Description: Das Projekt "Umweltdynamik in Vergangenheit und Gegenwart" wird vom Umweltbundesamt gefördert und von Eidgenössische Anstalt für Wasserversorgung, Abwasserreinigung und Gewässerschutz, Abteilung für Umweltphysik durchgeführt. How can the environmental conditions in the past be reconstructed and linked to the present? The restricted view of the past: An often-stated concern today is that global warming may result in higher surface air temperatures than have ever been experienced in 'the past', with unpredictable effects on the biosphere and on social and economic infrastructures in many regions of the globe. Many of us tend to have a subjective view of 'the past' in this context which is limited to the last century or so. One reason for this limited historical perspective is the fact that networks of meteorological stations delivering high-quality instrumental data have only been in existence for the last 150 years at most. In addition, comparative media reports tend to focus on a time span within 'modern human experience'. This period, lying within the subjective time horizons of most of the inhabitants of the Alpine nations, therefore makes a suitable beginning to the story of alpine palaeoclimatology. Learning how to decipher the information left behind in nature's archives: Although Homo sapiens has experienced a least three glacial episodes, some 600 generations have passed since the last Glacial and no 'tribal memories' of Ice-Age conditions remain. Only after learning how to decipher the information left behind in nature's archives, a process which did not begin until last century, did mankind begin indirectly to rediscover Alpine glacial history. This process led to the ability to put the above-mentioned short-term 'modern human experience', especially with regard to climate studies, in much longer-term perspective. Basic to any understanding of long-term climate development in the Alpine region is the so-called Glacial Theory. Three common time windows: The principal objective is to connect and reciprocally calibrate various environmental archives and their data as well as to reconstruct the long-term history of environmental changes and climatic sequences. The projects within the coordinated project concentrated their common investigations on three time windows: 1) the last 200 years, 2) transition Younger Dryas - Preboreal (ca. 10500-9500 BP), 3) transition Allerod - Younger Dryas (ca. 11500-10500 BP).
