Is it true Australia will sink in the next 100 years or so?

Question

Thats what i heard, cos if its true i need to make plans...

Apparently geographically its true.

Answer 1

Australia will not sink so don't worry about it.

Answer 2

If sea level rises by 20 metres, then much of inland Australia will be a sea, joined to the Southern Ocean via spencer's Gulf (South Australia).  Another 10 metres would be enough to split the continent into two island chains.  However, this is a LOT of sea level rise, and even in the worst case scenario is not likely to happen too soon.  This is looking too far into the future.  A greater worry would be the advancement of a new ice age.

Answer 3

what is Australia going to sink into

the only place it can sink into would be the mantle and that will take more than 100 yrs

however if the sea level rises that's different but that will still take more than 100 yrs

true Aus is moving north but so  is Tasmania its following the mainland north so there is no "stretching" of the mountains

the only way the mountains get smaller is by erosion (which takes eons)

as for the coast of S. Aust most of it is over 20 -30 metres and the Great Australian Bight has cliffs over 100-150 metres high

anyway I live here and with the sea level rising at 2-3 mm over the last 20 yrs I have a long time to wait

Answer 4

Don't worry about it.  Making family & estate plans for 100 years from now is pretty absurd.  I heard that it was moving.  Was it North or further South?  I think the former, but I forget.  

I also heard that Venice, Italy is sinking.  They're actually building flotation devices...  It will be a floating city.

Answer 5

one day all this world will vanished and again re birth will started on this earth. so every meterial or every planets are having its own end so one day every thing will destroy...

Answer 6

As global warming progresses, sea level is expected to rise primarily due to the melting of continental ice sheets in Greenland and Antarctica. However, the ultimate amount of flooding is highly uncertain. A full deglaciation of both poles would raise sea level as much as ~65 meters

Australia is the lowest continent in the world with an average elevation of only 330 metres. The highest points on the other continents are all more than twice the height of Mount Kosciuszko (2228 metres).

If the sea level rises by 65 meters, all the coasts of Australia and South Australia will be flooded.

Answer 7

lol what? seriusly these science ppl get so much $$$ to put anything out there lol .....

what if i said in 100 yrs we gonna start seeing trees growing in the clouds/sky ? lol will u believe me? come on now

Answer 8

Australia is moving north at about 3-6cm per annum, as this happens the southern mountain ranges are shrinking,  as they stretch out.  It makes sense.

I would suggest that there is some loss of altitude at aus's southern aspects, but I can't confirm this.  Rising sea levels will of course effect us.  And this year for the first time recorded, there is no Ice at the Magnetic north Pole!  The climate is shifting, and we are still not making inroads into Carbon-Dioxide and Hydro-Carbons released as gases into the atmosphere.  Australia according to the Garneut Report is going to be more affected than most places.  I am riding my bike alot now days.  I like it.

Answer 9

Much of Australia would be submerged, according to the topographical maps, if the worst case scenario about global warming was to eventuate. The West would become divided from the East, and the Adelaide hills would become islands.

Let's hope commonsense prevails, and China, and India begin to adopt a more reasonable position regarding fossil fuels, energy policy, and global warming.

America, Europe, and Australia would be well advised to provide them with cheap, effective energy solutions, such as high efficiency solar cells, and safe nuclear reactors, and electrically powered cars.

Answer 10

Geologically specking the answer is "NO!". Australia is the oldest continent and will be around for a few more years yet despite what a politically motivated scientist says (Garnaut 2008)
