Dissolved organic carbon (DOC) plays an essential role in the biogeochemistry and ecology of surface waters by influencing carbon cycle and microbial respiration. DOC is related to CO2 emissions from inland waters that can be compared to emissions of peatlands and DOC decay is influenced by environmental factors. Traditional methods used to measure DOC decay do not account for environmental factor

Global climate goals such as the United Nations 2030 Agenda and the Paris Agreement are formulated at the international level but are primarily implemented through national, regional and local governance. This thesis examines how global climate goals are translated and implemented across governance levels, from the UN to municipal physical planning, using the urban development area Södra Hyllie in

In response to rapid climate change and increasing human pressure, a wide variety of taxa have shifted their distribution in the past decades (range shift), with important consequences for ecosystem services and human health and economy. However, it is not yet clear whether most species will be able to track their favourable habitats or lag behind the climate signal (migration lag). Studying the p

Under the global carbon neutrality agenda, emission reduction in China’s heavy-duty transport sector is becoming urgent, though the transition faces multiple barriers. Despite China’s leading position in new energy heavy-duty trucks, gaps remain at the strategic and policy levels. This thesis, based on the Multi-Level Perspective (MLP) and Policy Challenge theory, uses policy content analysis, hot

For many years, fascism in East Central and Southeastern Europe remained an overlooked aspect of the history of transnational and transatlantic fascism. This introduction provides a background on how this came to pass and why we should rethink this assumption. The introduction explains how the heterogeneity of East Central and Southeastern European fascism alters the general understanding of Europ

En majoritet av de nordliga torvmarkerna utvecklades under holocen som ett resultat av en positiv massbalans mellan nettoprimärproduktion och heterotrofa nedbrytningshastigheter. Sedan dess har de lagrat stora mängder kol i terrestra ekosystem. En betydande del av dessa områden sammanfaller också med regioner med underliggande permafrost och uppvisar olika ackumulationsmönster av torv. Således, föThe majority of the northern peatlands developed during the Holocene as a result of a positive mass balance between net primary productivity (NPP) and heterotrophic decomposition rates. Over that time they have sequestered a huge amount of carbon in terrestrial ecosystems. A significant proportion of these areas also coincides with areas underlain with permafrost and shows a diverse range of peat

This study investigates the effects of temperature and relative humidity (RH) on the formation of secondary organic aerosol (SOA) from Δ3-carene, a prevalent monoterpene in boreal forests. Dark ozonolysis experiments of 10 ppb Δ3-carene were conducted in the Aarhus University Research on Aerosol (AURA) atmospheric simulation chamber at temperatures of 0, 10, and 20 °C. Under dry conditions (RH < 2

The remote forcing from land surface changes in the Sahara is hypothesized to play a pivotal role in modulating the intensity of the East Asian summer monsoon (EASM) through ocean-atmospheric teleconnections. This modulation has far-reaching consequences, particularly in facilitating societal shifts documented in northern China. Here, we present a well-dated lake-level record from the Daihai Lake

Atmospheric mineral dust not only interacts with the climate system by scattering incoming solar radiation and affecting atmospheric photochemistry, but also contributes critical nutrients to marine and terrestrial ecosystems. In a high-resolution analysis of paleodust deposition, peat development and soil dust sources, we assess the interplay between dust deposition and bog development of the Dav

During solar storms, large amounts of solar energetic particles (SEP) are accelerated into the interplanetary medium and sometimes hit Earth. These events, known as SEP events, can have harmful impacts on our modern society by affecting spacecrafts and potentially astronauts in space. The first directly observed solar storm was the Carrington event in 1859 which is linked to disruptions of the tel

We present a cognitive semiotic case study of the narrative potential of the statue Den lille Havfrue (‘the little mermaid’) by Edvard Eriksen in Copenhagen. On the basis of theoretical analysis and a survey in which 20 European and 19 Chinese participants replied to questions concerning this statue we argue that it, and similar statues, may be considered as products of intersemiotic translation,

Arctic and subarctic areas have experienced a rapid warming and substantial increases in precipitation in recent decades. The frequency and intensity of some extreme events, such as fires, winter warming events, extreme rainfall, and droughts, has also increased. These climatic changes and other anthropogenic factors have caused profound changes in arctic and subarctic ecosystems with important im

Interannual variability of the terrestrial ecosystem carbon sink is substantially regulated by various environmental variables and highly dominates the interannual variation of atmospheric carbon dioxide (CO2) concentrations. Thus, it is necessary to determine dominating factors affecting the interannual variability of the carbon sink to improve our capability of predicting future terrestrial carb

In this two-part paper, influences from environmental factors on lightning in a convective storm are assessed with a model. In Part I, an electrical component is described and applied in the Aerosol-Cloud model (AC). AC treats many types of secondary (e.g., breakup in ice-ice collisions, raindrop-freezing fragmentation, rime splintering) and primary (heterogeneous, homogeneous freezing) ice initia
