Paleo Perspectives

Paleo Perspectives describe the long-term climate record derived from paleoclimatology data for time periods that pre-date the instrumental measurements used for modern weather and climate analysis. Each piece uses the paleo record to provide insight on a societally-relevant issue, and explain the natural variability of Earth’s climate over interannual, decadal, centennial, millennial, and other time scales. Each perspective links to corresponding scientific research results and datasets.
