Progress in Paleoclimate Modeling* [PDF]
Abstract This paper briefly surveys areas of paleoclimate modeling notable for recent progress. New ideas, including hypotheses giving a pivotal role to sea ice, have revitalized the low-order models used to simulate the time evolution of glacial cycles through the Pleistocene, a prohibitive length of time for comprehensive general ...

On the Evolution of Paleoclimate and Paleoenvironment in Eastern Beijing Plain in the Last 70,000 Years Based on the Sediment Chronological Framework [PDF]
To study the paleoenvironment and paleoclimate of eastern Beijing Plain, this paper, based on particle size analysis and sporopollen analysis, constructs a sediment chronological framework.

DASH: a MATLAB toolbox for paleoclimate data assimilation [PDF]
Paleoclimate data assimilation (DA) is a tool for reconstructing past climates that directly integrates proxy records with climate model output. Despite the potential for DA to expand the scope of quantitative paleoclimatology, these methods remain ...

Reconstructing the Last 71 ka Paleoclimate in Northeast China by Integrating Typical Loess Sections
Long-term continuous deposits and well-preserved thick loess sections are natural archives for the reconstruction of global climate change. However, the loess sections are often discontinuous owing to soil erosions and accumulations.

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement
Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Regional variability of diatoms in ice cores from the Antarctic Peninsula and Ellsworth Land, Antarctica [PDF]
The presence of marine microfossils (diatoms) in glacier ice and ice cores has been documented from numerous sites in Antarctica, Greenland, as well as from sites in the Andes and the Altai mountains, and attributed to entrainment and transport by winds.

Regional validation of the use of diatoms in ice cores from the Antarctic Peninsula as a Southern Hemisphere westerly wind proxy [PDF]
The Southern Hemisphere westerly winds are among the most important drivers of recently observed environmental changes in West Antarctica. However, the lack of long-term wind records in this region hinders our ability to assess the long-term context of ...

Decadal Scale Variability of Larsen Ice Shelf Melt Captured by Antarctic Peninsula Ice Core
In this study, we used the stable water isotope record (δ18O) from an ice core drilled in Palmer Land, southern Antarctic Peninsula (AP). Utilizing δ18O we identified two climate regimes during the satellite era.

Hotspots for warm and dry summers in Romania [PDF]
The combined effect of hot and dry extremes can have disastrous consequences for society, the economy, and the environment. While a significant number of studies have been conducted regarding the variability of the individual hot or dry extremes in ...
