  2. 1. Modelling regional climate-vegetation interactions in Europe : A palaeo perspective

    Author : Gustav Strandberg; Erik Kjellström; Qiong Zhang; Johan Nilsson; Hans Renssen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Palaeoclimate; climate model; vegetation; vegetation changes; land-cover; changes; proxy data; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Studies in paleoclimate are important because they give us knowledge about how the climate system works and puts the current climate change in necessary perspective. By studying (pre)historic periods we increase our knowledge not just about these periods, but also about the processes that are important for climatic variations and changes. READ MORE

  4. 2. High-resolution simulations of two cold palaeo climates in Europe : MIS 3 and LGM

    Author : Gustav Strandberg; Erik Kjellström; Qiong Zhang; Johan Nilsson; Anders Moberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Palaeo climate; climate modelling; proxy data; LGM; MIS 3; meteorologi; Meteorology;

    Abstract : The study of past climate is important because it increases our understanding of how the climate system works. Past climate is often reconstructed by using proxies (that is observations of things that tell something about past climate, for example tree rings, pollen in lake sediments and fossils). READ MORE

  5. 3. Asian monsoon over mainland Southeast Asia in the past 25 000 years

    Author : Akkaneewut Chabangborn; Barbara Wohlfarth; Karen Kohfeld; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Asian monsoon; ITCZ; palaeo-vegetation; palaeoclimate; lake sediment; Last Glacial Maximum; Holocene; Marine Geoscience; marin geovetenskap;

    Abstract : The objective of this research is to interpret high-resolution palaeo-proxy data sets to understand the Asian summer monsoon variability in the past. This was done by synthesizing published palaeo-records from the Asian monsoon region, model simulation comparisons, and analysing new lake sedimentary records from northeast Thailand. READ MORE

  6. 4. Studies on Tropical Palaeo-variation in Climate and Cosmic Ray Influx : Geochemical data from stalagmites collected in Tanzania and northern South Africa

    Author : Katarina Lundblad; Karin Holmgren; Augusto Mangini; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; palaeoclimatology; cosmic ray influx; stalagmites; Earth sciences; Geovetenskap;

    Abstract : The main aims of this project were to contribute to the knowledge about tropical climate variations, and to investigate the possibilities of obtaining cosmic ray influx data from stalagmites.Stalagmites from Tanzania and northern South Africa were palaeoclimatologically analysed.

  7. 5. The development and implementation of software for palaeoenvironmental and palaeoclimatological research : the Bugs Coleopteran Ecology Package (BugsCEP)

    Author : Philip Buckland; Roger Engelmark; Geoffrey Lemdahl; Paul Sinclair; Umeå universitet; []
    Keywords : HUMANIORA; HUMANITIES; Quaternary geology; environmental archaeology; quaternary science; Coleoptera; beetles; database; environmental reconstructions; climate reconstructions; software; Mutual Climatic Range; MCR; palaeoentomology; Kvartärgeologi; Archaeology; Arkeologi; Archaeology; arkeologi;

    Abstract : This thesis documents the development and application of a unique database orientated software package, BugsCEP, for environmental and climatic reconstruction from fossil beetle (Coleoptera) assemblages. The software tools are described, and the incorporated statistical methods discussed and evaluated with respect to both published modern and fossil data, as well as the author’s own investigations.
