    China’s aggressive campaign to reduce air pollution has delivered dramatic improvements in public health and air quality over the past decade. However, new research suggests that the same policies may have unintentionally contributed to a small but measurable increase in global warming. The study, published in Geophysical Research Letters, finds that sharp reductions in sulfur dioxide emissions from China have lowered atmospheric sulfate aerosols tiny particles that previously reflected sunlight back into space and exerted a cooling effect on the planet. While the environmental and health benefits of cleaner air are undeniable, scientists say the climate system is responding in complex ways.

An estimated half of the world’s coral reefs experienced significant bleaching during the 2014–2017 global marine heatwave, according to a major international study led by researchers at the Smithsonian Tropical Research Institute (STRI). The findings, published in Nature Communications, represent the most geographically extensive analysis of coral bleaching ever conducted. The study concludes that more than 50% of coral reefs worldwide suffered substantial bleaching during what scientists call the “Third Global Coral Bleaching Event,” with approximately 15% experiencing significant coral mortality. Researchers warn that a fourth global bleaching event, which began in 2023, is already underway. Coral reefs provide enormous benefits to society, supporting fisheries, tourism, coasta...

    Meteorologists are closely monitoring conditions over the Arctic as new data suggests early February could represent a significant turning point in the stability of the polar vortex a development that may influence weather patterns across North America, Europe and parts of Asia in the coming weeks. The concern follows an unusually warm start to the year in parts of the Arctic. In early January, researchers in Svalbard recorded milder-than-normal surface conditions, while upper-air measurements showed temperature anomalies as high as 30 degrees Celsius above seasonal averages at certain altitudes in the stratosphere. These anomalies are affecting the polar vortex, a large-scale circulation of strong winds high above the North Pole that typically traps cold air in t...

    Officials in Suriname are attempting to reverse a controversial agribusiness contract that could lead to the clearing of more than 113,000 hectares (280,000 acres) of Amazon rainforest a move experts warn would jeopardize the country’s carbon-negative status and undermine its environmental commitments. The land in question lies in the northwestern district of Nickerie and was earmarked in 2024 under a public-private partnership between Suriname’s Ministry of Agriculture and Suriname Green Energy Agriculture N.V., a company focused on sugarcane ethanol and bioenergy production. Although the agreement was signed under the previous administration, critics say the legal framework remains active and clearing has begun in recent months allegedly without the necessary en...

    In a landmark conservation effort, the red-necked ostrich has returned to the Arabian Peninsula after disappearing from the wild there nearly a century ago. The reintroduction marks a significant milestone in Saudi Arabia’s ambitious rewilding initiative aimed at restoring native megafauna to vast, sparsely inhabited desert landscapes. The critically endangered bird, historically known as the “camel bird,” was released into the six-million-acre Prince Mohammed bin Salman Royal Reserve, Saudi Arabia’s third-largest protected area. Once celebrated in Arab poetry and noted by Roman scholars, the ostrich had been extinct in the region for approximately 100 years. Part of a Broader Rewilding Vision The return of the ostrich is part of the long-term “ReWild Arabia” p...

    In a dramatic effort unfolding amid towering snow walls and sub-zero temperatures, the Border Roads Organisation (BRO) is racing against time to reopen the historic Mughal Road in Jammu and Kashmir a crucial lifeline that connects the Kashmir Valley with the Pir Panjal region. Massive snow blowers roar to life each morning, cutting through layers of compacted snow and ice that have buried the road for weeks. The operation is not merely about clearing a highway; for thousands of residents, it represents the restoration of trade, mobility and access to essential services that have been severely disrupted by winter’s grip. Stretching from Shopian in the Valley to Bafliaz in Poonch, the Mughal Road reduces travel time between the two regions to about three hours. Howe...

    The Pacific island nation of Palau, often described as one of the world’s last untouched paradises, is taking decisive steps to protect its people from the growing threats of climate change. With support from the United Nations, the country is building and strengthening a national network of climate-resilient disaster shelters designed to withstand extreme weather events and safeguard vulnerable communities. Palau, an archipelago of more than 500 islands in the western Pacific Ocean, is among the countries least responsible for global climate change. Yet it is one of the most exposed to its impacts. Rising sea levels, intensifying typhoons, storm surges and coastal flooding are increasingly shaping daily life and national planning. For Seth Techitong, the changes ...

    Vulnerable communities across Chad are now receiving improved climate, meteorological and hydrological services, along with life-saving early warnings, following the successful completion of a six-year project funded by the Climate Risk and Early Warning Systems (CREWS) initiative. The US$3.15 million project, implemented between 2019 and 2025, was designed to strengthen Chad’s national capacity to deliver climate and early warning services in key sectors and high-risk communities. Led by the World Bank’s Global Facility for Disaster Reduction and Recovery (GFDRR), with US$1.5 million implemented by the World Meteorological Organization (WMO), the initiative has laid the foundation for a more integrated, modern and people-centred early warning system in the country. ...

    When devastating floods swept through Mozambique in 2000, the story of a baby born in a tree as her mother clung to branches above the rising Limpopo River captured international attention. The child, later nicknamed Rosita by the press, became a symbol of hope and resilience in the face of disaster. But her life, which began amid catastrophe, ended quietly on 12 January 2026. Rosita reportedly died of anaemia at a provincial health centre, a condition that could have been treated within a stronger and better-resourced health system. Her death coincided with yet another wave of severe flooding in southern Mozambique, underscoring the country’s persistent vulnerability. In late January 2026, weeks of heavy rainfall submerged large parts of southern Mozambique, affe...

    After major disasters, public debate often frames them as unexpected or unprecedented events. This reaction is not necessarily due to a lack of warnings. Rather, it reflects how societies process shock and how authorities frequently portray disruption as unavoidable instead of the outcome of earlier institutional choices. In reality, extreme weather events are rarely unpredictable. Scientists are often able to identify increased risks of storms, floods, droughts, or other hazards days or even weeks in advance. Yet despite these warnings, destructive outcomes continue to occur. An examination of the catastrophic floods that struck Luxembourg in July 2021, the most damaging disaster in the country’s recorded history, provides insight into why this happens. By recons...
