Introduction to Holocene Climate

We reconstructed the early-mid Holocene climate changes in the southeastern margin of the Mu Us Desert by combining magnetic susceptibility (MS) and total organic carbon (TOC) analyses.

BP pollen and brGDGT sequence from Lake Ayrag documents the Mongolian Late Holocene climate and human impact variations.

Understanding late Holocene climate variation on the northern Tibetan Plateau is essential for understanding regional climate dynamics, especially the potential response to mid-latitude westerlies.

The Early Holocene Climate Optimum is distinctly imprinted in our record as a sudden decrease in χlf values and an increase in magnetic grain size ratio values (indicating finer iron oxide grains), suggesting a rapid thawing of the ice-sheet in response to a warm climate.

It is likely that Late Pleistocene—Early Holocene climate variation related to sea level and precipitation was forcing agent for epigean ostracode dominance in subterranean environments of the Peninsula.

Discrete phases of high or low flooding influence are recognised, and these correspond with large-scale Holocene climate history.

A repeating pattern of multi-centennial-scale Holocene climate events has been widely (globally) documented, and they were termed Rapid Climate Change (RCC) events.

2 simulation and discuss the vegetation trend in the context of the simulated Holocene climate change.

The simulated vegetation trend is discussed in the context of the simulated Holocene climate change.

The sediment section records a middle Holocene climate transition in the southern Gulf ~5000-4000 cal yr BP, supporting a northward migration of climate patterns along the western North America margin, from the southern Gulf of California to Alaska.

However, the strengthened monsoon in Early to Middle Holocene climate model simulations cannot sustain vegetation in the Sahara or account for the increased humidity in the Mediterranean region.

Thus early records of rice farming in Henan and Shandong were easily accommodated by early to mid Holocene climates.

We reconstructed the early-mid Holocene climate changes in the southeastern margin of the Mu Us Desert by combining magnetic susceptibility (MS) and total organic carbon (TOC) analyses.

Here, we demonstrate how hydrological conditions were modified by humans against the backdrop of Holocene climate change in southwestern Amazonia.

In the Pacific Northwest of North America, endangered Garry oak ecosystems have a complex history that integrates effects of Holocene climate change, Indigenous land management, and colonial settlement during the Anthropocene.

The Early Holocene Climate Optimum is distinctly imprinted in our record as a sudden decrease in χlf values and an increase in magnetic grain size ratio values (indicating finer iron oxide grains), suggesting a rapid thawing of the ice-sheet in response to a warm climate.

Differences were identified and characteristics were determined in the vegetation structure during the final phase of the Holocene climate optimum and multidirectional climatic fluctuations in the Late Holocene.

Paleoclimate studies in Patagonia show a high Holocene climate variability, strongly controlled by the intensity and latitudinal position of the Southern Westerly Winds.

The investigation of formation, stabilization and age of the respective landforms permitted an assessment of Holocene climate variability in Rondane and its connectivity to landform evolution.

Tree-ring δ18Ocell values have previously been used to track Holocene climate variations in East Asia, as δ18Ocell values are primarily controlled by meteoric water δ18O (δ18OMW) and relative humidity.

It is likely that Late Pleistocene—Early Holocene climate variation related to sea level and precipitation was forcing agent for epigean ostracode dominance in subterranean environments of the Peninsula.

We show that (1) preserved pollen assemblages are clearly imprinted on the extremities of the ecosystem range but mitigated and unclear on the ecotones; (2) for both proxies, inferred relationships depend on the geographical range covered by the calibration database as well as on the nature of samples; (3) even if local calibrations suffer from reduced amplitude of climatic parameters due to local homogeneity, they better reflect actual climate than the global ones by reducing the limits for saturation impact; (4) a bias in climatic reconstructions is induced by the over-parameterization of the models by the addition of artificial correlation; and (5) paleoclimate values reconstructed here are consistent with Mongolia–China Late Holocene climate trends and validate the application of local calibrations for both pollen and GDGTs (closest fit to actual values and realistic paleoclimate amplitude).

Due to the coastal environment of the Lower Yangtze, both the strengthening East Asian summer monsoon (EASM) and rising sea-level likely influenced the early to mid-Holocene climate transition.

The sediment section records a middle Holocene climate transition in the southern Gulf ~5000-4000 cal yr BP, supporting a northward migration of climate patterns along the western North America margin, from the southern Gulf of California to Alaska.

However, the strengthened monsoon in Early to Middle Holocene climate model simulations cannot sustain vegetation in the Sahara or account for the increased humidity in the Mediterranean region.

We quantify the evolution of the gradient and of mid-latitude moisture both in a new compilation of Holocene palaeoclimate records spanning from 10° S to 90° N and in an ensemble of mid-Holocene climate model simulations.

Holocene climate reconstructions are useful for understanding the diverse features and spatial heterogeneity of past and future climate change.

Strong similarities in Holocene climate reconstructions derived from multiple proxies (BSi, TOC – total organic carbon, δ13C , C∕N , MS – magnetic susceptibility, δ15N ) preserved in sediments from both glacial and non-glacial lakes across Iceland indicate a relatively warm early to mid Holocene from 10 to 6 ka, overprinted with cold excursions presumably related to meltwater impact on North Atlantic circulation until 7.

Pollen and charcoal data indicate concurrent grassland development with limited fuel biomass and less fire activity, despite late Holocene climate conditions that were conducive to expanded forest cover.

Considering recent archaeobotanical data indicating the presence of both West Asian winter crops and East Asian summer millets in the valley as early as 4500 BP, we argue that rather than Malthusian cycles of growth and collapse in Kashmir, early populations likely drew on a broad range of available domesticates and varied ecotopes across the valley to allow a Boserupian response to changing Holocene climate conditions.

Understanding how they have responded to Holocene climate fluctuations and anthropic impacts provides essential information to put into a historical context the magnitude and unique features of the current global change.

A quantitative assessment of the effects of Holocene climate fluctuations on islands area and inter‐island connectivity is crucial to finely reconstruct past biodiversity dynamics and forecast species responses to future changes.

A repeating pattern of multi-centennial-scale Holocene climate events has been widely (globally) documented, and they were termed Rapid Climate Change (RCC) events.

The proposed evolutionary scenario for the Paliouras coastal lagoon is in accordance with the existing models of the sea level rise in the Aegean coastal areas concerning the time span before 4000 yr BP and the mid-late Holocene climate events.

yr BP sediment record in order to explore the impact of Holocene climate evolution on silicon cycling.

Motivated by the didactic interest of the theme, this review sought to recompose scientific knowledge and debate on hypotheses, models of Holocene climate evolution and interpretations of possible causes.

Discrete phases of high or low flooding influence are recognised, and these correspond with large-scale Holocene climate history.

Although extensive archeological research works have been conducted in the Serteya region in recent years, the Holocene climate history in the Western Dvina Lakeland in Western Russia is still poorly understood.
