Caption: Ice core data from Greenland have been used to reconstruct a normalized proxy North Atlantic Oscillation (NAO) index for the past 350 years (shaded green). The modern instrumental index is shown in blue and a 15 year running meadian of the proxy index in red. This record demonstrates the power of calibrated proxies to extend the time perspective on known modes of climate variability well beyond the instrumental record, and with annual resolution.

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.
