1. 1. Climate, Conflict and Coping Capacity : The Impact of Climate Variability on Organized Violence

   Författare :Nina von Uexkull; Erik Melander; Hanne Fjelde; Jack A. Goldstone; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; civil conflict; communal conflict; climate change; climate variability; Sub-Saharan Africa; Kenya; geo-referenced event data; agricultural dependence; vulnerability; Peace and Conflict Research; Freds- och konfliktforskning;

   Sammanfattning : Understanding the conflict potential of climate variability is critical for assessing and dealing with the societal implications of climate change. Yet, it remains poorly understood under what circumstances – and how – extreme weather events and variation in precipitation patterns affect organized violence. LÄS MER

3. 2. Impact of Climate Change on Extreme Events: Insights from Asia and Scandinavia

   Författare :Dong An; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Climate change; extreme events; precipitation extremes; droughts; climate variability; ENSO; climate model; climate projection; the Asia-Pacific region; scandinavia;

   Sammanfattning : As climate has warmed significantly over past decades, numerous studies have confirmed a pattern of more frequent and more intense hydro-climate events across the globe, such as floods, heatwaves, and droughts. Analyzing the variability of climate events with reliable historical data records is one of the most direct approaches for understanding its patterns of change. LÄS MER

4. 3. Understanding West African Monsoon Variability : Insights from Paleoclimate Modelling of Past Warm Climates

   Författare :Ellen Berntell; Qiong Zhang; Alessandra Giannini; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; West African Monsoon; Monsoon Variability; Paleoclimate; Climate modelling; naturgeografi; Physical Geography;

   Sammanfattning : The Sahel, a water-vulnerable region in West Africa, relies heavily on rainfed agriculture. The region experienced pronounced droughts during the 20th Century, emphasising the socio-economic importance of understanding the drivers of the rainfall variability. LÄS MER

5. 4. Holocene environmental changes and climate variability in the Eastern Mediterranean : Multiproxy sediment records from the Peloponnese peninsula, SW Greece

   Författare :Christos Katrantsiotis; Stefan Wastegård; Rienk Smittenberg; Jan Risberg; Elin Norström; Sherilyn Fritz; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mediterranean; Greece; Peloponnese; Holocene; sediments; diatoms; n-alkanes; stable isotopes; tectonics; climate variability; monsoons; NAO; NCP; Physical Geography; naturgeografi;

   Sammanfattning : This thesis presents multiproxy reconstructions of the mid to late Holocene climate and environmental changes in the Peloponnese peninsula, SW Greece. The combined dataset consists of diatom, biomarker and X-ray fluorescence spectrometry (XRF) elemental data in radiocarbon-dated sediment cores taken from the Agios Floros fen and the Gialova Lagoon in SW Peloponnese and the Ancient Lake Lerna in NE Peloponnese.

7. 5. Water resources in Iceland - Impacts of climate variability and climate change

   Författare :Jona Finndis Jonsdottir; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; marklära; pedology; cartography; climatology; Fysisk geografi; geomorfologi; geomorphology; runoff map; projection of future runoff; Environmental studies; Miljöstudier; Physical geography; hydrological modelling; trends; climate change; climate variability; Iceland; water resources; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik; kartografi; klimatologi; Civil engineering; hydraulic engineering;

   Sammanfattning : Hydropower is the main source of electricity production in Iceland. In 2005, 80.8% of all electricity was generated by hydropower (7015 GWh). Hydropower production is affected both by variations and changes in discharge. LÄS MER
