  2. 11. Deglacial impact of the Scandinavian Ice Sheet on the North Atlantic climate system

    Author : Francesco Muschitiello; Barbara Wohlfarth; Raimund Muscheler; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; climate; North Atlantic; last deglaciation; isotope geochemistry; chronology; climate modeling; Marine Geology; maringeologi;

    Abstract : The long warming transition from the Last Ice Age into the present Interglacial period, the last deglaciation, holds the key to our understanding of future abrupt climate change. In the last decades, a great effort has been put into deciphering the linkage between freshwater fluxes from melting ice sheets and rapid shifts in global ocean-atmospheric circulation that characterized this puzzling climate period.

  4. 12. Entering the dynamic risk space : Assessing planetary boundary interactions through process-based quantifications

    Author : Arne Tobian; Johan Rockström; Sarah Cornell; Ingo Fetzer; Dieter Gerten; Martin Volk; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Planetary boundaries; climate change; land-use change; Earth system interactions; ecosystem modeling; green water; vetenskap om hållbar utveckling; Sustainability Science;

    Abstract : The planetary boundaries framework is an effort to define a safe operating space for humanity. Its rationale is that sustainable development needs to be achieved in ways that safeguard the stability of the Earth system on which human prosperity relies. READ MORE

  5. 13. Changes in the Freshwater System : Distinguishing Climate and Landscape Drivers

    Author : Fernando Jaramillo; Georgia Destouni; Zbigniew W. Kundzewicz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Budyko; evapotranspiration; freshwater; hydrology; hydroclimatic change; landscape change; land use; observation data; runoff; separation; water partitioning; water storage change; water use; worldwide; Physical Geography; naturgeografi;

    Abstract : Freshwater is a vital resource that circulates between the atmosphere, the land and the sea. Understanding and quantifying changes to the partitioning of precipitation into evapotranspiration, runoff and water storage change in the landscape are required for assessing changes to freshwater availability.

  6. 14. Essays on Economic Modeling of Climate Change

    Author : Gustav Engström; John Hassler; Michael Hoel; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; climate change; economic growth; energy balance models; sustainability; Economics; nationalekonomi;

    Abstract : Structural change in a two-sector model of the climate and the economy introduces issues concerning substitutability among goods in a two-sector economic growth model where emissions from fossil fuels give rise to a climate externality. Substitution is modeled using a CES-production function where the intermediate inputs differ only in their technologies and the way they are affected by the climate externality. READ MORE

  7. 15. Modeling lichen performance in relation to climate : scaling from thalli to landscapes

    Author : Anna V Jonsson Čabrajić; Kristin Palmqvist; Jon Moen; Per-Anders Esseen; Mikaell Ottosson-Löfvenius; Göran Ågren; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lichen; growth; model; micro-climate; hydration; activation; photosynthesis; respiration; Terrestrial ecology; Terrestisk ekologi; ekologisk botanik; Ecological Botany;

    Abstract : Lichens can colonize nearly all terrestrial habitats on earth and are functionally important in many ecosystems. Being poikilohydric, their active growth periods are restricted to periods when the thallus is hydrated from atmospheric water sources, such as rain, fog and high relative humidity. READ MORE
