1. 26. Greenhouse gas emission from tropical reservoirs : Spatial and temporal dynamics

   Författare :Annika Linkhorst; Sebastian Sobek; Frédéric Guérin; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; methane; carbon dioxide; climate; carbon cycle; lake; limnology; inland water;

   Sammanfattning : The emission of methane (CH4) and carbon dioxide (CO2) from reservoirs has been estimated to make up for about 1.3% of the global anthropogenic greenhouse gas emission. The impoundment of a river leads to the accumulation of sediment that is brought in from inflowing rivers, and the sediment organic matter is degraded to CH4 and CO2. LÄS MER

3. 27. Constructing Safety: Influence of Safety Climate and Psychological Climate on Safety Behaviour in Construction Industry

   Författare :Susanna Larsson; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; safety performance; safety climate; organisational climate; construction industry; safety behaviour; occuopational safety; accident prevention; psychological climate;

   Sammanfattning : Although, significant progress has been made in improving occupational safety in construction industry the number of deaths and injuries are still unacceptably high. In the recent years, extensive research on safety climate, part of the organisational climate research body, has been perfromed. LÄS MER

4. 28. Comparing Climate Forcers on a Common Scale

   Författare :Erik Sterner; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spatial-temporal Optimization; Carbon Cycle; Greenhouse Gases; Short-lived Climate Forcers; Upwelling-Diffusion; Metric; Energy Balance; Sea Level Rise; Non-cooperative Nash Equilibrium; Resource Extraction;

   Sammanfattning : The climate is changing at a rapid pace. Through the United Nations Framework Convention on Climate Change (UNFCCC), the world has agreed to hold the on-going temperature increase below 2 °C. Climate change is caused by emissions of different atmospheric species (climate forcers). LÄS MER

5. 29. Modelling impact climate-related change on the thermal responses of lakes

   Författare :Ana I. Ayala; Donald C. Pierson; Stéphane Goyette; Andreas Lorke; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Modelling; climate change; lakes; thermal structure; surface heat fluxes; extreme events;

   Sammanfattning : In response to climate-related changes, lakes worldwide have experienced warmer surface water temperatures, shorter ice cover periods and changes in lake stratification. As these aspects of lake dynamics exert substantial control over nutrient availability, oxygenation and biogeochemical cycling, predicting changes in lake water temperature and stratification dynamics can improve our understanding of the consequences of warming on lake ecosystems.

7. 30. Rooting for forest resilience : Implications of climate and land-use change on the tropical rainforests

   Författare :Chandrakant Singh; Ingo Fetzer; Lan Wang-Erlandsson; Ruud van der Ent; Axel Kleidon; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate change; forest dynamics; human influence; land-use change; rainforest tipping; remote sensing; resilience; root zone storage capacity; tropical forests; vetenskap om hållbar utveckling; Sustainability Science;

   Sammanfattning : Tropical rainforests in the Amazon and Congo River basins and their climate are mutually dependent. Evaporation from these forests help regulate the regional and global water cycle. Furthermore, these rainforests themselves depend on precipitation to sustain their structure and functions. LÄS MER
