A new study warns that climate change will bring significant changes to weather patterns and coastlines, with serious planning implications for Sydney, Australia.
"Sydney's iconic beaches, coastal houses, commercial property and roads will be threatened by rising sea levels by 2050, while the city's temperature is expected to rise by at least 2 degrees, a new scientific study reveals.
The study finds that bushfires are likely to be more intense while rainfall may become more erratic, creating water shortages. But while winter rains decline, intense summer rain in parts of Sydney could increase flash flooding. This, combined with higher temperatures, is expected to put the state's emergency services and health services under stress.
The study has enormous implications for urban planning, building standards and flood-risk mapping as well as agriculture. It finds by 2050 the expected sea level rise is likely to be 40 centimetres, reaching 90 centimetres by 2100. While the figure sounds deceptively small, a one-centimetre sea-level rise can cause erosion effects of up to one metre."
