 | Age strongly shapes food-related greenhouse gas emissions, with adolescents and young adults showing the highest per capita dietary emissions globally. Population aging increases total dietary emissions mainly via demographic shifts rather than more emission-intensive senior diets. Meat and dairy dominate emissions, with emerging economies’ dietary transitions further increasing impacts. Effective mitigation requires age- and context-specific dietary and production policies that balance emission reduction with nutritional adequacy. |

 | Idealized simulations indicate sustained supershear ruptures generate higher peak ground velocities than subshear ruptures, remaining elevated up to ~20 km and exceeding current ground-motion model predictions. Near-fault shaking lasts longer due to a dual pulse from supershear and subshear fronts. Supershear events produce larger spectral accelerations, especially at frequencies critical for 3–5 story buildings, suggesting implications for seismic design. |

 | Desiccation of the Aral Sea has exposed sediments that emitted 748 Mt CO₂ since 1960, while 605 Mt CO₂ remain stored and at risk of release. Reflooding could halt these emissions and restore carbon sink function, with potential carbon credit value of US$3.6–18 billion. Partial restoration via improved water management is technically possible and could be climate-financed. |

 | A two-step remediation strategy for PFAS-contaminated farmland combines surface application of crushed alkaline rock to raise soil pH and enhance plant-mediated PFOS uptake with conversion of harvested biomass to biochar, thermally destroying PFOS and PFOA. The approach restores agricultural use, is orders of magnitude cheaper than excavation or soil incineration, and simultaneously removes atmospheric CO₂ via enhanced weathering and biochar carbon sequestration. |

 | Neutralization of acid mine drainage from metal mining generates substantial CO₂ emissions that have been largely unaccounted for. Measurements and experiments in a high-acid-drainage copper mining region in southeast Spain indicate that past and future CO₂ from drainage neutralization can exceed conventional copper production footprints by more than an order of magnitude. These emissions persist for centuries to millennia after mine closure and can dominate the long-term carbon budget of metal production, implying a need to revise life-cycle assessments and remediation strategies. |

 | Geo-Sense is a portable distributed acoustic sensing system that uses seafloor-laid fiber-optic cables to measure minute strains and vibrations for long-term, high-resolution monitoring. It enables real-time observation of earthquakes, underwater landslides, currents, fluid seepage, and volcanic activity at targeted locations. Planned deployments aim to monitor diverse geohazards and support informed marine management. |

 | Satellite data from 2000–2023 indicate that river inflow from the Tigris–Euphrates, not local rainfall, is the primary control on vegetation and surface water in Iraq’s Mesopotamian Marshes. Vegetation loss coincides with reduced streamflow and regional droughts and is associated with higher land surface temperatures, implying a warming feedback. Effective transboundary river management is critical to maintain wetland integrity. |

 | Projected UK sea-level rise of 0.4–0.6 m by 2100 and 1.2–1.8 m by 2300 increases coastal flood risk areas by 13% and 56%, respectively, exposing up to 1.7 million additional people by 2300 even if current pledges are met. Low-lying regions such as the Wash, Humber Estuary, and, under extreme ice-sheet instability, large parts of London face severe flooding, underscoring the need for both rapid emissions cuts and long-term adaptation. |

 | Two companion papers analyze the 2025 Texas Hill Country floods, showing that an experimental high-resolution WoFS-FLASH system could have predicted extreme, record-breaking Guadalupe River flows 5–7 hours in advance. The event resulted from a slow-moving supercell embedded in an unusually moist tropical plume over a vulnerable watershed, where simultaneous flood waves from converging tributaries greatly amplified inundation at Camp Mystic. |

 | Japan is experiencing extreme heat, with a new category “cruelly hot days” for temperatures ≥40 °C and heatstroke alerts in most prefectures. Authorities characterize the persistent heat as a disaster, noting increased hospitalizations and deaths from heatstroke. The event aligns with a trend of more frequent, intense heatwaves linked to anthropogenic climate change. |

 | Extended producer responsibility makes manufacturers legally and financially responsible for post-consumer waste, typically via producer responsibility organizations and recycling targets. Implementation varies widely and is difficult to evaluate due to data gaps and confounding factors. Eco-modulated fees aim to better link design choices to costs. A curated open bibliography compiles global EPR literature to inform policy and practice. |

 | Elementary pupils used handheld thermal cameras to map surface temperatures around schools and identify heat hotspots. Analysis of >1,700 thermal images showed nature-based and green–blue infrastructure areas were typically 1–3°C cooler than non‑green areas. The program improved or maintained climate-change understanding in >80% of participants and supported pupil-generated cooling design solutions. |

 | Mandatory curbside soft plastic collection in the UK has been delayed to 2030 due to inadequate infrastructure, while only about 7% of such plastics are currently recycled. The packaging extended producer responsibility scheme charges by weight, incentivizing lighter but often less recyclable flexible plastics. Funding to councils is not ring-fenced for waste services, weakening system improvements. The article argues that policy should prioritize reduced packaging production and costs based on real environmental harm rather than recyclability alone. |

 | EFSA reduced the acceptable daily intake of trifluoroacetic acid (TFA), a highly persistent PFAS, from 0.05 to 0.014 mg/kg body weight per day, based on evidence that TFA alters thyroxine levels. TFA is widespread in water, soil, food, and is considered unlikely to be genotoxic, but its carcinogenicity and immune effects require further study. The new limit will guide stricter EU water standards. |

 | Greece is undergoing a three-day heat wave peaking at about 43 °C, with highest values in Thessaly, eastern regions, and parts of the Peloponnese. Authorities imposed maximum wildfire alert and banned outdoor work during peak heat, with fines for violations and remote work advised for vulnerable groups. The timing is climatologically unusual, marking one of the latest ≥40 °C events since 2011. |

 | An automated camera-based system (ADIS) scanned 14,500 km² of global ocean surface from 2019–2024, generating 27 million images and identifying over 20,000 floating macroplastic objects to map debris densities. Ground-truthing in the Great Pacific Garbage Patch showed undercounting by a factor of 5–6 but consistent spatial patterns, enabling correction. The upgraded ADIS2.0 autonomously detects debris with GPS, expanding coverage to ~54,000 km² and supporting temporal analyses of floating plastic distributions. |

 | Shifts in European atmospheric circulation, especially more frequent and persistent summer high-pressure systems, account for about 55% of the observed summer soil-moisture drying trend. Direct thermodynamic warming and circulation-driven variability jointly control drought severity, producing strong year-to-year modulation and large uncertainty in future European summer drought projections and associated risks. |

 | An intense heat wave in France from June 17 to July 2 caused an estimated 5,764 excess deaths, a 36% increase over expected mortality and the highest heat-related excess mortality since 2003. The Paris region was most affected, with ~1,999 excess deaths (~80% above expected), and nearly half of all deaths occurred in hospitals, about one-third at home, and the remainder mainly in care homes. |
