PIGS scientific goals

PIGS built on previous experience gained from the INQUA MIS 11 project, and addresses the following areas of research:

1. The timing and the duration of specific interglacials.

2. The nature and magnitude of the climate response in the marine, terrestrial and atmospheric parts of the Earth system, including spatial and temporal patterns and the presence of stability or instability.

3. The operation of the carbon cycle in marine, terrestrial and atmospheric realms.

4. Integration of the paleo-data with modeling studies.


Priority topics

The following specific priority topics were defined at the first PIGS workshop:

1. Intra-interglacial variability (temporal and spatial), abrupt climate changes and trends, including high-low latitude links;

2. Overshoots in greenhouse gases;

3. Astronomical signature, phasing of precession and obliquity;

4. Magnitude and duration of warmth on global and regional scales

5. Duration and end of interglacials;

6. Can we explain the structure of interglacials from the forcing?


Outcomes

The workshops were organized around these themes and resulted in newsletter reports, workshop report publications, the compilation of information on data, and a summary group publication at the end of the project.
