Cold Climate, Warm Climates: How Can We Tell Past Temperatures?

Gavin Schmidt, NASA Goddard Institute for Space Studies

This brief NASA article provides general information about paleoclimatology (the study of past climate). Focusing on ice core data and foraminifera (shelled marine microorganisms) in deep sea sediments, the article provides a summary of how paleoclimate can be inferred.
