  2. 21. Properties and analysis of dioxin-like compounds in marine samples from Sweden

    Author : Kjell Lundgren; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; planar dioxin-like compound; polychlorinated dibenzofuran; polychlorinated biphenyl; polychlorinated naphthalene; alkylated polychlorinated dibenzofuran; high-performance liquid chromatography; PX-21 carbon column; biomagnification factor; biota to sediment accumulation factor; fluxes; relative retention time; mass spectrometry; relative response factor; ultra-violet spectroscopy; Miljökemi; Environmental chemistry; Miljökemi; analytisk kemi; Analytical Chemistry;

    Abstract : Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs), and dioxin-like polychlorinated biphenyls (PCBs) have been assigned toxic equivalency factors (TEFs). These compounds are today routinely analysed with sophisticated analytical techniques. READ MORE

  4. 22. Decision Support for Emergency Response to Multiple Natural Hazards : CHALLENGES AND NEEDS

    Author : Viktor Sköld Gustafsson; Tobias Andersson Granberg; Mattias Hjerpe; Martin Waldemarsson; Margaret Mcnamee; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Global warming exceeding 1.5°C above pre-industrial levels will very likely lead to unavoidable increases of several climate hazards in the coming decades. Climate change phenomena can increase the risk of several extreme weather events, leading to risks of what is commonly considered as natural hazards, for instance landslides and forest fires.

    Abstract : This dissertation examines migrants during a time of large-scale socio-economic transformations. These changes were particularly evident in the nineteenth-century town of Sundsvall, Sweden, to which thousands of men and women moved. READ MORE

  6. 24. Paleoclimate perspective on Earth's climate sensitivity and feedbacks

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

    Abstract : 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.

    Abstract : IPCC reported in its climate change report 2013 that the atmospheric concentrations of the greenhouse gases (GHG) carbon dioxide (CO2), methane, and nitrous oxide now have reached the highest levels in the past 800,000 years. CO2 concentration has increased by 40% since pre-industrial times and the primary source is fossil fuel combustion. READ MORE
