Caption: Paleoscience provides data against which to test the performance of climate models run under past boundary conditions different from those that prevail at the present day. This figure shows a first-stage comparison between model simulations and lake level data for the period 6000 years before present. Attention is focused on the Sahara/Sahel region of Africa. There is quite good agreement between models over this area, but all fail to simulate the strong positive hydrological balance demonstrated by the paleo lake level data. This initial mismatch has led to a fruitful interaction between data and modeling communities out of which is emerging a better understanding of the sensitivity of models, and of the climate systems which they represent, to changes in vegetation, land cover and surface moisture.

Science and implementation plans for the PANASH focus (Paleoclimate and Environments of the Northern and Southern Hemispheres). The aim of the PANASH focus was to reconstruct climate and environments of the past, using a multiproxy data and modeling approach, along three Pole-Equator-Pole (PEP) terrestrial transects: PEP I: The Americas Transect, PEP II: The Austral-Asian Transect, PEP III: The Afro-European Transect.

Within the context of IGBP’s objectives, an emphasis on the agricultural period, and PAGES objectives (Eddy, 1992), a planning meeting was held in Bern, Switzerland, in February 1994. This report sets out the key research recommendations of the meeting. It also includes a strategy and implementation plan.

Caption: Century scale variations in hydrologic balance reconstructed for two widely separated lakes in tropical Africa from sediment records and dated shorelines. The observed palaeohydro-logical changes imply shifts in the precipitation/evaporation balance much greater any to be found in the modern instrumental record. They show that dramatic, abrupt shifts in hydrologic balance have occurred on societally relevant timescales. Abrupt changes in the North African monsoon may have taken place in response to changes in the North Atlantic, represented here by sea surface density reconstructed from marine faunal and isotopic records in sediment cores.
