1. 1. Minskning av palsmyrar som resultat av klimatförändringar i norra Sverige mellan 1960–2020

   Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :My Apelkvist; [2023]
   Nyckelord :palsmyrar; palsar; norra Sverige; carbon feedback; klimatförändringar;

   Sammanfattning : The climate is changing at a rapid rate. This causes both an increase in temperature and precipitation in the northern high latitudes. Subarctic peatlands contain 30% of the carbon storage in the northern permafrost zone. LÄS MER

3. 2. Evaluating DInSAR for measuring seasonal elevation dynamics at the Vissátvuopmi palsa mire complex in Northern Sweden

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :André Farjami; [2022-09-09]
   Nyckelord :;

   Sammanfattning : During recent years the palsa mires of Fennoscandia have reported to be undergoing extensive lateral degradation, and in a warming environment the palsa mires of Sweden among others are threatened to thaw completely by the end of this century. Since subarctic peatlands account for 30% of the global soil organic carbon storage, small degradation changes in these areas globally, can potentially change the greenhouse gas emissions on a worldwide scale.

4. 3. The potential impact of changing vegetation on thawing permafrost : effects of manipulated vegetation on summer ground temperatures and soil moisture in Abisko, Sweden

   Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Eric Torkelsson; John Bengtsson; [2012]
   Nyckelord :vegetation manipulation experiment; permafrost; climate change; physical geography; geography; Abisko; sub-arctic; naturgeografi; geografi; klimatförändring; manipulation av vegetation; subarktis; Earth and Environmental Sciences;

   Sammanfattning : The Arctic region has experienced significant warming in the past decades and according to predictions further increases in air temperatures and precipitation will occur during the 21st century. Recent changes in climate have had widespread implications for the permafrost around the Arctic. LÄS MER

5. 4. Degrading palsa mires in northern Europe : changing vegetation in an altering climate and its potential impact on greenhouse gas fluxes

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Julia Karlgård; [2008]
   Nyckelord :geography; physical geography; palsa mires; northern Europe; greenhouse gas fluxes; Earth and Environmental Sciences;

   Sammanfattning : The on-going global warming is projected to have large impacts on the arctic and subarctic environment. Especially vulnerable are ecosystems with narrow climatic envelopes and with small possibilities of adaptation. An example of this is the palsa mires, subarctic mire complexes with patches of permafrost. LÄS MER
