Climate models suggest that climate change could reduce the Southern Ocean's ability to absorb carbon dioxide (CO2). However, observational data actually shows that this ability has seen no significant decline in recent decades....

Ocean color satellites provide essential insights into water quality and ecosystem dynamics by estimating chlorophyll, suspended matter, and dissolved organic material. Atmospheric correction, the process of removing scattering and absorption from satellite signals, is central to these analyses....

Accurate land cover mapping underpins biodiversity protection, climate adaptation, and sustainable land use. Despite advances in remote sensing, satellite-only approaches remain limited by cloud cover, revisit intervals, and the lack of ground-truth data. Dynamic products such as Dynamic World have improved timeliness but still struggle to capture sudden transitions or...

Land use and land cover (LULC) information underpins studies in climate science, disaster management, food security, and ecosystem protection. Advances in satellite imaging have improved resolution, but high-resolution land cover mapping still faces major hurdles....

A study led by University of Arizona researchers shows that decades of groundwater pumping by humans has depleted Tucson-area aquifers far more than natural climate variation. Published in the journal Water Resources Research, the study provides the first multi-millennial reconstruction for the region that places human impacts on groundwater into...

Brazilian navigator Tamara Klink told AFP she encountered "very little" sea ice on her solo sail through the Northwest Passage—a rare feat that would have been impossible without an icebreaker ship three decades ago....

Nearly 80% of the world's poorest, or about 900 million people, are directly exposed to climate hazards exacerbated by global warming, bearing a "double and deeply unequal burden," the United Nations warned Friday....

A new international study co-led by IIASA researchers and Japanese partners aims to democratize the way global climate scenarios are developed. The authors propose a transparent, inclusive research platform that invites participation from scientists worldwide—especially from emerging and developing regions—to ensure that the foundations of climate policy analysis are globally...

Georgia and northern Florida are likely to be hardest hit by increasing hurricane-induced power outages along the Atlantic coast in the future, with Hispanic, non-white and low-income populations most affected, according to new research led by the University of Michigan....

Montreal's methane (CH4) emissions are unevenly distributed across the island, with the highest concentrations in the city's east end, McGill researchers have found. The worst polluters include the city's largest snow dump, which emits methane at levels comparable to the city's current and former landfills, and natural gas leaks....
