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.

Climate change is "unequivocal" and rapidly intensifying, and some of the changes already in motion—such as continued sea level rise—are irreversible over hundreds to thousands of years, finds the latest report from the Intergovernmental Panel on Climate Change (IPCC), released Aug. 9. The IPCC Working Group I report, "Climate Change 2021: the Physical Science Basis," was approved by 195 member governments of the IPCC, having been prepared by 234 scientists from 66 countries. The report concludes that human influence has warmed the planet at a rate that is unprecedented in at least the last 2,000 years. Human-induced climate change is already affecting many weather and climate extremes in every region across the globe—including heatwaves, droughts, and tropical cyclones.

Children in Raqqa, northeast Syria, are still living among ruins, with limited water, electricity, and access to education, four years after the city was taken from ISIS, according to a new report by Save the Children. Thousands of people have returned to Raqqa since the battle for the city ended in 2017, and the report estimates that up tp 330,000 people are currently living there. But levels of rebuilding and rehabilitation of housing remain low, with children living in constant fear of their homes collapsing on top of them. Research estimates that 36% of the city's buildings remain entirely destroyed.

The government of Greenland announced July 23 that it will suspend all oil exploration, saying the territory "wants to take co-responsibility for combating the global climate crisis... The future does not lie in oil. The future belongs to renewable energy, and in that respect we have much more to gain."  While no oil has been found yet, the US Geological Survey estimates there could be 17.5 billion undiscovered barrels below the territory's lands and waters. Many had hoped potential reserves could allow Greenland to achieve independence, compensating for the annual subsidy of 3.4 billion kroner ($540 million) the territory receives from Denmark.

The Amazon has long played a vital part in balancing the global carbon budget, but new evidence suggests the climate scales are tipping in the world's largest rainforest. Now, according to a study published July 14 in Nature, the Brazilian Amazon is emitting more carbon than it captures. Southeastern Amazonia, in particular, switched from being a carbon sink to a carbon source during the study period. Emissions were high in 2010, when the study began, because of a dry El Niño year, and researchers expected to see emissions return to normal afterward. But this never happened. The reason: emissions from fires.
