Additional Physical Format: Online version: Evaluation of climate proxy data in relation to the European Holocene. Stuttgart: Fischer, (OCoLC) These studies have all used pollen data, which is by far the most widely available quantitative climate proxy for the Holocene period.

Most reconstructions on long-term climatic changes and proxy data are based on analysis of ice cores from Greenland and the Antarctic (Stuiver and Braziunas, ), and advances and retreats of Alpine glaciers and lake level changes (cf.

Lithology and Cited by: A vast assortment of unique Holocene proxy climate records is available from the Arctic. Developing a uniform database of proxy climate records requires a systematic approach to handle a data set based on such heterogeneous input.
The database represents an extensive search of proxy climate records published prior to November A list of other. Quaternary is composed of Pleistocene and Holocene. Pleistocene is the period that we in common language call the Ice Age.
Holocene represents the present, which basically is a Pleistocene interglacial period. Holocene is represented by the thin red line on the far left. The climate of the Holocene is the subject of this Article. In this section, we focus on multi-scale problems encountered when reconstructing palaeoclimate on the basis of terrestrial botanical proxy data (pollen and macro remains).
Climate and the taxonomical composition of the vegetation are affected and linked by complex geoprocesses acting on various spatial and temporal by: 2. The data reveal contrasting SST trends, depending upon the proxy used to derive Holocene SST history.
To reconcile these mismatches between proxies in the estimated Holocene SST trends, it has been proposed that the Holocene evolution of orbitally-driven seasonality of the incoming radiation is the first-order driving mechanism of the observed Author: Gerrit Lohmann, Ralph Schneider, Johann H.

Data: The proxy data work undertaken was focused on updating the global database for proxy-derived Holocene SST records, i.e., an SST synthesis based on alkenone-derived SST estimation, and a synthesis effort compiling the SST.
We present a new gridded climate reconstruction for Europe for the l years based on pollen data. The reconstruction is an update of Davis et al. () using the same methodology, but with a greatly expanded fossil and surface-sample dataset and more rigorous by: The Holocene geological epoch starts at the beginning of the current interglacial period ab years ago and continues to the present.
As discussed in previous posts, the current interglacial period is the fifth interglacial in the lastyears that was dominated by four intervening glacial periods each lasting ab toyears.

The number of sites analysed represents an increase of 48% compared to Davis et al. () (black dots). The climate of the Holocene. The last glacial maximum (Ice Age) ended about 15 thousand years ago.
The most recent glacial retreat is still going on. We call the current period of glacial retreat the Holocene epoch and it continues until present. This page discusses the climate changes within the Holocene Epoch or the current interglacial. Abstract. When making multi-proxy reconstructions over Holocene-long periods, an argument is presented that the elevation of the sites used and/or their elevation history must be taken into account before their proxy records (of temperature or Author: David A.

This review focuses on the develop-ment of the ‘Little Ice Age’ as a glaciological and cli-matic concept, and evaluates its current usefulness in the light of new data on the glacier and climatic variations of the last millennium and of the Holocene.
Project description. Tree-ring width is an important proxy in terms past climate and environment reconstruction. However, to date it was impossible to use the full potential of the longest tree-ring chronologies, the Central European oak chronologies, for climate research.
Here we summarize new evidence that moves this debate forward by testing both hypotheses. By comparing late Holocene responses to those that occurred during previous interglaciations (in section 2), we assess whether the late Holocene responses look different (and thus anthropogenic) or similar (and thus natural).Cited by: Delineating the climate processes governing precipitation variability in drought-prone Texas is critical for predicting and mitigating climate change effects, and requires the reconstruction of past climate beyond the instrumental record.
We synthesize existing paleoclimate proxy data and climate simulations to provide an overview of climate variability in Texas during the Holocene. The Holocene Climate Optimum (HCO) was a warm period during roughly the interval 9, to 5, years BP, with a thermal maximum around years has also been known by many other names, such as Altithermal, Climatic Optimum, Holocene Megathermal, Holocene Optimum, Holocene Thermal Maximum, Hypsithermal, and Mid-Holocene Warm Period.

Examination of ~50 globally distributed paleoclimate records reveals as many as six periods of significant rapid climate change during the time periods –, –, –, – Holocene appears as a relatively stable climatic period com-pared to the large climate ﬂuctuations during the last glacial period.
However, an examination of globally distributed high-resolution climate proxy records shows that Holocene climate variations were larger and more frequent than has been commonly recognised (Mayewski et al., ; Wan. The R package treeclim helps perform numerical calibration of proxy‐climate relationships, with an emphasis on tree‐ring chronologies.
