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. Global warming is one symptom of the much larger problem of human-caused climate change.

These resources explain how scientists study past climate, demonstrate the value of paleoclimatology in climate change science, and provide images and illustrations of paleoclimatology research. Join the forum for discussions and announcements, including employment opportunities, among paleoclimatologists throughout the world at the Paleoclimate Discussion List. More Information. 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.

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.
