    A Science Transfer project led by the Tijuana River and Kachemak Bay Reserves aimed to address these challenges by helping coastal communities on the Kenai Peninsula plan for a changing climate. This document synthesizes the best available science around climate change impacts for the Kenai Peninsula.

    Kauffmann-Hayoz, R. Ecology and Society 11 1 Cambridge University Press. Burton, E. Pate, R. Doyle, D. Fourth, many of the variables of importance to adaptation decisions — such as the frequency of extreme events, the beginning of the rainy season, or the timing of sea level rise — are not well modeled as yet.

    A result of collaboration between Kachemak Bay Reserve staff and researchers, this summary of regional climate science is intended to increase awareness and understanding of climate change science and vulnerabilities among decision makers and to help communities adapt and increase resilience to environmental change.

    Understanding risk and informing decisions

    Personalised recommendations. In order to climate proof infrastructure, the design, building, financing and maintenance of infrastructure must use the best available climate science and adaptation information available from premier agencies such as CSIRO and [the Bureau of Meteorology]. For example, Hobsons Bay City Council submitted:. To effectively plan for and manage extreme weather events, climate projections are needed that are based on the best available science and are relevant to the local area.

    Tyndall Centre research: Perceptions of Climate Change

    This information should be widely disseminated and readily accessible to inform emergency management planning. Wesfarmers explained that it uses CSIRO data to inform climate resilience planning and to improve its 'understanding of the material climate change issues that face our divisions', including physical, regulatory, reputational and competitive risks.

    Mr Peterson argued that continually collecting data and maintaining datasets and making them available to all decision-makers in the economy would help build 'resilience into our economic system'. This is followed by a discussion of the evidence from stakeholders that called for research to be used to develop specific products to assist with planning or for existing guidelines to be updated more frequently.

    This discussion is based on the evidence received during this inquiry. Relevantly, however, the Australian Research Council ARC recently provided funding for a new centre for excellence relating to climate change. For example, Mr Andrew Petersen, Chief Executive Officer, Sustainable Business Australia, commented that, over the last decade, this work has been 'instrumental to a number of businesses' in various sectors, including finance, insurance, infrastructure and construction. It submitted:. While the Climate Council and a few other not for profit organisations undertake pieces of research and prepare publications about the implications of climate change on the matters of concern to this inquiry, there is currently only one organisation, the This service is vitally important to facilitating the uptake of leading thinking by time poor practitioners who are not climate change specialists, but have content expertise e.

    Informing Adaptation

    The cut in funding means that NCCARF will be unable to continue its adaptation research activities including research to further develop the CoastAdapt web tool, which was launched in September to assist coastal councils respond to rising sea levels and other climate impacts. The CoastAdapt web tool quickly became established as a vital source of information and guidance for coastal councils attempting to minimise the impacts of a changing climate on their local communities and environment.

    The decision to cut funding for climate adaptation research was a major disappointment to coastal councils and other agencies attempting to deal with the imminent threat of a changing climate. The LGAQ called on the Government to provide funding to maintain the tool and to expand it to include modules on bushfire, heatwave and flooding. The ARR is prepared by Geoscience Australia and is used by designers and engineers 'for the estimation of design flood characteristics in Australia'.

    For example, a joint submission from a group of engineers and scientists stated:. The edition of ARR did not address potential impacts of climate change at all, so approaches to incorporating climate change prior to the release of the edition of ARR varied considerably between studies, where climate change was considered at all.

    Other examples of tools developed to assist local governments to gain a more detailed understanding of the interactions between flooding and different management measures were provided, including a tool developed by CSIRO to assist local governments located along the Port Phillip coastline. The FMA submitted:. Having access to flood risk information underpins effective flood management and our ability to reduce the flood vulnerability of communities.

    Educating and engaging the broader community on their vulnerability to the impact of flooding and other natural hazards is also essential to building resilience. FMA supports transparency and education around flood risk. For example, the committee was advised that the publication of risk mapping at a local level would help inform decision-making. By ensuring reliable information was freely available, it was suggested that governments could then require investors to take responsibility for any subsequent decisions to build in at-risk areas, enabling future governments to resist future pressure for resources to protect such properties.

    Dr Wise suggested that this work, which is focused on natural hazards, 'could be much more broadly applied to other forms of the more insidious chronic changes caused by climate change'. The national first pass assessment of sea level rise is at a high resolution with limited usefulness for land use planning. Effective mapping that shows likely sea level rises over a range of time periods is needed at a scale that can inform land use decisions. It is most effective to undertake this mapping at a federal or state level due to the scale of the problem and to ensure a consistent approach between regional agencies and include local councils.

    Mapping should be refreshed at regular intervals e. Mapping should clearly communicate the probability of the risk occurring in a way that is clear to the community.

    For example: 'based on the best available science at the time there is a 10 per cent chance that sea level rise will be less than this and a 90 per cent chance it will be greater than this. The FMA argued that a national approach would be useful to overcome resistance in some locations about how the public release of such information could affect property values.

    We acknowledge that many of our Local Government members face political and public pressure due to perceptions—warranted or otherwise—about the impact of releasing flood risk information about property values, development opportunities and insurance premiums. A national approach to how climate change flood risk information should be prepared and publicly disseminated, and how such information should be applied in the planning of existing and new areas, would go a long way to diffusing parochial reluctance in dealing with the issue.

    Every man and his dog is basically picking up that dataset and trying to make sense of it to understand cyclone risk. If we could put much more scientific effort into establishing a much better source of truth there, we'll start being able to have aligned views of risk and what to do about it. Mr Leplastrier explained that a key feature of the TCRM is that it has been set up to enable researchers to 'contribute to the model and improve on it'.

    It's a bit like a local government flood study, which is a very good set of scientific information.

    If we could do that with these other important hazards and then have that available for people like insurers or engineers to pick up, that would be very, very good. Mr Karl Sullivan from the Insurance Council of Australia explained that the insurance sector has struggled to access certain datasets at a reasonable price. Mr Sullivan stated:.
