Biodiversity is declining globally at rates "unprecedented" in human history, and the rate of species extinction is accelerating, warns a landmark report from the UN Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). The Global Assessment, approved at the 7th session of the IPBES Plenary in Paris last week, foresees grave impacts for people around the world. "The overwhelming evidence of the IPBES Global Assessment, from a wide range of different fields of knowledge, presents an ominous picture," said IPBES chair Sir Robert Watson. "The health of ecosystems on which we and all other species depend is deteriorating more rapidly than ever. We are eroding the very foundations of our economies, livelihoods, food security, health and quality of life worldwide."

Rising temperatures in the Himalayas will melt at least one-third of the region's glaciers by the end of the century even if the world's most ambitious climate change targets are met, according to a new report. If those goals are not reached, the Himalayas could lose two-thirds of their glaciers by 2100, according to the Hindu Kush Himalaya Assessment, released Feb. 4 by the Kathmandu-based International Centre for Integrated Mountain Development. Under that scenario, the Himalayas could heat up by 8 degrees Fahrenheit (4.4 degrees Celsius) by century's end, bringing radical disruptions to food and water supplies, and mass population displacement. Glaciers in the Hindu Kush-Himalayan Region, which spans over 2,000 miles of Asia, provide water to nearly a quarter of the world's population.

Things are approaching a crisis point in the long battle of wills between Venezuela and the White House. Juan Guaidó, president of the opposition-controlled National Assembly, swore himself in as the country's "interim president" before a crowd of tens (by some accounts, hundreds) of thousands of supporters in Caracas on Jan. 23. Perhaps in an abortive move to pre-empt this, the SEBIN political police detained him on his way to a rally three days earlier, but later released him without charge. At his auto-inauguration, he declared President Nicolás Maduro's re-election last May illegitimate, and himself the only legitimate executive authority in the country. Donald Trump immediately announced that he is recognizing Guaidó—quickly joined by Canada and several Latin American governments.

Protests have been mounting across Sudan in response to the nation’s acute economic crisis. Inflation reached 70% in November and many have been forced to spend significant portions of their income on bread, leading to local media designating the demonstrations as "bread protests." Protesters have repeatedly called for President Omar al-Bashir, who has been in power since 1993, to step down. President Bashir promised reforms on Dec. 25 after police blocked protesters who marched on his presidential palace. The protests have been organized by professional organizations and trade unions as well as Sudan's principal opposition group, the Umma Party. Sudan's government on Dec. 20 shut off internet access to prevent the protesters from organizing via social media. According to an Amnesty International report released Dec. 24, at least 37 protesters have been killed so far as Sudanese authorities attempt to quell the demonstrations by releasing tear-gas and firing live ammunition, sparking international criticism.

UN Special Rapporteur on human rights and the environment David Boyd called Oct. 8 for accelerated action to combat climate change. The statement comes after the Intergovernmental Panel on Climate Change (IPCC) released a report on the impacts of global warming of 1.5°C. Boyd said that climate change is "one of the greatest threats to human rights" and will have devastating effects on the "rights to life, health, food, housing, and water, as well as the right to a healthy environment." In order to meet human rights obligations, Boyd called on counties to exceed their Paris Agreement obligations. If the temperature is allowed to increase 2.0°C, it would result in "human rights violations upon millions of people."

At least one is reported dead as angry protests have spread across Tunisia in response to an austerity package imposed by the government under pressure from the International Monetary Fund. The protester died due to tear-gas inhalation Jan. 8 in Tebourba, 40 kilometers west of Tunis, with demonstrations reported from several other cities and towns, including Sidi Bouzid, cradle of the country's 2011 revolution. Under the new budget, which took effect Jan. 1, fuel prices are hiked, and new taxes imposed on housing, cars, phone calls, Internet services, and several other items. Hamma Hammami, leader of the opposition Popular Front, pledged to keep up the pressure, telling reporters: "We will stay on the street and we will increase the pace of the protests until the unjust financial law is dropped."

Sudanese authorities on Jan. 7 carried out mass arrests and confiscated newspapers as protests exploded over rising bread prices and severe economic austerity. One student was killed amid demonstrations in Geneina, capital of West Darfur state. Protests were also reported from the cities of Nyala, South Darfur; al-Damazin, Blue Nile atate; and the capital Khartoum. The unrest broke out as bakeries doubled the price of bread following a government decision to increase the price of flour nearly fourfold. The decision was part of a package of austerity measures issued by the Sudanese government under the country's 2018 budget, seeking to address the spiralling inflation rate, currently at about 25%.

A wave of protests across Iranian cities began as a response to inflation and economic pain, but shows signs of escalating to a popular repudiation of clerical rule. Spontaneous protests first broke out Dec. 28 in the northeast city of Mashhad, where security forces responded with tear-gas and water cannons. Since then, protests have been reported from Kermanshah and Hamadan in the west, Rasht and Sari in the north, Ahvaz in the southwest, and Qom and Isfahan in central Iran. Arrests are also reported from the capital, Tehran, where a group of demonstrators attempted to occupy a public square. Protests began with the slogan "Death to high prices!" But as repression mounted, demonstrators began chanting "Death to the dictator," in apparent reference to President Hassan Rouhani and the ruling mullahs.
