Arctic cryosphere and Milankovitch forcing of Great Basin paleoclimate

, 2017
Although Great Basin paleoclimate history has been examined for more than a century, the orbital-scale paleoclimate forcings remain poorly understood. Here we show – by a detailed phasing analysis of a well-dated stalagmite δ18O time series – that Great ...

Linking genome size variation to phenotypic selection on target traits

Ecology, Volume 107, Issue 6, June 2026.
Abstract Genome size (GS) is known to be highly variable among angiosperm species. However, this variation can also occur within species. Both interspecific and intraspecific variations in GS have been often found to be linked to phenotypic traits. Therefore, selective pressures acting on these target traits may indirectly shape GS evolution within and

Trends and variability of heat waves in Europe and the association with large-scale circulation patterns

Weather and Climate Extremes
Heat waves, defined by consecutive days of abnormally high temperatures exceeding local or regional norms, have been extensively studied during the summer season. However, their characteristics and driving forces in mid-to-late spring (April and May) and

Loess Studies in Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

Missing Summer Westerly Jet Barotropic Governor Effect Explains Climate Models—Observation Discrepancies in the Indian Monsoon Trends

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract The South Asian summer monsoon has exhibited a pronounced Northwest India‐Indo‐Gangetic Plains rainfall dipole since 1999, with northwest India experiencing a 24.6% increase, while rainfall in the Indo‐Gangetic Plain has decreased by 4.4%.

Standardized Frameworks for n‐Alkane Compound‐Specific Isotope Analysis: Assessments and Analytical Platform for Data Processing Workflows and Uncertainty Estimation

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Post‐acquisition processing of plant wax n‐alkane isotope data in compound‐specific isotope analysis (CSIA) remains variable and often lacks transparency. To improve inter‐laboratory comparability and data reliability, we present standardized, reproducible workflows for CSIA that address key challenges in drift correction, scale normalization,

Response of the Nitrogen Isotopic Composition of Planktic Foraminifer Tissue to Surface Ocean Nutrient Cycling: A Case Study in the Northern South China Sea

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract This study presents data on geographically small‐scale patterns of nitrogen (N) isotope signals (δ15N) within the northern South China Sea (SCS) imprinted on planktic foraminifers (PF). PF from net tows on the shelf, continental slope, and in pelagic waters from summer 2019 were analyzed for δ15N.

Late‐Stage Debris Flows Eroded Aeolis Mons in Gediz Vallis, Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract How the ancient climate of Mars transitioned to its current cold, hyperarid state is recorded by the sedimentary rocks preserved on its surface. Gale crater, the Curiosity rover landing site, is one such location, where the central mountain, Aeolis Mons, preserves an extensive sedimentary record. Curiosity has demonstrated that the Aeolis Mons

Sensitivity of Soil Chemical Erosion Rate to Climate and Dust Along a 2.8‐km Elevation Transect at San Jacinto Mountain, California

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 6, June 2026.
Abstract Chemical weathering is of wide interest because it breaks down minerals, releases nutrients, weakens rock, and draws down atmospheric CO2. To quantify the sensitivity of soil chemical erosion rate to climate and dust, we measured soil chemical erosion rate, dust deposition rate, and soil climate at 18 ridgetop sites along a ∼2.8‐km elevation ...
