For decades, countries around the world fought to reduce deadly air pollution caused by coal plants, shipping fuel, factories, and diesel engines—and the effort has saved millions of lives. But scientists are now warning that cleaner air has also revealed a hidden climate consequence: global warming may accelerate faster when certain pollutants disappear from the […]

A new generation of underwater autonomous robots is being deployed across coral ecosystems to help scientists monitor, protect, and even restore reefs threatened by climate change. These robotic systems—equipped with cameras, artificial intelligence, sensors, and robotic arms—can swim through fragile reef environments for hours while collecting detailed data on coral bleaching, water temperature, disease outbreaks,

UNICEF has warned that the escalating climate crisis could severely disrupt education for nearly 520 million children across Eastern and Southern Africa by 2050, as floods, droughts, cyclones, heatwaves, and food insecurity increasingly damage schools and destabilize communities. The region is already experiencing some of the world’s fastest-rising climate pressures, with extreme weather events forcing

Across sections of Greece’s coastline, abandoned “ghost” fish farms are polluting coastal waters, damaging marine ecosystems, and creating growing hazards for fishing boats and commercial ships. Rusting cages, broken nets, floating plastic pipes, and submerged metal structures from old aquaculture operations have been left drifting or partially sinking in the sea after companies shut down

Scientists have uncovered new evidence showing that certain fungi play a surprising role in influencing weather patterns by releasing microscopic particles into the atmosphere that help clouds and rain form. Many fungi eject huge numbers of spores into the air, especially in humid forests and tropical ecosystems. Researchers found that some of these spores contain

Scientists and public health experts are increasingly warning that protecting forests is not only an environmental priority but also a critical investment in human health. Forests help clean the air by absorbing pollutants and carbon dioxide, regulate temperatures during deadly heatwaves, protect freshwater supplies, and reduce the spread of certain infectious diseases by maintaining balanced

Researchers have developed a new photocatalyst system capable of converting plastic waste into hydrogen fuel using sunlight and a common acidic solution similar to battery acid. The process relies on photocatalysis, where specialized materials absorb solar energy and trigger chemical reactions that break down plastic molecules while releasing hydrogen gas. Scientists say the technology could

New environmental monitoring data suggests tropical forest loss declined in 2025 after reaching record-breaking levels in previous years, offering cautious optimism for some of the world’s most threatened ecosystems. Scientists tracking deforestation through satellite imagery reported reductions in forest clearing across parts of the Amazon rainforest, Central Africa, and Southeast Asia, driven by stronger environmental

China has launched a new high-precision Earth observation satellite designed to monitor greenhouse gases with far greater accuracy than earlier systems, marking a significant upgrade in space-based climate tracking. The satellite uses hyperspectral sensing technology to detect subtle changes in sunlight reflected from Earth’s surface and atmosphere, allowing it to estimate concentrations of carbon dioxide

In Finland, work continues on the Onkalo spent nuclear fuel repository, a facility built into 1.9-billion-year-old bedrock that is set to become the world’s first operational permanent repository for high-level nuclear waste. The site, located on Finland’s west coast near the Olkiluoto nuclear power station, is designed to store spent fuel hundreds of metres underground
