The International Tree-Ring Data Bank (ITRDB) is a data repository for tree ring measurements that has been maintained since 1990 by the United States' National Oceanic and Atmospheric Administration Paleoclimatology Program and World Data Center for Paleoclimatology. [1]
Paleoclimatology (British spelling, palaeoclimatology) is the scientific study of climates predating the invention of meteorological instruments, when no direct measurement data were available. [1] As instrumental records only span a tiny part of Earth's history , the reconstruction of ancient climate is important to understand natural ...
Global paleoclimate indicators are the proxies sensitive to global paleoclimatic environment changes. They are mostly derived from marine sediments.Paleoclimate indicators derived from terrestrial sediments, on the other hand, are commonly influenced by local tectonic movements and paleogeographic variations.
Reconstructions of global temperature of the past 2000 years, using composite of different proxy methods. In the study of past climates ("paleoclimatology"), climate proxies are preserved physical characteristics of the past that stand in for direct meteorological measurements [1] and enable scientists to reconstruct the climatic conditions over a longer fraction of the Earth's history.
The warm period was followed by a gradual decline, of about 0.1 to 0.3 °C per millennium, until about two centuries ago. However, on a sub-millennial scale, there were regional warm periods superimposed on this decline. [2] [3] [4] For other temperature fluctuations, see temperature record. For other past climate fluctuation, see paleoclimatology.
Palaeogeography, Palaeoclimatology, Palaeoecology ("Palaeo3") is a peer-reviewed scientific journal publishing multidisciplinary studies and comprehensive reviews in the field of palaeoenvironmental geology.
The Neotoma Paleoecology Database (Neotoma) is an open international data resource that stores and shares multiple kinds of fossil, paleoecological, and paleoenvironmental data. [1] Neotoma specializes in fossil data holdings at timescales covering the last several decades to the last several million years. Neotoma is organized and led by ...
Paleoceanography and Paleoclimatology is a peer-reviewed scientific journal published by the American Geophysical Union. It publishes original research articles dealing with all aspects of understanding and reconstructing Earth's past climate and environments from the Precambrian to modern analogs. [ 1 ]
