After emerging from the resources wilderness thanks to its world-class geology and industry-friendly government policies, South Australia is now a leader in Australian mining and hydrocarbon developments over the last decade. In little more than a decade the State has gone from four operating mines to more than 20 and is rated Australia’s second most popular exploration destination. With a comprehensive review of the Mining Act under way, the State’s attractiveness as a place for resources and energy investment is expected to be strengthened. South Australia is now a leader in the exploration for next generation energy sources with companies such as Santos and BP leading the charge, while initiatives such as the Government’s Copper Strategy – designed to treble annual copper production to 1 mtpa – is set to establish the State as one of the world’s premier producers of the red metal. In the energy space, uranium and nuclear energy is another area of keen interest, with the South Australian Government initiating a Royal Commission into Participation in the Nuclear Fuel Cycle in 2016. The State has become synonymous with innovation, cutting-edge development and a remarkable rate of discovery. From uranium prospects, to geothermal energy and the buoyant hydrocarbons sector, South Australia is now a leader in the exploration for next generation energy sources. With full support from the Department of State Development, the South Australian Resources and Energy Investment Conference will continue to showcase this burgeoning sector in 2017. From copper plays in the Gawler Craton, to iron ore and graphite developments on the Eyre Peninsula and the emergence of the State as a new hydrocarbon frontier, South Australia’s resources potential is at last being fully recognised. The conference will feature the success stories and emerging players in the State from both minerals and oil and gas and will also tackle thorny industry issues such as infrastructure, corporate social responsibility and the future of the Woomera Prohibited Area.

Marine and terrestrial biogeochemical models are key components of the Earth System Models (ESMs) used toproject future environmental changes. However, their slow adjustment time also hinders effective use of ESMsbecause of the enormous computational resources required to integrate them to a pre-industrial equilibrium. Here,a solution to this "spin-up" problem based on "sequence acceleration", is shown to accelerate equilibration of state-of-the-art marine biogeochemical models by over an order of magnitude. The technique can be applied in a "blackbox" fashion to existing models. Even under the challenging spin-up protocols used for Intergovernmental Panelon Climate Change (IPCC) simulations, this algorithm is 5 times faster. Preliminary results suggest that terrestrialmodels can be similarly accelerated, enabling a quantification of major parametric uncertainties in ESMs, improvedestimates of metrics such as climate sensitivity, and higher model resolution than currently feasible.

The thermal continuum emission observed from accreting black holes across X-ray bands has the potential to be leveraged as a powerful probe of the mass and spin of the central black hole. The vast majority of existing ‘continuum fitting’ models neglect emission sourced at and within the innermost stable circular orbit (ISCO) of the black hole. Numerical simulations, however, find non-zero emission sourced from these regions. In this work, we extend existing techniques by including the emission sourced from within the plunging region, utilizing new analytical models that reproduce the properties of numerical accretion simulations. We show that in general the neglected intra-ISCO emission produces a hot-and-small quasi-blackbody component, but can also produce a weak power-law tail for more extreme parameter regions. A similar hot-and-small blackbody component has been added in by hand in an ad hoc manner to previous analyses of X-ray binary spectra. We show that the X-ray spectrum of MAXI J1820+070 in a soft-state outburst is extremely well described by a full Kerr black hole disc, while conventional models that neglect intra-ISCO emission are unable to reproduce the data. We believe this represents the first robust detection of intra-ISCO emission in the literature, and allows additional constraints to be placed on the MAXI J1820 + 070 black hole spin which must be low a• < 0.5 to allow a detectable intra-ISCO region. Emission from within the ISCO is the dominant emission component in the MAXI J1820 + 070 spectrum between 6 and 10 keV, highlighting the necessity of including this region. Our continuum fitting model is made publicly available.

Warming the Earth's Atmosphere: Causes, Effects, and Solutions The phenomenon of atmospheric warming, commonly referred to as global warming or climate change, has emerged as one of the most pressing environmental challenges of our time. It is primarily driven by human activities that increase the concentration of greenhouse gases (GHGs) in the Earth's atmosphere, leading to significant and potentially irreversible changes in climate patterns. This essay explores the causes, effects, and potential solutions to this critical issue. Causes of Atmospheric Warming The primary cause of atmospheric warming is the enhanced greenhouse effect, which occurs when certain gases in the Earth's atmosphere trap heat from the sun. The most significant greenhouse gases include carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), and fluorinated gases. Human activities, particularly since the Industrial Revolution, have dramatically increased the levels of these gases. Key contributors include: Burning of Fossil Fuels: The combustion of coal, oil, and natural gas for energy and transportation is the largest source of CO₂ emissions. Deforestation: Trees absorb CO₂, and large-scale deforestation reduces the planet's capacity to absorb this greenhouse gas, while the burning and decomposition of trees release additional CO₂. Agriculture: Agricultural practices, such as livestock farming, produce significant amounts of methane and nitrous oxide. Industrial Processes: Various industrial activities release GHGs, including the production of cement, steel, and chemicals. Effects of Atmospheric Warming The impacts of atmospheric warming are profound and widespread, affecting natural ecosystems and human societies globally. Some of the most significant effects include: Rising Temperatures: Global average temperatures have increased, leading to more frequent and intense heatwaves. This can result in health problems, reduced agricultural yields, and increased energy demand. Melting Polar Ice and Glaciers: Higher temperatures cause the melting of ice in polar regions and glaciers, contributing to sea level rise. This threatens coastal communities with increased flooding and erosion. Ocean Acidification: The absorption of excess CO₂ by the oceans leads to acidification, which adversely affects marine life, particularly organisms with calcium carbonate shells or skeletons. Extreme Weather Events: There is an increase in the frequency and severity of extreme weather events such as hurricanes, droughts, and heavy rainfall. These events can cause significant damage to infrastructure, disrupt food and water supplies, and displace populations. Ecosystem Disruption: Changes in temperature and precipitation patterns can alter habitats and affect biodiversity, leading to shifts in species distributions and the potential extinction of vulnerable species. Solutions to Mitigate Atmospheric Warming Addressing atmospheric warming requires a multi-faceted approach that combines mitigat

Using deep archival observations from the Chandra X-ray Observatory, we present an analysis of linear X-ray-emitting features located within the southern portion of the Galactic center chimney, and oriented orthogonal to the Galactic plane, centered at coordinates l = 0.08◦ , b = −1.42◦ . The surface brightness and hardness ratio patterns are suggestive of a cylindrical morphology which may have been produced by a plasma outflow channel extending from the Galactic center. Our fits of the feature’s spectra favor a complex two-component model consisting of thermal and recombining plasma components, possibly a sign of shock compression or heating of the interstellar medium by outflowing material. Assuming a recombining plasma scenario, we further estimate the cooling timescale of this plasma to be on the order of a few hundred to thousands of years, leading us to speculate that a sequence of accretion events onto the Galactic Black Hole may be a plausible quasi-continuous energy source to sustain the observed morphology
