  4. 2. Late Quaternary climate and environmental change in the summer rainfall region of South Africa : A study using trees and wetland peat cores as natural archives

    Author : Elin Norström; Karin Holmgren; Michael Meadows; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; paleoclimate; Late Quaternary; pollen; stable isotopes; diatoms; phytoliths; dendroclimatology; South Africa; Physical geography; Naturgeografi; Physical Geography; naturgeografi;

    Abstract : This thesis contributes with information on past climate and environmental changes in South Africa’s summer rainfall region. The study is based on multi-proxy analyses on wetland peat cores and analyses of stable isotope composition (δ13C, δ18O) and wood anatomy in cross sections from subtropical trees (Breonadia salicina).

  5. 3. Spatiotemporal climate and atmospheric circulation variability in Asia inferred from tree rings

    Author : Andrea Seim; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Asia; atmospheric circulation; Central Asia; dendroclimatology; growth-climate relationship; objectively classified weather types; teleconnections; tree-ring networks;

    Abstract : Observed 20th century warming trends accompanied by more frequent weather extremes such as droughts or intense rainfall events have consequences for societies and environments alike. In Asia, where the majority of the population depend on agricultural productivity, recent climate change is likely to increase societal hardships. READ MORE

  6. 4. Summer Climate Variability during the Past 1200 Years in Central Scandinavia – A Tree-Ring Perspective

    Author : Peng Zhang; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Central Scandinavia; climate variability; dendroclimatology; maximum latewood density; Medieval Climate Anomaly; model-proxy data comparison; Pinus sylvestris L.; temperature; tree-ring width;

    Abstract : To set the current 20th century warming in a long-term context, significant efforts have been made to reconstruct hemispheric-to-global temperatures beyond the instrumental period. Tree-rings, which have annual resolution and can be precisely dated, have been widely used to infer past climate variability. READ MORE
