To learn more about climate proxies, visit the following web sites:

Proxy Climatic Data, NOAA Paleoclimatology Program
This site provides links for several different climate proxies including: Historical Data, Corals, Fossil Pollen, Tree Rings, Ice Cores, Ocean & Lake Sediments

Summary for Policymakers: The Science of Climate Change, Intergovernmental Panel on Climate Change (United Nations)
Review a list of facts and statistics about Greenhouse gases, anthropogenic aerosols, climate change over the past century, the evidence for human influence on global climate, future climate change, and remaining uncertainties.

Fossil Groups: Spores and Pollen, USGS
"By analyzing pollen from well-dated sediment cores collected at critical sites, it is possible to obtain high-resolution records of vegetation change with decadal-scale resolution and to document community changes over the last few centuries and millennia."
