Topic: Paleoclimatology


  
  Paleoclimatology - Wikipedia, the free encyclopedia
Paleoclimatology is the study of climate change taken on the scale of the entire history of the earth.
Glaciers are a widely employed instrument in Paleoclimatology.
The fossil itself is dated with radioactive dating within a wide margin of error.

 The Environmental Literacy Council - Paleoclimatology
Paleoclimatology is the study of climates in earlier periods in Earth's history.
Paleoclimatology must therefore rely on proxy measures, which are physical phenomena that record evidence of weather.
It also includes brief explanations of the process of climatic cooling, known as glaciation, and a discussion of the theory that long-term climate changes occur in response to Milankovitch Cycles, the cyclical changes in the Earth's relationship to the sun.

The ice in glaciers has hardened into an identifiable pattern, with each year leaving a distinct layer.
It is estimated that the polar ice caps have 100,000 of these layers or more.
There has been a cycle of ice ages for the past 2.2-2.1 million years (starting before the Quaternary in the late Neogene Period).

Paleoclimatology has been integrated with the Climate Change Data and Detection element.
The instrumental and satellite record of climate variability extends back in time about 130 years, and is therefore not long enough to define the full range of natural climate variability.
For this reason, NOAA implements a Paleoclimatology program that is tightly focused on using geological and biological records of past climate change to understand the complete patterns, processes and causes of natural interannual to century-scale climate variability.

 Paleoclimatology
Paleoclimatology as a discipline has expanded exponentially (as measured, for example, by the output of literature) in the last 25 years.
Knowledge of paleoclimatology is valuable in its own right, and is essential to progress in our understanding of the role of the physical environment as a force driving evolutionary and ecological change.
The most widely used method is based on variations in the oxygen isotope composition of biogenic marine carbonate, from which the broad pattern of change in marine temperatures has been reconstructed.

One of the frontiers in paleoclimatology is the role and fate of the tropics in global climate change at millennial to orbital time scales.
In particular, little is known about the relative influences and interactions of insolation at high vs. low latitudes, changes in oceanic heat transport, and remote teleconnections with large-scale and interrelated features of the climate system, such as the Asian Monsoon and the Walker Circulation (ENSO).

 D-Lib Featured Collection July 2002: NOAA Paleoclimatology Program
The study of climate change over the last thousand years indicates that global warming is real, and, furthermore, that global warming over the past few years is increasing at an unprecedented rate when compared to the warming that occurred in the previous 1200 years.
The Paleoclimatology website also serves as a portal to the WDC-A, the World Data Center for Meteorology, Asheville, which is maintained by the U.S. Department of Commerce, and the National Oceanic and Atmospheric Administration (NOAA).
The Paleoclimatology Program web site also presents Paleo Perspectives, a section of the site that deals with the subjects: Drought, designed to help educate, inform and highlight the history and importance of drought; and Global Warming.

Located on the Department of Commerce’s Boulder, Colorado campus, the NOAA Paleoclimatology Program was part of the NOAA National Environmental Satellite, Data and Information Service’s National Geophysical Data Center until the end of June, 2002, when it was realigned to become part of the NESDIS National Climatic Data Center.
At the heart of the Paleoclimatology Branch’s Web site is a robust database providing access to peer-reviewed data from the international community studying past climate change.
The paleoclimatology branch itself has branches in many parts of the world in the form of “mirror sites” that are connected with international colleagues.

 ScienceMaster - JumpStart - Paleoclimatology
Instead of instrumental measurements of weather and climate, paleoclimatologists use natural environmental (or "proxy") records to infer past climate conditions.
Paleoclimatology includes the collection of evidence of past climate conditions, as well as the investigation of the climate processes underlying these conditions.
Proxy data are data that paleoclimatologists gather from natural recorders of climate variability, for example, tree rings, ice cores, fossil pollen, ocean sediments, coral and historical data.

The CCDD paleoclimatology effort is directed at supporting the CCDD goals of producing long time series of key climate variables, analyzing these time series for information on climate trends and variability, and characterizing the natural background signal of the climate system for the purposes of detection and attribution.
For FY 2006, there will be a continuation of the research program managed by CCDD that focuses on high quality reconstructions of the climate history over the Holocene, with an emphasis on the last 2,000 years (i.e., the late Holocene).
Principal Investigators should contact the Paleoclimatology Branch of the National Climatic Data Center (NCDC) during proposal preparation to discuss the characteristics of data sets that will be produced and the appropriateness of these data for archival at NCDC.

 Principles of Paleoclimatology; ; Thomas M. Cronin
This introduction to the rapidly emerging field of paleoclimatology explains the patterns and processes in the history of the Earth's climate to answer such essential questions.
Using the geologic records of ocean and lake sediment, ice cores, corals, and other natural archives, Principles of Paleoclimatology describes the history of the Earth's climate—the ice age cycles, sea level changes, volcanic activity, changes in atmosphere and solar radiation—and the resulting, sometimes catastrophic, biotic responses.
Designed to give a fundamental background—including both history and methodology—to the discipline of paleoclimatology, this book is the first to advance our understanding of how climate change develops, how those changes are detected, and how the climate of the past can shape the climate of the future.

 Paleoclimatology
Paleoclimatology is the study of climate prior to the widespread availability of records of temperature, precipitation and other instrumental data.
NOAA is particularly interested in the last few thousand years because this is the best dated, best sampled part of the past climatic record and can help us establish the range of natural climatic variability in a period prior to global-scale human influence.

Biogeochemistry follows the cycling of elements through the spheres mediated by biological and geological processes, and especially their distribution and fluxes between reservoirs.
Paleoceanography and Paleoclimatology use the properties of sediments, ice cores, or biological material to infer past states of the ocean, atmosphere or climate.
Furthermore, other modern disciplines known collectively as Earth system science approach the entire Earth as a system in its own right, which evolves as a result of positive and negative feedbacks between constituent systems:
