To learn more about this topic, visit the following web sites:


Direct Records and Proxies

Proxy Climatic Data, NOAA Paleoclimatology Program
This site lists and describes the widely-used proxy climate data types.

Paleoclimates and Pollen
On this web site, information is offered on the background, trends, and evidence of paleoclimates.

Fossil Pollen

Fossil Pollen of the Colorado Plateau, Northern Arizona University
Learn why fossil pollen is a useful tool for determining paleoclimates.

Fossil Groups: Spores and Pollen, USGS
Learn how pollen can yield records of vegetation and community changes over time by exploring this site.
