There is so much talk about disaster coming and indeed already here
that I heard a Pacific Islander delegate talking up how much money
should be given to the Islands because of rising sea levels I stopped
to think about it.
Just how bad is it ? The Coastal Institute at Auckland University
said 65% of Pacific Islands were larger than in 1945, 30% were the same size.

I thought it should be easy to check this as tide heights have been
monitored around Australia since 1788.
So I went to the B o M of Australia and looked up Tuvalu and Ft Denison.
Tuvulu 1993 30.1 Metres
2013 30.141 M
2021 29.69 M
Ft Denison Sydney Harbour
1914 1.111
2021 0.988

That shows a fall in the mean heights but on such a small sample it
is not conclusive but these are yearly averages.
As I scanned down the tables these were very similar figures.
Ft Denison, no change in over 100 years.
So is the sea rising differently in the Pacific Islands ?
If so there must be some monumental currents running.
Or could the Islands be sinking ?
What are other countries supposed to do about that ?
Another conclusion is WE ARE BEING CONNED !

Of course we are conned, by climate activists who are really just religious nutters, earth-worshippers, screeching that the end of the world is nigh. They are rejecting the modern world.

If/when climate change turns out to be no longer an issue, the egos of those identifying with the cause would/will be undermined. That is why they hang on so grimly to the idea. And, of course, there is the biggest redistribution of wealth the world has ever seen

Come on you guys, don’t you know that it isn’t PC to talk logic.

Unfortunately, for the follow-the-science brigade, some science is too inconvenient to follow.

Islands, just like everything else, wears over time. Anyone expecting them to get higher whilst the erosion does its work need their head read !
If anything, islands gradually subside, especially those on unstable ground.

Having seen details of coral islands growing proven since satellite photography could display it so easily, I recently took a trip courtesy of Google Earth, over a few of the atolls I had acquaintance with.

In the mid 70s I built a number of small jetties for plantations on both high, [volcanic], & low, [coral] islands in the Pacific islands. These were to handle the small, [up to about 140Ft] copra boats.

It was interesting. I found no change on the high islands, but on a number of atolls it was quite pronounced. One on the southern windward end of the island, I found the island had moved about 3 meters away from the jetty, & fill had been used to keep it accessible by vehicles. It did appear that new land, not yet incorporated into the planted area had developed at the down wind end.

Three others were being engulfed by the island. One had the island grow out past one end of the brest type jetty, making it a bit more difficult to access, but two others were totally engulfed. One was a full 6 meters inland & the other a couple of meters. One of these the plantation had almost entirely disappeared, enveloped by the bush so no longer managed, but the other was obviously maintained with the rows of palms free of undergrowth or trees.

This highlighted just how much new coral debris is incorporated in to these islands extending & growing them.

Interesting Hasbeen. The ABC dug out some commentators that claimed
the Islands grew because of natural reasons.
However they still have not admitted the global warming theory is
wrong in this case.
Is it because one piece of evidence is wrong then it throws doubt on all the rest ?
No matter how they squirm they cannot deny evidence etched into rocks.

On the edges of Earth Plates we would get variant heights of land with tecktonic movements.

Flop26 is crap and lies. Leading liar, Scott Morrison has promised another $2 billion to Pacific and SE Asian to increase their industrial emissions, and take industry, wealth and jobs away from Australians. Three trillion dollars debt by June next year.

Josephus, I read something about the plate system. It said that Australia was tipping.
I cannot remember which way. It was on a North/south axis The east
coast rising, west coast sinking. Can't remember which way.
It was however on a very long timescale.

Dear Bazz,

Bless your cherry picking little soul.

Here is the NOAA graph for Fort Denison. Only the ideologically tainted would say there isn't a trend line.

http://tidesandcurrents.noaa.gov/sltrends/sltrends_global_station.shtml?stnid=680-140

Flop26 is less about the environment than it is about increasing foreign aid.

It goes without saying & only an utter imbecile would disagree, the pollution humans create is going to choke humankind if humans don't pull their fingers out & stop breeding like rabbits !
Climate will change no matter what humans do or say or think ! Climate is on a timer & that's all there is to it.
Pollution is what we CAN do something about !

Individual,
Agree entirely as long as it doesn’t go to extremes, like California where people hunting with traditional muzzle loading single shot flintlock guns must use other than lead shot.
And new petrol mowers are banned.

The graph 0.65mmx110yrs = 84.5mm.
That is less than most of the differences year to year in the tables.

What about the by now 20 Billion tonnes of shipping displacement ?

Another quip heard about Flop26:

It is 'Rich people congratulating each other in rich people's jargon: "investment", "systemic change", and "inspiring others to to go forward"'.

Dear Bazz,

You really are trying to fudge things aren't you. You can't take it over the entire period and not have some inkling that it might be accelerating.

"Sea Level rise in coastal Australia

In Australia, the trend in sea level has been calculated from long term averaged tide gauge records and satellite altimetry:

1900 to 2011 sea level trend = 1.2 mm/year

1966 to 2011 sea level trend = 1.7 mm/year

1993 to 2011 sea level trend = 4.6 mm/year

The two longest tide gauge records at Fort Denison in Sydney Harbour and at Fremantle in Western Australia indicate a sea level trend of 0.73 mm/yr at Fort Denison and a trend of 1.78 mm/yr at Fremantle."

http://www.ausmarinescience.com/marine-science-basics/sea-level-rise-1/

sea level trend of 0.73 mm/yr at Fort Denison and a trend of 1.78 mm/yr at Fremantle."
SteeleRedux,
That coincides with the increase in shipping tonnage.

Dear Bazz and individual,

Firstly the 0.73 mm/yr at Fort Denison was for the whole of the record and doesn't show the current acceleration of rising sea levels.

Secondly Bazz where did you get the 1914 figure?

I went here: http://www.psmsl.org/data/obtaining/stations/196.php and it shows from 1915 onward.

I then opened up the annual mean sea level figures link which was here: http://www.psmsl.org/data/obtaining/rlr.annual.data/196.rlrdata

I then ran them through a trend line graph with an online calculator which can be found here: http://www.graphpad.com/quickcalcs/linear2/

I was a bit lazy and pegged the year 2000 at 7006 just to allow the calculations to go smoothly.

I got trend figures of:

1960-2020 1.283mm per year

1980-2020 1.911mm per year

1990-2020 2.578mm per year

2000-2020 2.956mm per year

You are welcome to do them yourself.

Of course the smaller data sets start to have huge margins of errors but the 1980-2020 figure of 1.911mm is down to ± 0.3299. The whole thing seems to be so obviously accelerating madly and can hardly be ascribed to increase tonnage now can it.

Wow!! 0.111 inch in 20 years that means that the toes of my shoes will get wet in about 180 years if I left them at a spot where the water is now at high tide; some.acceleration.

Dear Is Mise,

3mm a year is well over an inch a decade and accelerating. Where are you pulling your figures from?

Steele,
From a misplaced decimal point. (*i*)

Global warming is a problem for all of us and it will affect those who believe and those who do not, so be careful and look after yourselves, if everyone looks after themselves we have a chance to survive)))

With recent falls of snow in the northern hemisphere, electric cars fail to heat those stuck in ice and snow.

If this is what our scientists come up with then Science in Australia should instantly be de-funded along with ABC/SBS.

Interesting, the sea rises faster in one part of the world than another.
Sea levels in the Torres Strait are rising twice as fast as the global average.
Surfers should be able to ride the current all the way to London.

Bazz,
Australian scientists who get results to order appear to forget that if you build infrastructure on mud banks they'll gradually subside.

Dear Bazz,

You claimed on another thread that you had been ignored after posting the Fort Denison figures yet I spent some time dissecting them and you turned around and ignored me.

So you have lied.

Please stop.

And what is your response to the figures I put up?

On current records of 0.73mm at Fort Denison in theory means in the last 100 years using the figures would mean it has risen 0.73 Meters which is not the case that the tide is over 2 feet 5 inches higher than in 1921.

The charts show an actual rise from 1925 in 2020 of 200 mm or 8 inches but in the year 2000 it was only 50mm higher than 1925 at Fort Denison,

SteeleRedux,
What's your view on building settlements on sandbanks ?

individual,

Charles Neil who lives in Dubai writes:

"Sand covers the surface of Dubai. For single story/low
rise buildings they can lay a concrete slab that sits on
the sand that provides a very stable platform."

"For tall buildings they are built on piles which can be
drilled in to bed rock which lies at varying depths below
the surface. These piles are close together and form a
type of mattress for the base of the building to sit on."

Foxy,
A desert is vastly different to a mudbank surrounded by water upon which there is a village not being held up by pylons driven into bedrock ! Also, Dubai is a functioning patriotic society creating its own revenue.

Dear Josephus,

Sigh.

Leaving aside you ignoring the accelerating Fort Denison sealevel rise I clearly illustrated perhaps you need to stop being so flippant with your numbers.

0.73mm times a hundred years is not .73 of a metre but rather 73mm or one tenth of that.

individual,

You did ask for a view of building settlements on
sandbanks.

Just note what Hasbeen said;
Jetties he built around the Islands donkey's ago are now not long enough.
Coincides with Auckland Uni's findings.

Dear Bazz,

Lol.

No I'm not going away young fella. As I clearly showed there is an acceleration of sea level increases at Fort Denison.

To have your poster child so utterly deconstructed must smart more than a little, and I get that.

However one day you are just going to have to face up to it because I will drag it out each and every time you flag it as an example.

My advice would be to get over it and find another to shore up your pack of cards because they are certainly teetering.

You did ask for a view of building settlements on
sandbanks.
Foxy,
I did indeed & you can't or more like don't want to see my point which is people who settle on mud & sandbanks are now chasing class action against the rest of us for compensation due to sea level rise. Would you accept their application for insurance if you were an insurance company ?

individual,

Structural engineers take soil tests and design pile
foundations sitting on deep underground rock and
build on top of those piles. If piles are not driven
deep enough building will sink into the ground. As
was the case on record at the Sydney Olympic site.
What happened was the fault of the engineers. Inadequate
tests were conducted on the soil conditions under the
buildings that started to sink.

As for insurance companies? You can contact them and they
will answer your questions.

Foxy,
Are the Olympic crowd asking for money from the Australian Taxpayer for that ?
