riends of Coffin Bay is concerned that Council's Master Plan does not consider the effects of climate warming despite it being an ultra-critical global issue. It is called a "climate emergency" by the United Nations and 14,000 scientists from 158 countries agree.
It is said that over 60% of global biodiversity has vanished in the last 50 years and the serious effects of climate warming are now being seen around the World almost daily. As the average temperature has risen, it has heightened the frequency and intensity of extreme weather events in general. Recent extreme weather events include flooding in Germany and Belgium (165 dead at the time of writing), heatwaves in areas of the Northwestern United States famed for cool foggy weather that killed hundreds, record high temperatures in Moscow and wildfires in the Rocky Mountains and the American West. In Oregon this month, baby hawks were seen leaping from their nests to escape extreme heat. In Canada, an "unprecedented" heatwave caused a massive die-off of mussels, clams and other marine animals along the coast, and farmers reported cherries cooking on the trees.
Our own experiences with extreme weather events here in Australia have been similarly dire. Droughts, flooding and bushfires have become more frequent, and more extreme. On 11th January, 2005, with Fire Danger Indices on the Eyre Peninsula recorded in excess of 300, the Wangary fire burnt approximately 78,000 hectares with significant losses including 9 fatalities, 93 houses, 237 sheds, approximately 47,000 livestock and 6,300 kilometres of fencing.

Sea level rise is another area of significant concern for Coffin Bay residents. The SA Government's Flood Mapping Viewer predicts an approximate 30 cm sea level rise by 2050, and a 1 metre rise by 2100. Further, it shows that by 2050, significant areas of the Coffin Bay foreshore are likely to be inundated in the event of a 1-in-100-year storm surge, including parts of the development at Angasi Shores. These predictions worsen by 2100. You can view this for yourself by clicking on the link below.

The Local Government Association of South Australia acknowledges that climate change poses a serious risk to local communities and ecosystems, and says that "Councils shall ensure assessments are conducted with full consideration of available relevant information as part of all Council strategic and operational planning processes across all services". We cannot see that Council has conducted any such assessment as part of development of the Coffin Bay Draft Master Plan.
Global warming will increase the average temperature of the lower Eyre Peninsula which in turn will cause an increase in the demand for water and energy. Unchecked tourism means that these demands are unlikely to be met. Byron Bay, Margaret River, Bruny Island and other places are all being inundated with tourists and have reached the point of "over-tourism". How - in the face of increasingly severe heat waves, droughts, storms, floods, bushfires and rising sea levels - will our environment, energy infrastructure, water supply and community cope?
Our view is that local communities are best placed to understand and respond to the challenges to their social fabric and environment, and must be genuinely engaged - and heard - in any planning process regarding growth in their region.
