SYDNEY (Reuters) - Australians Lesley and Doug McGrath have for decades battled ocean swells that have eaten away at the backyard of their multi-million dollar Sydney home.
They bought an old beach shack on Collaroy Beach in 1976 and replaced it with a two storey home anchored to the land by 12 meter (35 feet) long piers, a concrete slab, and an underground seawall of giant boulders.
Even with all that protection, the fury of the ocean has at times torn up their backyard, large chunks of prime real estate disappearing under waves. With scientists predicting a 90cm (3 feet) sea level rise in Sydney by 2050 due to climate change, the house itself may yet be in danger.
The McGrath home is one of an estimated 700,000 plus coastal properties in Australia alone that are threatened by rising seas.
Around the world, owners of prized seaside properties face the prospect of not just losing their homes but receiving no compensation as insurance policies may not cover climate change losses in the future.
"If you live in paradise you accept what the ocean gives and takes. We're not worried," Lesley McGrath told Reuters.
Her family photo album tells an amazing story of their battle against the ocean: At times, an expansive beach separates their home from the sea, and at other times, the surf is so close that photos show her son jumping into the water from the backyard.
Sea levels are widely expected to rise about one meter (3.3 feet) this century due to climate change, faster than the 18-59 cms (7-23 inches) outlined in a United Nations Climate Panel report in 2007.

Even those wealthy Australians with their beachfront properties and magnificent views of the ocean are probably bright enough to get out of the way if it gets bad.
Yea, last I heard Port Aransas was being swallowed up by the Gulf of Mexico, but Port Lavaca is doing just fine. (sarc off) Doesn’t anyone understand what “sea level” is?
bwahahaha. Who would have ever thought that every stupid hollywood b-movie would become the global narrative?
What's next, monsters attacking Tokyo?
Yup. It's a play on Chuck Leavell's first initial and last name. A one-hit wonder that spun off from the Allman Brothers.
When a person builds their home so close to the ocean, they should also take into account the various typhoons, hurricanes and other maelstroms that frequently occur along the coastlines.
It is like the potential risks when people live in the wilderness and the threat of forest fires like the ones currently taking their toll in California.
People must always recognize the risks and the potential for complete destruction that may result from natural or man made disasters (from arsonists for exampl), I have always felt that the penalties for arsonists should be extremely more severe than what they currently are.
Guess it's been rising for a long time. A lot of homes in Santa Barbara have been lost to the sea, before and since my stay there.
But OMG, if your numbers are right we're going to be underwater long before the end of the month! I guess we need to break out the kayaks and start stocking them.
Wonder if the clans had a meeting and taxed and regulated. More than likely they just pulled up stakes and moved.
Global warming/climate change has been faltering, and I see this and more stories coming down the pike to bolster the UN in its quest for global taxes and regulations to "save the planet."
Their arrogance is that of a flea crawling up an elephant's hind leg with rape on its mind.
How long has Holland been fighting the sea? One of these years, they may lose.
If these global baloneyists get their way and stifle us with regulations and taxes, what are they going to do about the sun and the ocean and other really major effects on climate change?
Demned idiots.

“Widely expected” my behind.......
These climate nuts actually think people will just stand there and let the ocean rise around them and then drown.
It would be tough to run away from a 3 foot rise over a 40 year period, like one of those nightmares where you can't run fast enough.

Your analogy is just a little off. Ice floating in a glass water will not raise the level of water in the glass when it melts. The water level should remain the same after the ice melts.
What will happen if the ice caps melt will be like putting ice cubes in a funnel above the glass. When they melt it will raise the level of water in the glass.
Manmade global warming is a hoax so the analogy will not manifest itself in the real world anyway.
Excuse me? We've lost a few in Isla Vista (by UCSB), the back of Santa Barbara Cemetery (many years ago), part of Channel Drive in Montecito and part of Shoreline Park on the Mesa, all due to beach cliff erosion (although our benighted city council concluded the park damage was caused by burrowing squirrels). Some beachfront homes were damaged rather badly in the raging storms in the 80's, but I don't recall any great lot "lost to the sea." In fact, except for those condemned in Isla Vista, I can't think of any.
The Great Lakes used to be much lower. They've also been much higher.
This happens with or without GW.
I repeat.
Take a water glass and fill it with ice. Then fill to brim with water. Wait.
Level of water is LESS when ice is melted. Water expands when it freezes! Works with Scotch whiskey, too!
... The increase in volume of ice is about 9%. This increase causes enough force to break most rigid containers. This is the same force, repeated on a daily basis, that creates "pot holes" in the roads in the winter time.
I doubt seriously that the ocean will rise appreciably over the centuries unless there is some cataclysmic event such as a record breaking solar flare or the Van Allen belt that encircles the Earth somehow catches fire or the protective ozone layer of the Earth completely vanishes or the Earth is hit by a meteor of extraordinary size. But all these things are hypothetical. Could they happen? The possibility exists but the possibility is quite remote IMHO. I doubt any effect of global warming will in and of itself cause such a precipitous rise in the sea level.
I would have ended right there. If ALL the ice on the planet melted, the net would be a probable DECREASE in volume, not an increase. The only way the oceans can rise is if they are displaced by volcanic or other action to change the topography.
I don't get any gum't grants, so I am probably wrong...
