The PAGES/CLIVAR Intersection -- Workshop Summary |
|
The instrumental and satellite record of climate variability is too
short and spatially incomplete to reveal the full range of seasonal to
centennial-scale climate variability, or to provide empirical examples of
how the climate system responds to large changes in climate forcing. This
recent record is also a complex reflection of both natural and anthropogenic
forcing (e.g., trace gas and aerosol). The paleoclimatic record from varied
proxy sources, on the other hand, provides the much wider range of
realizations needed to describe and understand the full range of natural
climate system behavior. The need for an improved paleoclimate perspective is highlighted in the recently produced Science Plan of the World Climate Research Programme (WCRP) Climate Variability and Predictability (CLIVAR) Programme, as are the merits of joining forces with the International Geosphere-Biosphere Programme (IGBP) Past Global Changes (PAGES) Core Project to meet the paleoclimatic needs of CLIVAR.To determine the extent of intersection between CLIVAR and PAGES, and to begin a productive interdisciplinary collaboration among scientists belonging to these two separate research communities, a joint IGBP-WCRP workshop was held. This workshop brought together members of both the CLIVAR and PAGES communities, and defined specific foci where paleoclimatic research would feed directly into a better understanding of climate variability and predictability. These proposed foci cut across the traditional seasonal-interannual and decadal-centennial time-scales of CLIVAR GOALS (Global Ocean Atmosphere Land System), CLIVAR DEC-CEN (Decade- to Century-scale climate variability) and CLIVAR-ACC (Anthropogenic Climate Change), and center on the
