  1. 1. 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

  3. 2. Paleoclimate perspective on Earth's climate sensitivity and feedbacks

    Författare :Martin Renoult; Thorsten Mauritsen; Navjit Sagoo; Masa Kageyama; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Paleoclimate; Climate sensitivity; Climate feedbacks; Last Glacial Maximum; Pliocene; Snowball Earth; Emergent constraint; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Sammanfattning : The addition of carbon dioxide (CO2) in the atmosphere due to human activities is the main driver of global warming. How much the Earth will warm in the future is often represented by the Earth's equilibrium climate sensitivity (ECS), the long-term temperature response considering the effect of climate feedbacks after an abrupt and sustained doubling of atmospheric CO2 from pre-industrial concentration.

  4. 3. Hygrothermal Simulations of Buildings Concerning Uncertainties of the Future Climate

    Författare :Vahid Nik; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mould growth; climate change; climate uncertainties; hygrothermal simulation; energy demand;

    Sammanfattning : Global warming and its effects on climate are of great concern. Climate change can affect buildings in different ways, i.e. it can change the energy demand or the moisture durability of buildings in the future. LÄS MER

  5. 4. Carbon exchange in boreal ecosystems: upscaling and the impacts of natural disturbances

    Författare :Julia Kelly; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Carbon fluxes; CH4; Climate change; CO2; Drought; Ecosystem respiration; Forest; Peatland; Remote sensing; Temperature; Thermal camera; UAV; Wildfire;

    Sammanfattning : Boreal forests and peatlands are globally significant carbon stores but they are threatened by rising air temperatures and changes in precipitation regimes and the frequency of natural disturbances. Predicting how the boreal biome will respond to climate change depends on being able to accurately model and upscale the greenhouse gas fluxes between these ecosystems and the atmosphere. LÄS MER

  7. 5. Essays on heterogeneity and uncertainty in climate policy and development

    Författare :Tsegaye Ginbo Gatiso; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This thesis consists of four papers focusing on the role of heterogeneity and uncertainty in the context of climate change policy and agricultural development. By using intra-household data, the first paper illustrates differences in spouses’ perception of climatic risks and its effect on household’s adoption of climate change adaptation in sub-Saharan Africa.
