Fort Denison, an old penal colony in the middle of Sydney Harbour, has one of the oldest tide gauges around, having been located there for 128 years. During this period, the sea level has risen just 6.5 cm, or about two and a half inches.
Despite these trivial sea level rise over the past century and a bit, moonbat councils on the east coast of Australia are still tying up waterfront properties in miles of green tape, justified by predictions of massive sea level rises by climate alarmists, and property values have plummeted as a result:
In mid-2010, the Eurobodalla council, south of Shoalhaven, introduced a unique interim sea level rise policy that shackled more than a quarter of all properties in the shire to restrictive development controls. Predictably, there was an immediate shire-wide decline in property values.
In three years, individual Eurobodalla properties lost about $40,000 in value. With 22,000 properties in the shire, this represents a capital loss of $880m at a rate of $293m a year. This steady loss of rateable value means householders will face higher rate increases.
If similar policies were implemented along the entire east coast there would be annual property capital losses of billions of dollars.
So it is not surprising that NSW and Queensland governments are reconsidering their coastal management policies.
Queensland Deputy Premier Jeff Seeney recently notified Moreton Bay Regional Council of his intention to direct it to amend its draft planning scheme “to remove any assumption about a theoretical projected sea level rise due to climate change from all and any provisions of the scheme”. Seeney said his intention was to use a statewide coastal mapping scheme “that will remove the ‘one size fits all’ approach that incorporates a mandatory 0.8m addition to historical data”.
At last, a responsible government has recognised that global average sea-level change is no more relevant to coastal management than average global temperatures are to the design of residential heating and cooling systems — local weather and local sea-level change is what matters. (source)
A bit of Aussie climate sanity for once.
