Unexpected Consequences of Solar Geoengineering
Solar engineering is not a substitute for mitigation, and concerns about its risks and unintended impacts are supported by the recent discovery of overlooked atmospheric…
Observing the Impact of Convective Aggregation on Water Vapor
Remote sensing measurements for water vapor isotopic composition enable us to assess how convective aggregation influences the atmospheric hydrological cycle.
Dryline-Induced Thunderstorms Over the Southern Africa Plateau
Scientists present the first comprehensive study of dryline formation and associated thunderstorms over the southern African plateau from 2010 to 2021.
Northern Ecosystems are Shaped by Snow
Changing climate in the Arctic leads to a shorter snow season but deeper snow in the depths of winter. Under the insulating snow, biological processes…
Uncovering Mantle Heterogeneities Beneath Drifting Continents
Computational models of the composition and volumes of magmas during continental rifting evolution provide clues on the heterogeneities of the deep melting mantle.
Seismometers Listening at Rivers to Measure Sediment Transport
Bedload sediment, transported throughout an alpine catchment by a flood, was remotely tracked in detail by analyzing the ground vibrations recorded by a network of 24 seismic sensors.
Source Selection Essential to Inter-Source Cross-Correlation
Inter-source correlograms yield coherent signals upon careful consideration of source mechanisms and source-receiver geometry, affording new means of characterizing planetary interiors.
Pliocene Conveyer Belt in the Pacific
Ocean Drilling Program cores and helium isotopes put better constraints on the ocean circulation in the north Pacific.
Low-Frequency Quakes Have Modest Effect on Slow Earthquake Cycle
Slow slip phenomena on subdaily scales, captured by seismic and GNSS data, show that low-frequency earthquakes are incidental to larger magnitude slow earthquakes, in which aseismic slip dominates.
Wet Conditions Delay Wildfire Detection
When accompanied by a considerable amount of rainfall, ignition of wildfire by lightning over forested land may not be detected until days later.
Barnacles Help Reconstruct Drift Path of Malaysia Airlines Flight MH370
Careful calibration of isotopes in a barnacle shell growing on ocean debris – in this case an airplane part – informs a new forensic method to identify its most probable drift path.
Gaps and Challenges in Coastal Adaptation Research
A new study reviews 650 empirical studies on coastal adaptation, revealing knowledge gaps on its implementation, policy, governance, and economic contexts, especially in the Global South.
Using Bayesian Estimation to Improve Methane Inventories
A Bayesian, optimal estimation evaluation of state-of-the-art methane inventory with satellite-based emissions from 2009 to 2018 finds substantial differences for livestock, rice, and coal emissions.
A Multidecadal View of Oceanic Storage of Anthropogenic Carbon
A decline in the ratio of ocean carbon accumulation to atmospheric carbon dioxide growth between 1994-2004 and 2004-2014 suggests a reduction in the sensitivity of the ocean carbon sink.
Frozen Riverbanks May Erode Faster in a Warming Arctic
Frozen flume experiments reveal the sensitivity of permafrost riverbank erosion to water temperature, bank roughness, and pore-ice content.
