Rising sea levels - The greatest lie ever told

Anchor · 03-29-2009, 09:09 PM

It doesnt matter if its the sea levels rising, or the landmass sinking, the effect is the same.

Granted all the spin on climate change is not helpful, but I for one am ensuring that I live in places that are at least 150m ASL and my ideal retreat would be >800m ASL (where it is a little cooler).

I know that not everyone gets a choice but I see the sea level being an issue over the next 20 years.

Yes it does here, because I am trying to show that sea levels may not be rising - these islands were brought forward as proof, and I have shown that A) they are on a very active plate line (multiple plates in fact join in this area) and B) the expert says the sea is not rising and he is being silenced - I actually agree with him, as in the 100 years my mothers family have lived on the coast, the sea hasn't risen an inch.

I agree. Totally agree with you - above 150 is a nice little comfort / buffer zone.

as for those poor islanders, well, it truely is a heart renching thing to see what ever the cause of their plight is.

From the article:-

The reason why Dr Mörner, formerly a Stockholm professor, is so certain that these claims about sea level rise are 100 per cent wrong is that they are all based on computer model predictions, whereas his findings are based on "going into the field to observe what is actually happening in the real world".

Thanks for this interesting info Egg. Dr Morner is A TRUE EXPERT in my book because he has questioned the computer model predictions and done his own research.

I dunno about that Egg. Our coasts in New Zealand are being eaten away in places. Its not just a computer model here, you can see it. The coast off Oamaru,(east coast South Island, a guy lost his building to the sea! I sure as hell don't want to be on the coast in the next few years!

Cheers

Coastal erosion isn't the same as sea levels rising though. Cliff erosion happens because the rock is weaker than the might of the sea - any coast line that is not granite or other suitably hard stone will be eroded over time.

Just use google earth to look at the coast of south east england, and then look at the coastal cliffs of Scotland. Cliffs are fine up there, but down south they are made of chalk or sand stone and are getting eaten away.

I still don't want to live near the coasts for the simple reason of a major earthquake causing a major tsunami.

I don't believe that the seas are rising because of global warming. Even if they were, it would be a gradual thing over years. It's the sudden wave I am concerned about.

I hear you on that one. Thats why I am moving to higher / more remote ground in the coming months.

Hello!

Remebered that I read a lenghty "article" about this and actually managed to find from my bookmarks.
Hopefully this comes handy to some one!

Testing The Waters: A report on sea levels

Quote:

The future rise in sea level, according to the IPCC [23] [25], will be caused by two factors. First, the waters of the oceans will expand in volume due to global warming, just as metal expands when heated

This was written in the article. ummmm my science teacher told me that water expands when it is frozen! Your ice cubes get bigger in the tray not smaller. oh well guess this guy went to smarter school.

I think it works both ways. When water freezes it expands because of the transformation into chrystalline structure, and when liquid, thermal expansion takes place. Just a guess tho.

That is because water is pretty special... It has a triple point for one and also as it freezes and the molecules start to slow down they form a crystaline structure which is less dense than water the reason for this is the strong covalent bond (which is almost ionic-like in nature) with H2O and its triangular nature causes a positive and negative nature to the molecule and they line up forming ice lighter than water.

Well at least that was what I learnt in my physics degree if that was 'correct' and not made up too.

Yep, fortunately floating already, so shouldn't increase the sea level, but a real indication of the rising temps down there. And the speed at which they're rising.

Humble Janitor · 03-30-2009, 06:30 AM

How can it be a lie when the other planets are warming too?

It's just as dangerous to call something a lie as it is to call it the truth. I think that we really don't know as much as we think we do.
