Past Global Changes, IGBP

Project Description
Past Global Changes (PAGES) is the International Geosphere-Biosphere
Program (IGBP) Core Project charged with providing a quantitative
understanding of the Earth's past environment and defining the envelope of
natural environmental variability within which we can assess anthropogenic
impact on the Earth's biosphere, geosphere and atmosphere. In order to
permit validation of their effectiveness, models intended to predict
future environmental changes must be capable of accurately reproducing
conditions known to have occurred in the past.
PAGES seeks to obtain and interpret a variety of palaeoclimatic records to
provide the data essential for the validation of predictive climatic
models. PAGES seeks the integration and intercomparison of ice, ocean and
terrestrial palaeorecords, and encourages the creation of consistent
analytical and database methodologies within the palaeosciences.
PAGES research is divided into five focus areas with associated
activities and tasks:
Focus 1: Global Paleoclimate and Environmental Variability
Paleoclimate of the Northern and Southern Hemispheres (PANASH)
- PEP I (Pole-Equator-Pole I): The Americas Transect
- PEP II: The Austral-Asian Transect
- PEP III: Afro-European Transect
Focus 2: CLIVAR/PAGES Intersection
Focus 3: International Marine Past Global Changes (IMAGES)
Focus 4: Polar Programs
- Circum Arctic Paleoenvironments (CAPE)
- Quaternary Environment of the Eurasian North project (Queen)
- International Trans-Antarctic Scientific Expedition (ITASE)
- Antarctic Ice Margin Evolution (ANTIME)
Focus 5: Past Ecosystems Processes and
Human-Environment Interactions
- HITE (Human Impacts on Terrestrial Ecosystems)
- LUCIFS (Land Used and Climate Impacts on Fluvial Systems during the
Period of Agriculture)
- LIMPACS (Human Impact on Lake Ecosystems)
