| Global Earth History | | A series of plate-tectonic reconstructions to show the broad patterns of Phanerozoic Earth history. |
| PAGES | | International Geosphere-Biosphere Program (IGBP) on paleoclimatology. |
| Paleoclimate Modelling Intercomparison Project | | Coordinates and encourages the systematic study of atmospheric general circulation models (AGCMs) and to assess their ability to simulate large changes of climate such as those that occurred in the distant past. |
| Paleomap | | Virtual reality reconstructions illustrating the plate tectonic development of the ocean basins and continents, as well as the changing distribution of land and sea during the past 1100 million years. |
| Pangea Coring Workshop | | Announcement and description of an international workshop on a climatic, biotic, and tectonic transect, pole-to-pole, across the early Mesozoic supercontinent, June 1999. Updated regularly. |
| The Delphi Project | | Marine sediment core data, in particular oxygen and carbon isotope data, from a variety of different locations. |
| The Paleogeographic Atlas Project | | Global paleogeography and paleoclimates, with emphasis on the Permian and Jurassic. Climate-sensitive sediment and fossil plant distributions are shown on detailed paleogeographic maps, enabling determinations of global paleoclimate patterns. | |
