Over the medium to long term, climate change poses real and serious threats to our coast.
During this century, it is likely the Victorian coastline will be impacted by sea level rise and increased frequency and severity of storm events leading to inundation and erosion. It is also predicted that higher temperatures will increase bushfire risk along the coast, and increased sea temperatures, changing sea currents and further acidification of the ocean will affect the marine environment.
The Intergovernmental Panel on Climate Change (IPCC) is the authoritative international scientific advisory body on human-induced climate change science. In the Fourth Assessment Report, (November 2007) the IPCC projected sea level rise of between 0.18–0.59 metres by 2090–2099 using a hierarchy of models plus additional ice sheet melt of 0.1–0.2 metres. However, the upper values of sea level rise (e.g. 0.59 metres) projected by the models were not considered to be upper bounds of possible sea level rise by 2099 (refer figure 4).
