  1. 1. Planetary Timemaking : Paleoclimatology and the Temporalities of Environmental Knowledge, 1945-1990

    Författare :Erik Isberg; Sverker Sörlin; Sabine Höhler; Adam Wickberg; Etienne Benson; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; paleoclimatology; environmental history; temporality; ice core; deep-sea core; North Atlantic; timemaking; theory of history; planetary-scale environmental knowledge; paleoklimatologi; miljöhistoria; temporalitet; iskärna; borrkärna; Nordatlanten; tidsskapande; historieteori; planetär miljökunskap; History of Science; Technology and Environment; Historiska studier av teknik; vetenskap och miljö;

    Sammanfattning : This thesis concerns the history of paleoclimatology in the postwar period. It follows the trajectory of two climate proxy records – ice cores and deep-sea cores – in the North Atlantic region, from their emergence as scientific objects in the 1940s to their incorporation into Earth System Science in the 1980s.

  3. 2. Three essays on our planetary future

    Författare :Rasmus Karlsson; Statsvetenskapliga institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; democracy; intergenerational justice; Global change; sustainable development; innovation policy;

    Sammanfattning : This thesis propounds a techno-environmentalist position. Seeking to combine the need for natural restoration with human development, the thesis explores to what extent more radical forms of ecological modernization can offer a basis for political compromise and open new paths to global long-term sustainability.

  4. 3. Meaning and Action in Sustainability Science : Interpretive approaches for social-ecological systems research

    Författare :Simon West; Lisen Schultz; Lorrae van Kerkhoff; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Meaning; interpretive; social-ecological system; complexity; science-policy interface; transformation; sustainability science methodology; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : Social-ecological systems research is interventionist by nature. As a subset of sustainability science, social-ecological systems research aims to generate knowledge and introduce concepts that will bring about transformation. Yet scientific concepts diverge in innumerable ways when they are put to work in the world. LÄS MER

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

    Författare :Arne Tobian; Johan Rockström; Sarah Cornell; Ingo Fetzer; Dieter Gerten; Martin Volk; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. Turbulence-Assisted Planetary Growth : Hydrodynamical Simulations of Accretion Disks and Planet Formation

    Författare :Wladimir Lyra; Nikolai Piskunov; Thomas Henning; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; accretion; accretion disks; hydrodynamics; instabilities; methods: numerical; solar system: formation; planets and satellites: formation; magnetohydrodynamics MHD ; turbulence; diffusion; stars: planetary systems: formation; Astronomy and astrophysics; Astronomi och astrofysik;

    Sammanfattning : The current paradigm in planet formation theory is developed around a hierarquical growth of solid bodies, from interstellar dust grains to rocky planetary cores. A particularly difficult phase in the process is the growth from meter-size boulders to planetary embryos of the size of our Moon or Mars. LÄS MER
