Marine mammals, including deep-diving whales and dolphins, exhibit high levels of PFAS contamination regardless of habitat, indicating that even remote or deep-sea environments do not protect against these persistent pollutants. PFAS accumulation poses risks to immune, endocrine, and reproductive health, raising concerns for marine biodiversity and ecosystem health.

Prolonged droughts, each exceeding 85 years and affecting up to 91% of the Indus Valley Civilization region, coincided with decreased rainfall and a 0.5°C temperature rise. These environmental changes led to shifts in settlement patterns toward river areas and contributed to the civilization’s gradual decline rather than a sudden collapse.

High-resolution data from the SWOT satellite revealed that the 2025 Kamchatka tsunami exhibited complex, dispersive wave patterns, challenging the traditional view that large tsunamis are non-dispersive. Analysis combining satellite and DART buoy data indicated the earthquake rupture extended 400 km, longer than previous estimates, highlighting the need to refine tsunami models and integrate diverse data sources.

Climate change accelerates plastic breakdown into microplastics, increasing their mobility, persistence, and ecological harm. Rising plastic production and climate effects intensify these impacts, threatening nutrient cycles, soil health, and species, especially apex predators. Urgent systemic action is needed to limit microplastic pollution and transition to a circular plastics economy.

A novel bathymetric mapping framework integrates ICESat-2 LiDAR, optical, and SAR data to achieve high-accuracy, wide-coverage shallow-water depth mapping, including in turbid regions. The PAWLP method enables robust wave-based depth estimation, while multi-source data fusion and temporal sample-transfer strategies enhance spatial consistency and reliability for coastal applications.

A new framework called “Weather Commons” is proposed as a democratic, community-centered approach to weather management, contrasting with top-down, technocratic methods. This concept promotes collective stewardship of weather-related resources, aiming to balance technological interventions with societal engagement and critical reflection on humanity’s evolving relationship with weather.

Severe flooding across Indonesia, Thailand, and Malaysia has resulted in dozens of deaths, widespread displacement, and significant infrastructure damage. Heavy monsoon rains, intensified by climate change and exacerbated by factors such as urbanization and deforestation, have overwhelmed local authorities and left many areas inaccessible, with ongoing risks as further rainfall is expected.
