Columbia researchers found aerosol pollution rose about 33% across 46 cities after U.S. embassies stopped publishing air-quality readings in 2025. The result is evidence that public monitoring data helps hold pollution down, though the published summary does not say whose behavior changed.

Colin Gleason's team used NASA's SWOT satellite to check machine-learning river models and found serious errors in under 10% of reaches. Those errors cluster on dammed, arid and Arctic rivers, among the reaches that matter most for water resources.

NC State satellite mapping shows North Carolina lost 21% of its coastal forest, about 64,220 hectares, between 1985 and 2021, mostly to rising seas. Measured per year, conversion to marsh, ghost forest and shrub after 2010 ran at about triple the earlier pace.

Researchers using 38 years of satellite data found wetland inundation tracked yearly runoff more closely than climate in 69% of 109 Prairie Pothole catchments. The finding is a correlation, and how much wetland data would sharpen streamflow forecasts has yet to be shown.

Chongzhao Zhang's team fed raw satellite radiance directly into aerosol simulations and cut prediction errors by about 50% in tests over China. A pretrained AI step makes the approach affordable, though the test scored aerosols against satellite data and left any forecast gains unmeasured.

Eos's Landslide Blog compared Planet Labs images from 12 and 25 August and found little change on the Langtang Lirung slope that collapsed on 26 August. The few changes it found are hard to tell from background activity, a problem for optical warning systems that would rely on such imagery.

University of Washington researchers say NASA's SWOT satellite can measure water levels on more than 85% of 800,000 km of Asian irrigation canals. The mission was never designed for canals, so the map points to monitoring from hardware already in orbit, with its scores checked against US canal measurements.

The August berg was the largest Arctic calving since 2020, but it broke along a fracture the team watching Petermann had not expected, leaving two rifts that together outline more than twice the area that left.

University of Arizona researchers find about 80% of the world's drylands swinging harder between wet and dry years across four decades of satellite data. Forecasts for rain-fed farms and rangelands built on the 13 vegetation models they tested assume steadier plants than the satellite record shows.

Dartmouth and Appalachian Mountain Club researchers found significant vegetation gains in 69% of alpine zones between the Adirondacks and the Gaspe. The growth runs fastest on wind-sheltered slopes, where ground surveys will have to settle whether rare flowering plants are losing out.

Sentinel-2 images show Sertung Island's vegetation index falling from 0.72 to about zero in the month spanning the September 2026 Anak Krakatau eruption. The researchers say ash over living plants gives the same signal, so survivors must be counted on the ground.

CIRES scientists measured a Petermann Ice Shelf river cutting below sea level to form an estuary that came and went from 2014 to 2018. A co-author suspects that cycle weakened the shelf ahead of its Manhattan-sized calving in August, though the imagery ends eight years earlier.

Calibrating penguin guano color against guano chemistry gave one team a krill-share model they could run backwards through an archive that starts in the 1980s. It is cheap, it covers a whole continent, and it is correlational about krill, the number everyone wants pinned down.
