1. Short-Time Temporal Changes of CH4 Fluxes in Different Tropical Tree Species : In-situ research regarding methane emissions from inundation-adapted Amazonian tree species in Jardim Bot�nico do Rio de Janeiro.
Kandidat-uppsats, Linköpings universitet/Tema MiljöförändringSammanfattning : Methane (CH4) is guaranteed to affect climate change and is essential in rising temperatures. Scientists have known for over two decades that wetlands emit CH4 to such an extent that it affects our climate. Tropical trees that grow in wetlands tend to emit or act as a conduit of CH4, to the extent that it has a negative environmental impact. LÄS MER
2. Methane and Carbon Dioxide Emissions From Three Smallscale Hydropower Stations in South of Sweden
M1-uppsats, Linköpings universitet/Tema MiljöförändringSammanfattning : Over the past decades, evidence show that the anthropogenetic greenhouse gases (GHG) emissions of carbon dioxide (CO₂) and methane (CH₄) are the main drivers behind global warming and are becoming stronger. Globally, hydropower is among the main sources of renewable energy and the popular notion that hydropower electricity is carbon neutral has been under debate as evidence from measurements in different regions of the globe show significant and highly variable carbon emissions from hydropower reservoirs.

3. Greenhouse gas emissions from three large lakes during the autumn 2020
Kandidat-uppsats, Linköpings universitet/Institutionen för temaSammanfattning : Methane (CH4) and carbon dioxide (CO2) are two greenhouse gases and main drivers of global climate change. Lakes are known to be a source of CH4 and CO2 to the atmosphere. While the importance of these emissions is clear, their magnitudes and regulation are still uncertain due to the scarcity of flux measurement data from lakes. LÄS MER
4. Variability of summer CH4 and CO2 flux rates in and between three large Swedish lakes : A spatio-temporal field study
Kandidat-uppsats, Linköpings universitet/Tema MiljöförändringSammanfattning : Understanding of natural greenhouse gas (GHG) cycles is crucial for making GHG budgets, which work as basis in climate change and global warming policy programs. Lakes as a source for GHG activity have only recently been included in global GHG budgets, and most studies of lake GHG flux rates are conducted on lakes <10 km2, which only comprise roughly half of the global lake area—making data of large lake flux rates scarce.

5. Knowledge and Data Driven Approaches for Hydrocarbon Microseepage Characterizations: An Application of Satellite Remote Sensing
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Methane is a potent greenhouse gas that plays a major role in climate change. Significant uncertainty exists in the estimates of emissions from natural methane sources. This uncertainty in data is one of the primary scientific challenges in climate model. LÄS MER
