16. A remote-sensing approach to studying drought resistance in Swedish old-growth and production forests
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Boreal forest ecosystems are predicted to experience hotter and drier summers due to climate change, leading to more frequently reduced soil water availability and an increased risk of droughts, as was already the case in Northern Europe during the severe summer drought of 2018. Prolonged water stress in forest ecosystems can lead to impacts ranging from reduced photosynthesis to forest dieback. READ MORE

17. Linking Jet Stream Variability and the NAO to the Terrestrial Carbon Cycle in Europe
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The terrestrial carbon cycle is a part of the global carbon cycle, where one important component is the terrestrial vegetation. Terrestrial vegetation largely controls the land surface carbon exchanges and leverage the atmospheric greenhouse gas concentrations, significantly affecting the trajectory of global warming.
