  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. Surface energy exchange and land-atmosphere interactions of Arctic and subarctic tundra ecosystems under climate change

    Författare :Christian Stiegler; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Surface energy exchange; Arctic and subarctic tundra; climate change; permafrost; eddy covariance; snow cover; micrometeorology;

    Sammanfattning : The surface energy balance determines the functioning of any ecosystem on the Earth but is still poorly understood in Arctic and subarctic biomes. In a dynamic system, such as the Earth’s climate, any change in its characteristics modifies the exchange of energy, water, and greenhouse gases between the surface and the atmosphere. LÄS MER

  5. 4. 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

  7. 5. Uncertainties in tropical precipitation and radiative feedbacks under climate change

    Författare :Alejandro Uribe Cortes; Thorsten Mauritsen; Frida Bender; Caroline Muller; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Climate change; radiative feedback; tropical precipitation; tropical extreme precipitation; climate modeling; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Sammanfattning : Clouds have a significant impact on climate. They contribute to controlling the planetary energy balance, and the precipitation distribution. Global Climate Models (GCMs) designed to reproduce the state of the climate system, however, have difficulties representing clouds. LÄS MER
