Joe Buchdahl, Copyright Atmosphere, Climate, and Environment Information Programme

This online student guide features a web-adapted discussion of paleoclimatology, the study of climate and climate change prior to the period of instrumental measurements. This section gives a broad overview of paleoclimate proxies such as shelled microorganisms in deep marine sediments (foraminifera, or forams) and ice core data. This site also includes links to other chapters in the book, also related to understanding climate change.
