  2. 16. Life-Cycle Energy and Carbon Implications of Wood-Based Products and Construction

    Author : Roger Sathre; Leif Gustavsson; Birger Solberg; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest products; climate change mitigation; carbon balance; energy; life cycle; wood; land use; Environmental engineering; Miljöteknik;

    Abstract : Forests can be an important element of an overall strategy to limit the atmospheric concentration of carbon dioxide (CO2) that contributes to climate change. As an integral part of the global carbon cycle, forests remove CO2 from the atmosphere as they grow, and accumulate carbon in tree biomass. READ MORE

  4. 17. Plant-soil-herbivore interactions in a high Arctic wetland - Feedbacks to the carbon cycle

    Author : Julie Maria Falk; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic wetlands; carbon balance; herbivory; increased grazing pressure; methane fluxes; muskox exclusion; substrate avalibility; vegetation composition and density;

    Abstract : Arctic ecosystems hold massive amounts of the global carbon in their soils and are of great importance for the global terrestrial exchange of greenhouse gases to the atmosphere. The arctic region has in general been acting as a C sink for the past 10000 years, however with climate change the C balance in some areas is shifting towards becoming a C source. READ MORE

  5. 18. Achieving carbon isotope mass balance in northern forest soils, soil respiration and fungi

    Author : Björn Boström; Alf Ekblad; Phil Ineson; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 13C; Carbon cycle; Ectomycorrhizal fungi; Forest soil; Microbial respiration; Soil respiration; Stable isotopes; Biology; Biologi; Biology; Biologi;

    Abstract : Northern forests contain a large part of the global terrestrial carbon pool and it is unclear whether they will be sinks or sources for atmospheric carbon if the climate warms as predicted. Stable isotope techniques provide unique tools to study the carbon cycle at different scales but the interpretation of the isotope data is impaired by our inability to close the carbon isotope mass balance of ecosystems.

  6. 19. Carbon Dioxide Supersaturation in Lakes – Causes, Consequences and Sensitivity to Climate Change

    Author : Sebastian Sobek; Lars J. Tranvik; Yves Prairie; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; carbon dioxide; boreal lakes; respiration; dissolved organic carbon; climate change; Biologi; Biology; Biologi;

    Abstract : The global carbon cycle is intimately linked with the earth’s climate system. Knowledge about carbon cycling in the biosphere is therefore crucial for predictions of climate change. READ MORE

  7. 20. Carbon Recovery in A Dual Fluidized Bed Gasifier

    Author : Sébastien Pissot; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gasification; recycling; dual fluidized bed; chemical looping gasification; circular economy; carbon recovery; biomass; plastic waste;

    Abstract : As the concept of a circular economy gains acceptance and awareness of climate change and its disastrous consequences increases, the ways in which we produce the carbon-based goods upon which so much of our economy depends need to change. Society must end its reliance on fossil carbon resources and shift to renewable sources that enable the establishment of a carbon cycle. READ MORE
