Climate Projections for the Tropical Pacific Region - Alex Sen Gupta (UNSW)

Abstract:

The climate and economies of island nations in the Tropical Pacific are strongly reliant on the surrounding oceans. Future anthropogenic climate change is likely to drive major changes in the physical and biogeochemical state of the ocean leading to major disruptions for these developing countries.

In this talk I'll summarise some of the main findings from two recent international studies into the effect of anthropogenic climate change on regional climate and marine ecosystems, and discuss some of the physical processes driving projected changes.

Bio:

I am a senior lecturer at the Climate Change Research Centre. My research revolves around the role of the ocean in the climate system, how the ocean influences regional climate, the influence of ocean change on biological systems and what global climate models tell us about the future of the ocean. Recently I have been using climate models to understand changes to the Tropical Pacific and Southern Oceans in a warming world. In particular, can we trust these models and what can they reliably tell us about the future.
Some of my projects have looked at:

- how tropical ocean circulation is likely to change in the future
- abrupt and erratic migration of marine species as ocean temperatures increase
- causes of warming ‘Hiatus’ periods
- the effect of climate change on Tropical Fisheries
- problems in climate models and how to address them
- Developing a Lagrangian (Individual Based) model of tropical Pacific Tuna
- Characterising and understanding Marine Heat Waves

Mineral resources on the seafloor - A new industry for the SW Pacific?

Abstract:

Increasingly people are talking about the ocean floor as the ‘next minerals frontier’ in terms of its mineral resource potential. As terrestrial mineral deposits become harder to find, less accessible to their market (particularly in the case of bulkier products such as building sand) and technologically more challenging to extract, it is almost certain that we will turn our attention to the relatively unexplored sea floor as a source of new resources/reserves. Indeed, new discoveries, particularly in the SW Pacific, of a range of mineral deposit types, together with improved knowledge and technologies for exploration, are adding a touch of reality to this interest. It has been suggested that 5% of the world’s metals (including Co, Cu and Zn) could come from the seafloor by 2020, generating A$7.5 billion and this could rise to 10% (up to A$15 billion) by 2030. In addition, the resource potential for Mn from nodules is globally estimated at over US$1 billion.

There are clear economic opportunities for a seafloor exploration and mining industry, particularly for some of the smaller nations of the SW Pacific. But, despite the growing interest, we still know more about the surface of Mars than we do about the ocean floor. Seventy percent of Earth is covered in water, so exploration of the ocean floor is difficult, expensive and time consuming: less than 0.05 percent of the ocean floor has been mapped to a level of detail useful for detecting items such as airplane wreckage or the spires of undersea volcanic vents. There are still many unanswered questions and high levels of uncertainty surrounding the likely nature of a marine mining industry, the technology required and the potential environmental and socio-economic impacts.

Joanna has been with CSIRO since 1993 when she joined the Seafloor Ore Systems research group to investigate hydrothermal vents in the Bismarck Sea. After a stint working with the CSIRO Oceans Flagship, she is now back with Mineral Resources and leads the Ore Deposit Geology Group. Joanna continues to have interest in marine geology, in particular the ore deposits associated with seafloor hydrothermal systems, as well as the integration of a range of geological skills to understand ore deposits at the whole-of-system scale.

Planetary Health: A new science for exceptional action - Prof Tony Capon

Abstract:

By most measures, human health is better now than at any time in human history. However, these gains in human health have been unequally distributed and have come at the high price of degradation of natural systems on a scale never before seen in human history. Published in 2015, the Rockefeller Foundation–Lancet Commission on Planetary Health report Safeguarding human health in the Anthropocene epoch concludes that the continuing degradation of natural systems threatens to reverse the health gains seen over the last century. In short, we have mortgaged the health of future generations to realise economic and development gains in the present. Anthropogenic global changes–including climate change, ocean acidification, land degradation, water scarcity, biodiversity loss and toxic pollution of air, water and ecosystems–have direct and indirect health impacts. The consequences for future health are far reaching, ranging from increasing emergence of zoonotic diseases, food insecurity and malnutrition, to conflict and displacement. Those who are least responsible for driving these changes–poor people in developing countries–will be most vulnerable to their consequences. Put simply, planetary health is the health of human civilisation and the state of the natural systems on which it depends. Humanity can chart a safe, healthy and prosperous course ahead by addressing unacceptable inequities in health and wealth within the environmental limits of the Earth however, to do so, will require the generation of new knowledge, the implementation of wise policies, decisive action, and inspirational leadership.

Tony Capon is professor of planetary health in the School of Public Health at the University of Sydney. A former director of the global health institute at United Nations University (UNU-IIGH), Tony is a public health physician with research interests in urbanisation, sustainable development and human health. Previously, Tony held professorial appointments at Australian National University and the University of Canberra. He was the founding convenor of the climate change adaptation research network for human health in Australia and currently leads the Adapt NSW Human Health and Social Impacts Node, jointly funded by the Office of Environment & Heritage and Ministry of Health.
