"Meeza real scared now!"

SEA levels on Australia's eastern seaboard are rising at less than a third of the rate that the NSW government is predicting as it overhauls the state's planning laws and bans thousands of landowners from developing coastal sites.
The Rees government this week warned that coastal waters would rise 40cm on 1990 levels by 2050, with potentially disastrous effects.
Even yesterday Kevin Rudd warned in a speech to the Lowy Institute that 700,000 homes and businesses, valued at up to $150 billion, were at risk from the surging tide.
However, if current sea-level rises continue, it would not be until about 2200 - another 191 years - before the east coast experienced the kind of increases that have been flagged.
According to the most recent report by the Bureau of Meteorology's National Tidal Centre, issued in June, there has been an average yearly increase of 1.9mm in the combined net rate of relative sea level at Port Kembla, south of Sydney, since the station was installed in 1991.
This is consistent with historical analysis showing that, throughout the 20th century, there was a modest rise in global sea levels of about 20cm, or 1.7mm per year on average.
By comparison, the NSW government's projections - based on global modelling by the Intergovernmental Panel on Climate Change as well as CSIRO regional analysis - equate to a future rise of about 6.6mm a year. Such a projection has caused widespread concern for landowners and developers, derision from "climate sceptics" within the scientific community and even some head-scratching from Wollongong locals such as Kevin Court, 80.

We’re all gonna drown!
Well, at least get damp.
I am willing to wager in many parts of North America the rebound effect from the last glaciation period negates the effects of any sea level rise.
Ping.
1.7 mm is barely enough to threaten a sand castle, much less Manhattan.
bttt
He11, they rise more than that every 6 hours.
Hey... nice cast for that movie? Is that real?
And all this water is going to come from where?
1.7mm? How can they even MEASURE such a meteoric rise?
Isostatic rebound is another term you will never see discussed by Big Media. Canada's land surface is still fairly depressed from the last glaciation. But it is why Canada has so many huge lakes and trillions of mosquitoes.
