Speleothem Paleoclimatology for the Caribbean, Central America, and North America [PDF]

, 2019
Speleothem oxygen isotope records from the Caribbean, Central, and North America reveal climatic controls that include orbital variation, deglacial forcing related to ocean circulation and ice sheet retreat, and the influence of local and remote sea ...

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

H11 meltwater and standard 127 ka Last Interglacial simulations suggest more modest peak temperatures for both Greenland and Antarctica: a multi-model study of water isotopes [PDF]

Climate of the Past
The Last Interglacial (LIG) period, approximately 130 000 to 115 000 years ago, represents one of the warmest intervals of the past 800 000 years. Here, we simulate water isotopes in precipitation over Antarctica and the Arctic during the LIG, using ...

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 ...

Phylogenetic structure and formation mechanism of shrub communities in arid and semiarid areas of the Mongolian Plateau [PDF]

, 2019
The mechanisms of species coexistence within a community have always been the focus in ecological research. Community phylogenetic structure reflects the relationship of historical processes, regional environments, and interactions between species, and ...

Advancing subsurface biosphere and paleoclimate research: ECORD–ICDP–DCO–J-DESC–MagellanPlus Workshop Series Program Report [PDF]

Scientific Drilling, 2015
The proper pre-drilling preparation, on-site acquisition and post-drilling preservation of high-quality subsurface samples are crucial to ensure significant progress in the scientifically and societally important areas of subsurface biosphere and ...

Initiation of a Stable Convective Hydroclimatic Regime in Central America Circa 9000 Years BP [PDF]

, 2020
Many Holocene hydroclimate records show rainfall changes that vary with local orbital insolation. However, some tropical regions display rainfall evolution that differs from gradual precessional pacing, suggesting that direct rainfall forcing effects ...

A checklist of invertebrates from Norwegian caves and mines

Fauna Norvegica, 2013
The invertebrates hitherto registered from Norwegian caves and mines are presented in a checklist. Each species is listed with localities, cavity type with altitude, total length and depth, and also minimum age ka (i.e.
