New Constraints on the Timing and Pattern of Deglaciation in the Húnaflói Bay Region of Northwest Iceland Using Cosmogenic 36CA Dating and Geomorphic Mapping

open access: yes, 2017
Understanding the evolution and timing of changes in ice sheet geometry and extent in Iceland during the Last Glacial Maximum (LGM) and subsequent deglaciation continues to stimulate much active research.

Sensitivity of Anthropogenic Cloud Droplet Number Change to Preindustrial Emission Inventories and Physics Parameterizations

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Understanding the preindustrial (PI) to present‐day (PD) change in cloud droplet number concentration (ΔNd) is important to constrain the anthropogenic influence on clouds and aid future model projections. Perturbed parameter ensemble simulations of PI and PD conditions in the Energy Exascale Earth System Model (E3SMv3) reveal two locations ...

A review of paleoclimate reconstruction based on soil physical and chemical properties

open access: yesGuan'gai paishui xuebao
Soils preserve critical geochemical and mineralogical information that records past climatic conditions. Consequently, soil physical, chemical, and biological properties have become important proxies for paleoclimate reconstruction.

Temperature‐Driven Silicate Weathering Feedbacks Terminated the Middle Eocene Climatic Optimum

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Continental hydroclimate dynamics and its responses during the Middle Eocene Climatic Optimum (MECO, ∼40 Ma) remain largely unexplored. Here, we present high‐resolution multi‐proxy records from four East Asian lake basins that demonstrate precipitation, chemical weathering, and terrestrial input underwent multi‐phase changes during the MECO ...

Cultural Responses to Climate Change During the Late Holocene [PDF]

open access: yes
This study describes the effect of drought on past civilizations and peoples and their response as civilizations or cultures. The site includes four case studies drawn from New and Old World civilizations that document societal responses to prolonged ...

Acquisition of Self‐Reversed Magnetization in Greigite Driven by Antiparallel Vortex‐Core Coupling During Low‐Temperature Oxidation

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Self‐reversed magnetization, acquired antiparallel to the external field, can complicate the interpretation of paleomagnetic directional records, particularly in altered greigite‐bearing sediments with anomalous magnetizations. The underlying physical process for this self‐reversal remains poorly constrained.

Geographic Variation of Cirques on Iceland: Factors Influencing Cirque Morphology

open access: yes, 2017
Cirques are one of the most common glacial landforms in alpine settings. They also provide important paleoclimate information (e.g. Meierding 1984; Evans 2006). The purpose of this study is to fill in gaps in the climate record of Iceland by conducting a

Prenucleation Species Dictate Foreign Ion Incorporation in the Biomineral Precursor Amorphous Calcium Carbonate

open access: yesAdvanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
ACC forms via aggregating prenucleation clusters that gatekeep its chemical composition. Ion identity steers the path: Ba and Sr substitute Ca in clusters, thereby inhibiting nucleation, with a dose‐dependent switch of Sr to induction. Mg partitions into Mg‐rich and Mg‐poor clusters; the latter form ACC, expelling Mg.

Does the public discuss other topics on climate change than researchers? A comparison of explorative networks based on author keywords and hashtags

open access: yes, 2019
Twitter accounts have already been used in many scientometric studies, but the meaningfulness of the data for societal impact measurements in research evaluation has been questioned.

Long‐Term Historical Slowdown in Atlantic Meridional Overturning Circulation

open access: yesEnvironmetrics, Volume 37, Issue 4, May 2026.
ABSTRACT Atlantic Meridional Overturning Circulation (AMOC) is an important component of the climate system that profoundly affects the climate of surrounding areas. AMOC is expected to slowdown due to anthropogenic climate change. The scientific community has long been at odds regarding how much AMOC has already slowed down, and whether there was any ...
