security Studies has warned that South Sudan's "militarized political culture" could see tensions "boiling over"—threatening the national unity government. Faction fighting within SPLA-IO has added to the insecurity. Meanwhile, the World Food Programme is suspending aid to more than 100,000 displaced people in Wau, Juba, and Bor beginning in October—part of a three-month "prioritization exercise" driven by a finance crunch. The fall in funding is despite the country experiencing the highest rate of food insecurity since independence in 2011, with more than 60% of South Sudanese going hungry. Months of flooding has added to that toll.

A record number of environmental defenders were murdered last year, according to a report issued this week by advocacy group Global Witness. The report, "Last Line of Defense," counts 227 activists killed around the world in 2020—the highest number recorded for a second consecutive year. Many of the murders were linked to resource exploitation—logging, mining, agribusiness, and hydroelectric dams. Since the 2015 Paris Agreement on climate change, the organization found on average of four activists have been killed each week.

Denmark and Costa Rica jointly announced that they are launching an alliance of nations committed to setting a firm date to completely phase out use and production of fossil fuels. The two countries hope to present the initiative, tentatively dubbed the Beyond Oil & Gas Alliance (BOGA), at the upcoming UN climate summit in Glasgow, Scotland. Nearly 60 countries have made some sort of net zero emissions pledge, but only a handful of those have actually set a target in law or enacted bans on new fossil fuel exploration and production. An International Energy Agency report released earlier this year found that new fossil fuel exploration needs to halt by 2022 in order to keep warming within the limits set by the 2015 Paris Agreement. "We are in a paradoxical situation right now where many countries have pledged to become carbon neutral but are actually still planning to produce oil and gas after that date," Danish Minister of Climate & Energy Dan Jorgensen told Reuters.

At least 90 people have been killed in wildfires that have swept through northern Algeria over the past weeks. The blazes have consumed some 100,000 acres, mostly in the northeastern Kabylia region and its central province of Tizi Ouzou. While remaining silent on the role of climate change, the Algerian government seems to be exploiting the disaster for political purposes. President Abdelmadjid Tebboune on Aug. 18 said most of the fires were "criminal" in origin, and blamed them on regional rival Morocco. The two countries were already in a diplomatic tiff before the new accusations. "The incessant hostile acts carried out by Morocco against Algeria have necessitated the review of relations between the two countries," the presidency said in a statement, adding that there will be an "intensification of security controls on the western borders." Algeria's western border with Morocco has already been sealed and heavily militarized since 1994.

More than 500,000 people are in need of emergency assistance in Haiti's southern peninsula, where last week's 7.2-magnitude earthquake has killed more than 2,100 people and injured more than 12,200. Aid and medical efforts are hampered by debris-strewn roads, rain from Tropical Storm Grace, a shortage of working hospitals, and gang violence. The private Bernard Mevs Hospital in the capital, Port-au-Prince, where some of the injured have been sent, was closed Aug. 19 as part of a two-day shutdown to protest the kidnapping of two doctors. In recent years, Haiti has been beset by violent gangs who patrol many of the country's transport routes. Some villagers were also reportedly blocking aid shipments, saying they were also desperate for help. The southern peninsula has yet to recover from Hurricane Matthew, which killed at least 546 people in 2016. Prime Minister Ariel Henry has promised to speed up aid efforts—more than 30,000 families have been displaced, and there are fears of cholera due to lack of safe water, sanitation, and shelter. The United States has deployed several helicopters, aircraft, and the USS Arlington to help with relief efforts. France also sent a ship with humanitarian cargo, a helicopter, and more than two dozen soldiers.

Nigerian authorities imposed a curfew in Jos, capital of north-central Plateau state, after at least 20 Muslim travelers passing through the city were massacred by a presumed Christian militia Aug. 14. The Muslims, mostly of the Fulani ethnicity, were in a convoy of vehicles, returning to their homes in Ondo and Ekiti states from a celebration in neighboring Bauchi state marking the start of Muharram, the Islamic new year. In Jos, the convoy was caught in a traffic jam, and the vehicles set upon by militiamen—the occupants slain with machetes, daggers and other weapons. The assailants were apparently Christians of the Irigwe ethnicity. Northern and central Nigeria have for years seen growing violence between Muslim semi-nomadic herders and Christian farmers over control of land and water.
