6. The application of low-cost sensors in estimates of greenhouse gases : A field study at a wastewater treatment plant
University essay from Linköpings universitet/Filosofiska fakulteten; Linköpings universitet/Tema MiljöförändringAbstract : Anthropogenic activity has caused increased concentrations of greenhouse gases (GHGs) in the atmosphere which has resulted in global warming gaining momentum. GHG emission estimates up to date are insufficient and in order to mitigate GHG emissions of anthropogenic origin fluxes of GHGs need to be mapped. READ MORE

7. Evaluation of the LPJ-GUESS crop model under ambient and elevated CO2 concentrations.
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : In the future atmospheric CO2 concentrations might exceed 550 ppm according to the RCP8.5 scenario by mid-century from our current 410 ppm, while our world population is projected to surpass the 9.7 billion threshold within the same time span. This challenge leads to the raising of questions addressing future food security. READ MORE

8. Tundra carbon cycling in relation to sea-ice decline in a warming Arctic
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : We set out to investigate whether arctic tundra acted as a sink or source of carbon dioxide (CO2) between 1980-2014 and to relate changes in the net carbon balance to Arctic sea-ice decline. We want to understand how climate change and arctic warming influence arctic carbon cycling. READ MORE

9. Växthusgasflöden från restaurerad torvmark : en jämförelse mellan en restaurerad torvtäkt och en orörd myr i Store Mosse nationalpark 7 år efter återvätning
University essay from SLU/Dept. of Soil and EnvironmentAbstract : Den globala uppvärmningen ökar. För att dämpa denna ökning behöver världens växthusgasutsläpp minska. När torvmarker dikas ut för industrier går de från att vara kolsänkor till att vara kolkällor. För att få tillbaka torvmarkers funktion som kolsänka restaureras dem, främst genom återvätning.

10. Influence of permafrost disintegration on wetland carbon fluxes in Abisko, Sweden
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The northern permafrost regions are experiencing a rapid warming as surface temperatures are rising, causing a disintegration of permafrost and a deepening of the active layer (AL). This releases previously frozen carbon, making it available for decomposition by microbes. READ MORE
