Federal government websites often end in. The site is secure. The World Data Service for Paleoclimatology archives climate model input and output files. Efforts to understand past climate and predict future climate change rely on computer climate models that include the physical processes of the climate system. Model datasets archived by the World Data Service enable rigorous comparisons between numerical simulations and paleoclimatology data. Launch Paleo Models Data Search.

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.

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.

Home National Oceanic How is the current global warming trend different from previous warming periods in Earth's history? Natural variability can explain much of Earth's average temperature variation since the end of the last ice age, but over the past century, global average temperature has risen from near the coldest to the warmest levels in the past 11, years. Download Metadata. See metadata information for parameter and study location details. If this work was prepared by an officer or employee of the United States government as part of that person's official duties it is considered a U. Fossil fuels are the only source of carbon dioxide large enough to raise atmospheric carbon dioxide amounts so high so quickly. The site is secure. What's the difference between global warming and climate change? Why on Earth are climate scientists so interested in the West Antarctic ice sheet?

Katherine Allen studies oceans and climate, past and present. Her knowledge of plankton and her scuba diving skills have allowed her to explore fascinating and beautiful locations from New Zealand to Maine. 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.
