Anyone else concerned that all the future great flat water spots will have buildings one them?

yesterday I watched in disbelief and horror as the sea levels rose...

but roughly six hours later, they went back down..

it was all good,

so I went back to eating mushies

Global sea level rise temporarily dampened by 2010-11 Australia floods

Three atmospheric patterns came together above the Indian and Pacific Oceans in 2010 and 2011. When they did, they drove so much precipitation over Australia that the world's ocean levels dropped measurably.

Mean sea level rise in Australia since balinda occupation is 1.6 mm per year. It's currently 3.2 mm per year.
Those clever Dutch sea stoppers are planning for 1.3 m rise in the North Sea by 2100.

I can't help thinking that's optimistic given that there is supposed to be about 70 m of water locked up in ice.

Maybe there is just too many ships, boats and wind surfers with large displacement hulls in the oceans causing the sea level to rise ????????????????

So when the sea rises to much we are the toilet system of the ocean. Ekkk

Gina could capitalize on this one down the track.

Hmm, that's still too slow. I don't really want to wait that long to have a waterfront property.

Archimedes Principle:- A body floating in equilibrium displaces it's own weight in water.

Therefore melting of the Arctic ice Cap will have zero effect on sea levels.

It is only ice sitting on land masses that can possibly have an effect on sea levels if it melts. I doubt that eventuality will happen within the lifetime of anybody on earth today.

Further, evidence suggests that the earth is heading into another "Ice Age" which is also doubtful of eventuating within the lifetime of anybody on earth today, so what is the panic all about???

So stop panicking and go do what you normally do!!!

I think you're confusing weight with volume.

Actually, I think you don't know what Archimedes' Principle is.

Except that a lot of the ice cap is on land, so if it melted it would flow into the ocean and sea levels would rise.

He did say "Arctic" nor "Antarctic". The snow/ice in Antarctica is at its thickest/deepest in known history, whilst the Arctic ice cap is the bit that seems to be decreasing - and it's a floating "ice cap". It appears that most in here are a tad confused.

Just try a little experiment for me.

Fill a plastic bottle with water right to the top, cap it tightly, freeze it and observe what happens.

Another one:-

Fill a glass sitting on a saucer right to the brim with water then gently float an ice cube in the water. Then very gently lift the glass onto a dry saucer. Allow the ice cube to melt and observe how much water overflows into the saucer.

Maybe you never had the privilege of seeing Dr Julius Sumner-Miller on TV when you were a kid.

He used to live around the corner from me when I was a kid. I me him once, and he told me that I spelt my name wrong.

Sheesh - to clarify: There are still 70+ metres of water locked up in ice in Antarctica, Greenland, and sundry cold places. The geological record shows the mean sea level at its highest was more than 70m higher than it is currently. This takes into account variations in land levels due to tectonic movement and the overburden mass of ice.

Local rag "Mandurah mail" from Thurs 22Aug says says a leaked draft of a UN climate change report reckons an 80cm rise this century.
So 80 cm is around about our tide range here. On the positive side is those reefs that are dry sucking now at low tide are gonna have 80cm more water on them making those sections kiteable on low tide.
