Synthesising uncertainties of transient sea level rise projections
Global sea levels increased by around 0.2 m over the 20th century and will continue to rise during the 21st century and far beyond. This has profound implications for coastal populations, infrastructure and ecosystems ...
Determining the effective surface area of minerals and the implications for near wellbore geochemical reservoir stimulation
Sufficient CO2 injection capacity is a key criteria for a prospective CO2 storage site and has proven to be a technical impediment for the development of a CO2 storage operation, for example, in case of the ZeroGen project. ...
Reactive barrier formation as CO2 leakage mitigation technology
Global climate change driven by the emission of carbon dioxide (CO2) to the atmosphere is one of the grand challenges of our time. Energy from the use of fossil fuels is the main source of anthropogenic CO2 emissions. While ...
Aspects of Australia’s fugitive and overseas emissions from fossil fuel exports
Australia is a large global energy supplier. It is the world's largest coal exporter and the second largest Liquified Natural Gas (LNG) exporter, leveraging the technological improvements to extract unconventional gas. A ...
Towards an improved methodology for Energy Return on Investment (EROI) for electricity supply
The challenge of decarbonising electricity grids is urgent, but pathways towards decarbonisation are uncertain. Integrated assessment models (IAMs) and energy system optimisation models (ESOMs) are used to project future ...
Climate justice: can we agree to disagree? Operationalising competing equity principles to mitigate global warming
With the Paris Agreement, the international community has agreed to limit global warming to well below 2 °C and to pursue efforts to stay below 1.5 °C (UNFCCC 2015a) to avoid dangerous climate impacts. Staying within these ...
Thermochronological insights into the morphotectonic evolution of Zimbabwe, southern Africa
The Zimbabwe Craton and surrounding mobile belts that make up Zimbabwe form the north-eastern part of the Southern African Plateau, which is of great scientific interest due to its anomalous elevation. The Phanerozoic ...
Uncertainties in runoff projections in southwest Western Australia and central Chilean catchments
Important runoff reductions have been reported in mid-latitude, Mediterranean-like climate catchments of the Southern Hemisphere (SH), in particular in the southwest of Western Australia (SWA) and in central Chile (CC). ...
The composition of altered oceanic crust: Implications for mantle evolution
The geochemical characterisation of oceanic crust, in its dual role as a mantle-derived melt and a subducted material, is an essential component in understanding the evolution of the Earth’s mantle. Interaction of newly ...
Deep seawater circulation through oceanic crust stimulates the subseafloor biosphere
The deep subseafloor hosts the largest prokaryotic biomass on Earth, with cell abundances 3-4 orders of magnitude higher than the overlying ocean. Oxidant concentrations in the subseafloor are consumed sequentially by ...
