1. Applying LPJ-GUESS on the Arctic: A model evaluation and benchmarking study
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Warming in the Arctic occurs at a much higher rate than the global average, which has a considerable impact on the Arctic terrestrial carbon cycle. Permafrost thawing can release substantial amounts of carbon, whilst tundra shrubification and tree-line advance, on the other hand, may compensate for this. READ MORE

2. 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

3. Reviving Skellefteå
University essay from KTH/StadsbyggnadAbstract : The changes that we are seeing and anticipating are largely due to human behaviour. Arctic sea ice is at the lowest levels ever recorded. The volume of Arctic ice has decreased dramatically over the past decade. . READ MORE

4. Estimating active layer thickness at the high Arctic study site Zackenberg from remotely sensed ground subsidence
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The active layer thickness (ALT) is an indicator of permafrost thaw, which potentially leads to the release of large amounts of greenhouse gases under global warming, and thus could further amplify climate change. The thaw depth of the active layer also governs seasonal surface deformation, caused by the volume change between ice to water, which poses risks for slope stability and infrastructure foundations.

5. Analysis of the global ESA GlobPermafrost map for Scandinavia
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Due to its high vulnerability, permafrost is one of the key features studied in the field of climate change impacts. Permafrost is widespread in the Arctic region. READ MORE
