 | Kamchatka’s 2025 magnitude 8.8 earthquake generated a tsunami with 10–20% of the energy of the 1952 event, reflecting its smaller magnitude and predominantly deep fault slip. Shallow slip near the trench and coastal bathymetry amplified local run-up to nearly 20 m despite weaker waves across the Pacific. |

 | In Mexico City, heat-related social media posts rose sharply above 25°C and were more common in hotter, densely built areas. Posts described heat stress, poor sleep, difficult working conditions, uncomfortable transit and harassment linked to wearing lighter clothing. These accounts add everyday impacts to satellite and weather measurements. |

 | SWOT satellite data classified 84.4% of 800,000 km of irrigation canals across 22 Asian countries as moderately or highly observable for water-level monitoring. Wider canals, smooth slopes and open surroundings favored observation, while dense vegetation was the main limitation. |

 | Guliya ice cores from Tibet show reproducible oxygen isotope records and radioactive traces of the Laschamp geomagnetic excursion about 41,000 years ago. Comparison with cave records suggests the ice record extends beyond 128,000 years, supporting persistence of the ice cap through the last ice age into the Holocene. |

 | From January 1 to September 15, 2026, 34% of the global population was exposed to ozone concentrations well above WHO guidance. Exposure was highest in Asia, affecting 53% of its population. Heat waves, wildfires and human-caused emissions promoted ground-level ozone formation, highlighting links between climate change and harmful air pollution. |

 | Satellite-derived maps estimate vegetation fuel moisture across Australia at 20 m resolution, with observations about every five days. In August 2026, parts of the southern ACT were unusually dry despite a normal regional fire outlook. The maps can inform fire preparedness and prescribed-burn planning but must be combined with weather, fuel and field assessments. |

 | Complete loss of ice in East Antarctica’s Wilkes Subglacial Basin could raise global sea level by 3–4 meters. Past warming of 2–3°C above preindustrial levels caused substantial retreat, indicating vulnerability to warming. Sparse data on ocean temperatures and seafloor geometry prevent reliable estimates of future ice-loss rates. |

 | Groundwater recovery in Osaka is associated with land uplift averaging 4 mm per year and reaching 12 mm per year locally. Faults restrict groundwater flow, producing uneven recovery and uplift. Reducing groundwater extraction can slow or partly reverse subsidence, helping limit relative sea-level rise in coastal cities. |

 | Arctic sea-surface and sea-ice temperatures rose 4.2°C between 1982 and 2024, while sea ice declined by nearly 500,000 km² per decade since 1979. Ice retreat increases coastal erosion and habitat loss. Record-low Antarctic sea ice in 2022 coincided with large-scale emperor penguin breeding failure, underscoring their dependence on stable ice. |

 | Waste status depends on technology, markets and regulation, not material properties alone. Reusing cooking oil, whey and fly ash can conserve resources and reduce disposal, but reprocessing can also introduce health risks or recirculate pollutants. Biofuel incentives can raise used-oil prices while encouraging theft and fraudulent labeling. |

 | Sustained onshore winds, shallow bays and full-moon high tides amplified flooding during the September 2026 nor’easter. Sea-level rise increases coastal inundation even without stronger storms. Strong nor’easters are more likely during El Niño, and forecasts favor a wetter East Coast winter, but storm severity remains uncertain. |
| |
 | Satellite-constrained projections indicate net Antarctic ice loss this century even if warming is limited to 1.5°C, as increased snowfall cannot offset losses. Under very high emissions, Antarctica could contribute up to 25 cm of sea-level rise by 2100. Lower emissions reduce projected ice loss, although unmodeled processes remain a source of uncertainty. |

 | Storm surge modeling, spatial analysis and population vulnerability estimates inform hurricane evacuation zones along the Texas Gulf Coast. Transportation modeling of 88 scenarios produced evacuation clearance time estimates incorporated into HURREVAC to support emergency planning. |
| |
 | Global 1-km groundwater simulations classified 57% of locations as resilient, 15% as vulnerable and 26% as unstable in drought recovery. Recovery depends on climate, geology and landscape, with successive droughts reducing recovery capacity. Regions with intensive groundwater abstraction more often contain vulnerable and unstable systems. |

 | Interviews with 47 Latino, Caribbean and Black residents of one Florida HOA community documented perceived exclusion and barriers to participation in governance. Restrictive voting rules, cultural controls and HOA fees can limit residents’ agency and reinforce racial and socioeconomic inequalities in housing. |

 | At South Africa’s Somkhele coal mine, household asset and income losses exceeded R80 million in 2007–2018, while reported compensation totaled R3.6 million. Livelihood-based modeling projects losses of at least R157 million by 2038. Market replacement valuations omit future income and nonmarket harms, substantially understating mining-related losses. |
