First evidence of industrial fly-ash in an Antarctic ice core

Scientific Reports, 2023
Spheroidal carbonaceous particles (SCPs) are a component of fly-ash, the particulate by-product of industrial high temperature combustion of fuel-oil and coal-series fuels.

Perspectives of regional paleoclimate modeling [PDF]

, 2018
Regional climate modeling bridges the gap between the coarse resolution of current global climate models and the regional-to-local scales, where the impacts of climate change are of primary interest.

Paleoclimate quantitative reconstruction and characteristics of continental red beds: a case study of the lower fourth sub-member of Shahejie Formation in the Bonan Sag

Journal of Petroleum Exploration and Production Technology, 2023
Varied origins have the ability to construct the continental red beds, such as paleoclimate, provenance, drainage status, etc. Reconstructing paleoclimate is the key to investigate the origin. Thus, this paper outlines the normal distribution constrained

Assessment of the southern polar and subpolar warming in the PMIP4 last interglacial simulations using paleoclimate data syntheses [PDF]

Climate of the Past
Given relatively abundant paleo-proxies, the study of the last interglacial (LIG, ∼ 129–116 000 years ago, ka) is valuable to understanding the responses and feedback of the Southern Ocean and Antarctica in a warmer-than-preindustrial climate.

Reconstruction of a Two-Dimensional Blocking Index During the Last Four Hundred Years Using Gridded Temperature and Precipitation Data

Atmosphere
We present a two-dimensional reconstruction of blocking frequency indices in the Atlantic-European region spanning the last 400 years. Our approach is based on a simple field reconstruction scheme similar to the principal component regression method. The

Baradla-Domica Cave

, 2022
The Quaternary epoch is noted for not only many cycles of glacial growth and retreat, but also impactful climate and precipitation variability. The present study brings an insight into the boundaries of Pleistocene and Holocene series from a high ...

Drivers of winter Arctic sea ice variability

npj Climate and Atmospheric Science
Winter Arctic sea ice concentration (SIC) variability reflects both anthropogenic warming and internal climate variability, but separating their Arctic signatures remains difficult.

Paleoclimate-induced stress on polar forested ecosystems prior to the Permian–Triassic mass extinction

Scientific Reports, 2022
The end-Permian extinction (EPE) has been considered to be contemporaneous on land and in the oceans. However, re-examined floristic records and new radiometric ages from Gondwana indicate a nuanced terrestrial ecosystem response to EPE global change ...
