Assessment of timberline boundary shift in the mountainous ecosystems of Subpolar Urals from multispectral satellite imagery over the last 40 years [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Shifts in the habitat boundaries of woody plant species represent one of the continental-scale consequences of climate change. Mapping these shifts and quantitatively evaluating them is essential for an appropriate assessment of the carbon balance.

Variability of Pennsylvanian-Permian Carbonate Associations and Implications for NW Pangea Palaeogeography, East-Central British Columbia, Canada [PDF]

, 2012
Different stages of Pennsylvanian-Permian carbonate sedimentation in east-central British Columbia record a complex history of changing environments influenced by evolving palaeogeography and climate.

Elemental and molecular composition of humic acids isolated from soils of tallgrass temperate rainforests (Chernevaya taiga) by 1H-13C HECTCOR NMR spectroscopy [PDF]

, 2021
The soils of Chernevaya taiga (tallgrass fir-aspen hemiboreal rainforest) have high fertility in comparison with oligotrophic analogs formed in boreal taiga.

Variability of Autumn Tropical Pacific Yellowfin Tuna Tied to the Spring North Atlantic Tripole

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Climate change affects the spatial distribution and abundance of yellowfin tuna (Thunnus albacares, YFT) in the tropical Pacific, yet the mechanisms linking remote climate modes to YFT dynamics remain unclear. This study finds that the variability of autumn tropical Pacific YFT is tied to the spring sea surface temperature anomalies (SSTAs) of

Contrasting Arctic Amplification Response in the Community Earth System Model Large Ensembles and Implications for the North Atlantic Region

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 6, 28 March 2025.
Abstract The response of the polar jet to climate warming and rapid Arctic change is a leading uncertainty in climate projections and critical to the future of mid‐latitude surface weather. Previous studies suggest that CMIP5‐6 model projections fall into two groups of either Arctic‐ or tropically‐driven climate change, especially in the North Atlantic.

The distribution of the ammonite Gravesia (Salfeld, 1913) in the Kimmeridge Clay Formation (Late Jurassic) in Britain [PDF]

, 2010
Species of the ammonite Gravesia (Salfeld, 1913) have a widespread distribution in Europe over a relatively narrow stratigraphical range in the late Kimmeridgian and early Tithonian stages.

Microfacies and geochemistry of Kimmeridgian limestone strata in the Eastern Pontides (North‐East Turkey): Palaeoclimate and palaeoenvironmental influence on organic matter enrichment

The Depositional Record, Volume 11, Issue 1, Page 4-21, February 2025.
Kimmeridgian limestone (KL) strata are one best example of a peritidal carbonate that records palaeogeographic and palaeoclimate conditions in Eastern Pontide, Eastern Black Sea region. The KL strata are represented by well‐preserved dark grey lime‐mudstones that archive important geochemical proxy.

Interdecadal Springtime Aerosol Increase in the North Indian Ocean Observed From the Satellite AVHRR Instrument

Journal of Geophysical Research: Atmospheres, Volume 129, Issue 19, 16 October 2024.
Abstract A 38‐year aerosol optical thickness (AOT) satellite product from the Advanced Very High‐Resolution Radiometer (AVHRR) is used to investigate the aerosol variabilities in the North Indian Ocean (NIO). A dipolar mode with a notable meridional contrast between the equatorial and northern NIO is revealed by the second mode of Empirical Orthogonal ...

Role of Eurasian Snow Cover in Linking Winter‐Spring Eurasian Coldness to the Autumn Arctic Sea Ice Retreat

Journal of Geophysical Research: Atmospheres, Volume 124, Issue 16, Page 9205-9221, 27 August 2019., 2019
Abstract An anomalous “north‐south” dipole mode of the snow water equivalent (SWE) persisting from winter to spring is detected over the Eurasian mid‐to‐high latitudes in this study. Using observational data sets and numerical experiments of the Community Atmospheric Model (5.0), we show that this mode contributes to prolonged winter‐springtime ...
