Eos is a science news magazine published by the American Geophysical Union, covering research and developments in earth and space sciences.
Ice cloud tops over mountains rose and cooled 2 to 4 times faster than over adjacent lowlands in 2003 to 2022 satellite data, Eos reports. The paper tracked cloud properties, so any effect on mountain water supply is untested.

Rong Huang's team tied magnetite crystal shape to oxygen across more than 200 modern seafloor samples and built an equation for absolute levels. The calibration comes from today's oceans, and the authors suggest it extends to hotter climates of the past.
Reality
Sediment cores from Jili Lake in Xinjiang show the lake rose about 20 meters in 250 years of dry climate, during the centuries of peak Silk Road trade. The cores measure water, and the step to busier oasis markets is the team's interpretation.
Reality
Özpolat and colleagues found hillslope erosion 2 to 3 times more intense under discontinuous permafrost, using cores from 12 Alaska lakes. The cores come from landscapes near their present state, and the authors say the gap may be site-specific.
Reality
Researchers matched oxygen isotopes in one Biggenden banded snail's shell to ex-tropical-cyclone rain across about 4.5 years of its life. It is one shell from a limestone-free park, so use at other sites is a projection.
Reality
Hilary Chang's team used a 1,600-channel fiber cable in a 3 km Utah borehole to measure microquakes and found stress drop did not track magnitude. The same paper warns that the cable's own settings can skew the magnitudes behind that finding, so teams adopting the method need an independent check.
Reality
Researchers on British Columbia's long-term logging experiment found soil carbon fell 52% in five years on plots stripped of residue and forest floor. Twenty years later those plots were still 33% below preharvest levels, so the way a stand is cut stays in its soil carbon account for decades.
Reality
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.
Reality
FEMA administrator Cameron Hamilton has redefined emergency management as 'the strategic coordination of emergency services,' effective immediately. Eos reports that the new wording appears to rule out funding for disaster mitigation and recovery.
Reality
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.
Reality
Authors of a Reviews of Geophysics paper argue wildfire smoke keeps reacting as it ages, so downwind air can carry pollutants the fire never emitted. Air-quality forecasts and exposure estimates improve when they model that aging, the authors write.
Reality
Planetary scientist Mark Sykes rebuilt 15 years of NASA research and analysis spending from FOIA data and found it flat, down 30% in real value since FY2011. He says the shortfall is costing NASA scientists and ideas, a claim his dollar figures support only indirectly.
Reality
Pablo Santos-Sanz's team used the James Webb Space Telescope to find Chariklo's inner ring 42% more opaque and its outer ring barely visible. Occultations are rare, so for now the team can show that the rings changed but not why, or how long they will last.
Reality
Recently burned Alaskan forest reburns 1 to 3 orders of magnitude less often than older forest, Gaglioti and colleagues find in 1984-2020 fire data. Extreme fire weather weakens that barrier most in young stands, so a scar's value as a firebreak depends on its age and the weather.
Reality
Jha and Byrne varied the rate at which dry air mixes into convective plumes across ERA5 and CESM2, and found it significantly moves moist-heat extremes outside the tropics, which means a swept parameter sits underneath the wet-bulb projection.
Reality
Eighty percent of respondents reported at least one harmful interaction during fieldwork, and three quarters of the worst incidents went unreported. Severe violence and misconduct were excluded by design, which makes the headline figure a floor rather than a prevalence estimate.
Reality
Morgan Chakraborty and colleagues sampled an active Red Sea brine pool, a depression they suspected was a dead one, and three ordinary seafloor sites. The sediments of both pools carried the same metal enrichment.
Reality
A Bayesian inversion of 60 days of pressure and velocity records from Torrey Pines State Beach separates the infragravity band and puts roughly 28% of its energy in edge waves running along the shore.
Reality
The Landslides paper on the Matai'an dam breach traces the failing slope back before 1985 and through a magnitude 7.4 earthquake. Taiwan relocated 8,524 people before the dam gave way, and 24 still died.
Reality
Whether a forest's biogenic emissions cool the planet or warm it depends on the air they enter, and the aerosol term is loose enough that a carbon-only planting ledger cannot say which way a stand cuts.
