Paleoclimatology is the study of climate prior to the widespread availability of records of temperature, precipitation, and other instrumental data, using proxy data to study ancient climates. Paleoclimatologists have used proxy data to learn about Earth's climate history , including evidence of ancient droughts. What is Paleoclimatology? Perspectives Index. Images and documentation provide historical information on a variety of paleoclimatology subjects, including ice ages, tree rings, ice cores, coral reefs, and more. Paleo Image Library.

Fossil fuels are the only source of carbon dioxide large enough to raise atmospheric carbon dioxide amounts so high so quickly. The most comprehensive database ever assembled of paleoclimate proxies that tell scientists about temperatures since the last ice age ended around 12, years ago has been released to the public. Earth has warmed in the past due to changes in the Sun, volcanic eruptions, and naturally occurring increases in greenhouse gases. Our ability to understand and explain past changes is one reason we are confident that recent changes are due to humans. Today's global warming is happening at a much faster rate today than it did in the warm periods between ice ages over the last million years. Paleoclimate records show that while there have been several periods over the past 1, years when sea ice extents expanded and contracted, the decrease during the modern era is unrivaled.

NCEI manages the world's largest archive of climate and paleoclimatology data. Our mission is to preserve and make this data and information available in order to understand and model environmental variability on an interannual to millennial time scale. The Paleoclimatology team operates the World Data Service for Paleoclimatology and an Applied Research Service for Paleoclimatology, and partners with national and international science initiatives around the world to expand the use of paleoclimatology data. Paleoclimatology data are derived from natural sources such as tree rings, ice cores, corals, stalagmites, and ocean and lake sediments. These proxy climate data extend the weather and climate information archive by hundreds to millions of years. The data include geophysical or biological measurement time series and some reconstructed climate variables such as temperature and precipitation. Scientists use paleoclimatology data and information to understand natural climate variability and future climate change.

Coral data at the World Data Service for Paleoclimatology include stable isotope and trace metal analyses from corals located around the globe. Corals provide proxy data for upper ocean environment parameters such as sea surface temperature and salinity throughout the past several centuries.
