<p>Continued fossil fuel burning is likely to increase CO2 concentrations in the atmosphere to previously unknown levels and emissions will continue to outpace uptake, unless limiting action is taken. This paper presents new approaches to mitigate emissions and drawdown atmospheric CO2 , that is, new combinations of developing and existing technologies in offshore settings. We consider the permanent and safe geological storage of carbon dioxide (CCS) through in situ carbon mineralization and the potential for CO2  uptake and disposal in offshore basalt formations. The CCS concept in general aims to separate CO2 from industrial emissions, and/or directly remove it from the air, and permanently store it underground. Integrating these technologies with renewable (wind) energy in offshore settings may offer a scalable, long-term climate mitigation choice that warrants early consideration. Current studies of co-located opportunities and new offshore demonstration projects are considered. </p><p> </p>

The Impact

In 2019–2020, a particularly bad bushfire season in Australia resulted in cattle being exposed to prolonged periods of smoke haze and reduced air quality. Bushfire smoke contains many harmful pollutants, and impacts on regions far from the fire front, with smoke haze persisting for weeks. Particulate matter (PM) is one of the major components of bushfire smoke known to have a negative impact on human health. However, little has been reported about the potential effects that bushfire smoke has on cattle exposed to smoke haze for extended periods. We explored the current literature to investigate evidence for likely effects on cattle from prolonged exposure to smoke generated from bushfires in Australia. We conducted a search for papers related to the impacts of smoke on cattle. Initial searching returned no relevant articles through either CAB Direct or PubMed databases, whilst Google Scholar provided a small number of results. The search was then expanded to look at two sub-questions: the type of pollution that is found in bushfire smoke, and the reported effects of both humans and cattle being exposed to these types of pollutants. The primary mechanism for damage due to bushfire smoke is due to small airborne particulate matter (PM). Although evidence demonstrates that PM from bushfire smoke has a measurable impact on both human mortality and cardiorespiratory morbidities, there is little evidence regarding the impact of chronic bushfire smoke exposure in cattle. We hypothesize that cattle are not severely affected by chronic exposure to smoke haze, as evidenced by the lack of reports. This may be because cattle do not tend to suffer from the co-morbidities that, in the human population, seem to be made worse by smoke and pollution. Further, small changes to background mortality rates or transient morbidity may also go unreported.
