sea levels
Submitted by duncan61 on Sat, 2015-10-24 11:01
I was just cleaning the BBQ with newspaper and an article on cockburn sound caught my eye.This theory of sea levels rising and were all going to die mentality does anyone buy it.I dont one little bit.I can prove that if the polar caps melt the sea will fall 33 feet and you will be able to wall to garden island and rottnest.in the 50s and 60s it was nuclear threat in the 70s and eighties it was the rainforest and there will be no air left.When does it end

If the ice caps melt why
If the ice caps melt why would the sea level fall?
I scratch my head at some of the claims also but cant work out how your going to prove that the water level would go the opposite way?

Desplacement
The theroy is that when water freezes (becomes ice) that it takes up 1/3 more area/room than the same amount of water. Since the ice caps themselves desplace water if the ice were to melt than there would be rooom/area for more water. This does not take into account all the ice which is above sea level on land i.e. glaciers.
Comparative VolumesSince water has a greater density than ice, water will occupy more space after it changes from a liquid to a solid state. In other words, ice will have a greater volume than an equal weight of water. Based on the comparative densities given in “Serway’s College Physics,” a kilogram of liquid water occupies a volume of 1,000 milliliters while a kilogram of ice occupies a volume of 1,091 milliliters.
My 1/3 maths is a bit out I think.

theory
It is not my own theory but one I read from a proffesser.the Artic is pure ice and although 1/10th is out the sea it has trapped air and if melted it occupies less space than it currently does also allowing for the land mass of Antartica it still works out the sea will have less volume not more.I started this forum on the hope some one can prove the sea will rise.Why are all the people who claim the sea will rise in thier 20s 30s and all the people who say no are in thier 60s and 70s.
just do it.

Its all crapola
Oil was going to run out in the sixties, its a no brainer everyone puts in more desalination plants

but just for clarification
but just for clarification the general "greeny theory" is that if the "Antartic and Greenland" sheets melt (which are not floating but ice supported by land) then sea levels will rise. which ofcourse it will. its generally these two land based ice masses that if melt support the theory of sea levels rising.
whether they melt or not who knows

Frozen water expands. If it
Frozen water expands. If it melts it has less volume? All the underwater ice will have less volume when it melts but......the above ocean ice will run into the sea. Might all equal out.
If it starts rising dig a "cut" into lake Eyre, its below sea level. Would create an inland sea and lower the ocean level??? Put in Desal plants and turn the desert into the food bowl of Australia?
All to much for my small brain

That sounds pretty good
Then we can also sell the food bowl to China like everything else.

Chicken little goes to uni?
Well I just went to woodsman point and the water level had dropped since yesterday, ..........................oh , its low tide now , ok scrap that.
But the point i am making is, no Duncan you not alone , in thinking that theres less people digging ditchs, lifting heavy things etc in society
so we all have alot more time to be projecting what may or may not happen!

no greeny here...
vut i can definately say they are melting, i have witnessed it first hadn in antarctica.
beautiful place that is and would highly recommend a visit to anywhere down there
a hard days fishing still beats work

personally I think we have much bigger concern's then rising sea levels. We're gonna blow each other up way before we are taken out by 'natural causes'. Too many nut cases with nukes out there for my liking! Best off to ignore all that shit and just try have a good time during our short time on the earth

Positive spin
I guess if the sea levels rise, I wont have as far to travel to go fishing, and all the houses between me & the coast will disappear. That's gotta be good for my house value as I will be closer to the coast Haha.....
Cheers & Stay safe

Ellenbrook will be coastal
Ellenbrook will be coastal so I have a shorter drive the water. Win win.
On a side note, did anyone catch the recent finding that the sea level wasn't rising in freo, the stick they use to measure it was sinking because too much ground water was being extracted?
On the subject of melting ice, what did the cave men think when we started coming out of the last ice age? And note the term 'last' as the earth has been heating and cooling for millions of years. Humans have only been around for thousands of years so only go by what we see in recorded history.

Humans are arrogant and self serving. Global warming won't phase us we'll just adapt. And fuck everything in our way, just being truthful.

The Antarctic ice sheet is
The Antarctic ice sheet is about 25 million cubic km. It is not floating, but sitting on top of the Antartic continent. If all that melts sea levels will rise. It would be foolish to believe anything else.
The argument about contained air is wrong. If ice is floating in water, when it melts the water level does not change. If air was trapped in the ice, it would simply float higher, and displace less water, meaning still no change when it melts.

Rising sea level
Bring it on
More fishing spots
Seriously
Global warming is a fact, but whether man has contributed more to it than Mother nature intended is in dispute. She has always gone through ebs and flows of heat and cold with evidence of abundant life in bloody cold places historically evident as oil deposits which mostly come from organic matter long term decomposition. Sea levels have in the past fallen because areas now isolated by seas have been crossed and shown by antropology. The age of these crossing certainly pre-date us using boats so had to be by land (im sure they couldnt swim that far - and the pre-historic sharks make GWS's look like sardines!!!!.
Similar genotypes between people in East Asia and Indians for example, and Aboriginals have more Denisivon genes than most, and they lived in China (what science knows mostly probably at the same time as H.sapiens and neanderthal co-existed). These land bridges are not in dispute and thus sea levels must have been much lower. So if they were lower then and other times, they could rise now and into the future.
Have we added to this - IMO perhaps, but not 100%.
Oh Ps: yes Im scientific but not to do with this issue. Just understand that TO UNDERSTAND you have to read many different viewpoints.

Climate changes
irrelevant of what we do.
Sea Levels have risen about 120m in the last 20,000 years and less than 10m of that has occurred in the last 7,000 years.
There's far more chance of further Fukushima type events occurring and destroying Earth as we know it, before sea levels really start affecting us.
We are very fortunate to have our current playgrounds to explore and fish. Appreciate what you've got, while you've got it.

earths going down eventually,
earths going down eventually, no doubt. only argument is how, the real question is how to get off this planet, we need better space propulsion to go into space. i wonder if they have fish up on mars with all this liquid water they found.
Fishing and catching are two different things. But i want to learn how to catch.
