Development of an econo-energy model and an introduction to a carbon and climate model for use in a nuclear energy analysis
… Currently, we feed our power needs with mostly carbon-based energy sources, which have an appreciable effect on the global climate. To continue advancing, society must develop alternative, low-carbon methods for energy production with both nuclear and renewable sources being complementary …

Rate-induced tipping to metastable Zombie fires
… Our hypothesis is based on a conceptual soil-carbon model subjected to realistic changes in weather and climate patterns, including global warming scenarios and summer heatwaves. Mathematically speaking, R-tipping to the hot metastable state is a nonautonomous instability, due to crossing an …

Greenhouse gas life cycle assessment of canola-derived HEFA biojet fuel in Western Canada
… Canadian Prairies were estimated using a soil carbon model. Finally, a sensitivity analysis on life cycle inputs and co-product allocation parameters was performed. Results suggested that without land use change, canola biojet fuel may provide emissions reductions of 35% to 54% compared to …

Feedback mechanism in the oceanic carbon cycle
… implemented a simple atmosphere-ocean coupled carbon cycle model which can be used as a tool to uncover the mechanisms of the interaction between the dynamics of the atmosphere-ocean system and the oceanic reservoir of CO 2 on the 101 to 103 years time scale. The atmosphere-ocean coupled model …

Spatio-Temporal Dynamics Of Phytoplankton Biomass From Ocean Color Remote Sensing And Cmip5 Model Suites
… food web, and, importantly, drive the biological carbon pump, the combination of photosynthesis, organic carbon sinking and subsurface decomposition of organic matter which effectively sequesters carbon away from the atmosphere. Our knowledge of phytoplankton activity is currently advancing fast …

Multi-scale analysis of carbon stocks and process indicators in the agro-ecosystem of Canterbury, New Zealand
Increasing interest in characterising carbon dynamics in the agricultural landscape has been driven by the clear need for greenhouse gas mitigation strategies in response to global climate change. However, little quantitative information is available about carbon stocks and processes in …

Environmental change and soil organic carbon storage in a dust emission hotspot, Free State, South Africa
… for enhancing the storage of soil organic carbon and associated ecosystem services. To investigate how the shift in land cover or land use affects the occurrence of dust from 2006- 2016, the study firstly identified the spatial and temporal changes of land cover (LC) using the 2000 and …
