Many Australians are fearful of catastrophic human-caused climate change because this is what the state-sponsored propaganda on the Australian Broadcasting Corporation (the ABC) tells us.
In Australia, we mostly live near the sea. All along our coastline there is evidence of sea level fall, yes fall.*
Where is the evidence for rising sea levels?
Will you see how much sea levels have risen when you watch the fireworks over the Opera House in Sydney Harbour this New Year’s Eve — or will you see evidence of sea level fall?
It is that time of year when family and friends visit me at the beach. My niece told me just before Christmas that she had read so many of the comments at the YouTube thread following my first short film ‘Beige Reef’. She was surprised at how many comments there were — an awful lot she commented.
When I asked her what she thought of the film, she told me that she had not actually watched the film.
At that morning tea, under a shelter at Coolum Beach, none of my nieces or nephews or older brother could admit to having watched the film.
It is all of 12 minutes long.
This first film involved me wading into, and diving below, waters that my sister-in-law some weeks earlier had indicated put me at risk of a shark attack. But still she has not actually watched the film.
I know that there is fear within the varies communities within which I exist, of at least three things: sharks, catastrophic human-caused global warming — and that I could lead some of them down the path of global warming scepticism and from this they could end-up pariahs.
I diverge.
The best evidence is that global sea level has fallen by at least 2 metres since the the Holocene high stand about 4,000 BC; that is about 6,0000 years ago, a time known as the Minoan warm period.
The evidence in rocks and cliff faces all along the Australian east coast is that sea level was about 1m higher in the Roman warm period (year 0), and about 0.5m higher in the Medieval warm period (1,000 AD).
Conversely, it is believed the sea level was lower in the cold periods of 500 AD (Dark Ages) and the Little Ice Age (1,650 AD), maybe both 0.2 — 0.5 metres below today’s level. This last low sea level is particularly important, because it from this base sea levels are perhaps still rising back to average Holocene levels. But are they really?
When I go kayaking, and walk along the sea shore, and send my drone Skido up into the sky and look down and take pictures of things like marine potholes that feature at the top of this blog post: I see evidence for a sea shore that is receding.
The sea begins at the land’s edge. Where the sea begins is the ‘sea level’.
When I stand beside the circular pothole that you can see in the centre of the picture accompanying this blog post (… scroll to the very top).
I’m standing on a wave-cut platform of sandstone bedrock with rectangular fractures, and red iron oxide colouring.
Potholes are formed by the relentless grinding of harder rocks — perhaps granite— caught in a depression in this softer sandstone. Pounding surf causes the harder rocks to swirl — round and round — grinding down.
The grinding that created these potholes could only have happened when sea levels were higher, when this platform was between the high and low tide marks.
I took the picture on a highest tide this last year, in 2019. A year that is nearly over.
Sea levels must have been higher in the past. Because even on the highest tides this last year, the waves never reached this far?
The ABC may be concerned about rising sea levels, but where is your evidence for it? Are you brave enough, do you care enough, can you find the time enough, to think through some of these issues this next year: in 2020?
We are all entitled to our own opinions, but not our own facts.

Wonderful drone photo at the top of the post. Scale, north point ?
Pothole grinding is equally likely caused by some sandstone shards that were more heavily infused with iron oxides in the pore spaces of the bedrock. Commonly called “ironstone”, these patches are scattered throughout the bedrock from overlying palaeoleaching of extrusive volcanics – mostly. Basalt shards may have also been the grinders.
The fracture sets are NE-NW jointing with superimposed E-W fractures, perhaps from later tectonics. To determine that, location is helpful. There is suggestion in the photos of the tree lines following the NE joint line as that is likely where the soil accumulated most heavily. I’ve seen growing eucalypts root-anchored in such joints on bare rock exposures – one such tree had actually shunted a large sandstone block aside as its’ trunk grew in girth, with the slickensides from the moved block quite evident.
All hard evidence of sea level drop from the Holocene highstand. The mean rate of drop could perhaps be estimated by examining the remnant tree line. Soil (even poor sandy soil derived from sandstone weathering) cannot accumulate under constant tidal washout of bare rock, nor can that plant species survive if the soil is constantly washed away.
Fear of becoming a sceptic pariah…never a truer word said
The youth of today, as indicated by the lack of interest by your young relatives in your work, seem to have little or no idea of the real world.
It’s so sad, and it bothers me that their future is being directed by their elders upon whom they trust to do the right thing; but, sadly not. The Pope’s call to action in May 2020 has all the hallmarks of a giant propaganda exercise to further entrench the ignorance of the youngsters of today. What hope have they got to learn the truth?
Thanks Jennifer. I did watch your lovely film on Beige Reef, and as far as l’m concerned you most certainly proved that the reef is looking exceedingly healthy.
I’m a bit of a reef freak. In fact l’ve been to many different reefs, including Fiji (hundreds), Cook Islands, Solomon Islands, Bali (various), and a multitude of others, including the Red Sea, Hawaii, etc.
I’ve dived and snorkeled various locations along the GBR, and rarely have l witnessed extensive coral bleaching. I’ve seen bleaching, but more often than not l have seen extraordinarily healthy corals alongside, or in close proximity.
l struggle to understand what all the fuss is about, as I’ve been snorkeling and diving reefs, for close on 43 years, and although bleaching definitely occurs, the corals eventually recover. Most of the damage l’ve witnessed has had far more to do with cyclones!
AGW is such a con job, and in reality has nothing to do whatsoever with Climate. The UN and it’s IPCC, and the various NG0’s pushing this nonsense are getting desperate, and l’m getting that feeling that it’s going to end in tears soon. I believe the demise the climate Hoax was cast in stone when Trump made his decision to exit Paris. China will be forced to follow, and then India. This represents close to half the worlds population.
Keep up the good work Jennifer.
Cheers
Ta Jennifer. I reckon it’s just as well nature/climate/weather has taken it’s own course, otherwise we would be contending with dinosaurs!
I look forward to each point you make. I appreciate your leadership and education.
People are scared of being unpopular and the aggressive spiteful attempts at personal attack when the (most popular) belief is challenged. My own mum was a biologist and librarian… she taught me to question everything.
Thanks for your excellent work. I have shown your work to university students for 10 years or so. They only watch or read if I made them. It is frustrating that folks don’t watch films we have made, papers we have written. Just a thought about a typo: “I know that there is fear within the varies communities within which I exist, of at least three” should be various.
Thanks Jen. Yes, sea levels are falling. The BoM’s actual records show current Mean Sea Level at Fort Denison, Sydney Harbour, to be over 4 inches [113mm] LOWER than their first recording 105 years ago:
http://www.bom.gov.au/ntc/IDO70000/IDO70000_60370_SLD.shtml
This is where the world’s oceans are at their widest and this recorded MSL fall is supported by the increase in area of atolls throughout the Pacific.
When AGW is proved to be a scam, and I am sure it will be, I would expect the proponents of the scam to be sued for the billions/trillions wasted.
Scientists will have to be struck off.
Fraud is surely involved.
The Minoan Warm Period was about 3300 years ago. The high stand 6000 years ago was during the Holocene Climatic Optimum, which ended around 5200 years ago.
Keep up the good work, Jen! Your Beige Reef video was excellent and told a compelling story. It is too bad the close-minded dolts in the media and politics refuse to accept the truth of things.
When I was a grad student on the east coast of the USA back in the early eighties, all the talk was about rising sea level causing “barrier island rollover.” Those pushing this theory based their careers on this erroneous idea. And I admit it was a seductive theory until I really looked into it deeply. Now that these guys are at the ends of their careers and lives they continue to hold onto the same lame theory. While I feel sad for their plight, I also recognize that they brought this on themselves by refusing to look deeper. Had they really made an effort to study the coast they would have soon realized that subsidence along the east coast of North America mimics RSL. In Florida, where I studied, the so-called barrier islands are nothing of the sort, they are mainland beaches cut off by the building of the Intracoastal Waterway in the 1920s. I discovered this while working with aerial photos of the entire coastline. If one is willing to look and observe the truth of what is going on often reveals itself.
Today I work as an Independent Researcher based in northern Portugal and owe nothing to anyone so can freely speak my mind without fear of losing funding or being fired. The CAGW clowns have built themselves a huge sand castle and I think the tide is now coming in, hopefully a King tide! It will undermine the foundations of their foolish hypothesis about CO2 driving the climate and many careers will end up stranded on the berm when the water recedes….
The good thing about the Australian continent is that in the last 10,000 years it has been relatively stable compared to Europe and North America, which were both extensively covered by very thick ice sheets that depressed the land surface, which is now slowly springing back.
It makes these more recent sea level movements (since the end of the last ice age ca. 12,000 years ago) much easier to see in the coastal morphology.
Thank you Jennifer, another well presented article !
I do fear for the younger generation though who now actually know nothing except for the lies being spread by almost every media outlet, TV and pop personalities who are their gods unfortunately, and even the religious icons now getting involved in things they know nothing about.
I also fear for the parents of the younger generation who should know better. Except I reflect on their education which I now recall when my children were in high school some 10 years ago now and I cant remember a time when they were taught to challenge and do research on topics for their science projects as we were taught to do when I went to school in the 60’s and studied chemistry and biology in the 70’s. we did our own measurements for all our own projects and experiments, reported the errors and stats on them and made our inferences and conclusions around that data. Always challenging the norm and making sure we reported honestly and openly all of our raw data along with the reports.
Now they just seem to listen to the extremists and follow like sheep. no questions asked. Teachers (or should I say facilitators ??) alike. When I talk to young people about AGW they all sound like robots programmed from the same algorithms. SCARRY !
I believe it all started with dumbing down the education system and taking away the ability to question and and think “This doesn’t sound right”?? is there something missing or incorrect in what i am hearing and seeing ??, “That is the Question !” and ‘Why Is It So?’, (Professor Julius Sumner Miller). one of my childhood icons who I have never forgotten, and also The summer science school series, Professor Harry Messell.
these guys knew how to think, how to teach thinking and how to present facts, physics and THINKING !.. Sadly this is not taught in universities or schools anymore. That really saddens me.
Except for a few of us left and especially you Jennifer. keep up the great work.
ps I loved the vid. one day, it will be part of the great hoax exposure, but I think it will take a long time yet to get to critical mass proportions,,However, I do see the tide turning so lets keep up the good fight and and I will keep plugging away whenever I can in my circles.
It’s sad and depressing that your own relatives won’t (or at least haven’t) watch your film due to fear of, well, no longer being afraid.
I’ve always found it confusing and unnatural. When people think something bad is going to happen, aren’t they normally happy and relieved when there’s evidence that the bad thing won’t happen? Yet in the global warming/climate change arena, believers viciously attack anyone who brings good news that the thing they allegedly fear so much is not going to occur.
Is there any chance you could arrange a family get-together for the purpose of watching your film? Perhaps you could allay some of their fears.
Jennifer, even their clueless ABC get it right occasionally and in this Catalyst program they tell us that just 4,000 years ago sea levels on our east coast were about 1.5 metres higher than today. Here’s their quote from the Catalyst program. This is nth Sydney where the aboriginal remains were found. Here’s the link.
https://www.abc.net.au/catalyst/narrabeen-man/11010512
Dr Macdonald:” The date came back at about 4000 years ago, which was quite spectacular we were very surprised.
Narration: 4000 years ago when Narrabeen Man was wondering around this area the sea levels were up to 1.5 metres higher than they are today.
Paul: So that spit would have been much narrower. The water levels in the Narrabeen lagoon would also have been higher and it would have acted like a saline estuary”.
Jennifer here is more on Spangled Drongo’s link to BOM’s MSL data at Fort Denison.
Here Andrew Bolt talks to Daniel Fitzhenry about the 1914 to 2019 BOM MSL data and this is the covering story below the video.
“Hydrographic Surveyor of NSW Australia Daniel Fitzhenry says data recorded by the Bureau of Meteorology at Fort Denison in the Sydney Harbour is “more accurate than satellite” on sea levels”
Here’s the video link from the Bolt Report. I hope Jennifer has the time to watch it. All the best for 2020 Jennifer and let’s hope somebody in govt starts to wake up to their silly mitigation fra-d and con trick. IMO Craig Kelly is the best chance to make a difference, if Jennifer has the time to even carry out a phone interview and try to swap ideas with Craig?
Craig seems to be well up on the science and perhaps an interview for Jennifer with Alan Jones or Bolt or Credlin or Murray on Sky news could be arranged? Here’s the Fort Denison link.
Sea level was how I first discovered the sceptics’ arguments, via the late, great John Daly’s site.
I am forever grateful for my scepticism of this scam. It truly is like walking around and seeing so many people wearing the Emperor’s New Clothes. Scary, yes and sometimes a little depressing, but I wouldn’t swap my clear sight on the issue for anything.
I grew up in WA where up and down the coast one sees stranded wave cut platforms, evidence of higher sea levels in the very recent (historical times, less than 10,000 years) past – very similar to your example from SE Qld. Concur with with your interpretation re the pothole features – can only occur in the high-energy, littoral zone in normal tide range.
Jennifer, Willis Eschenbach has another interesting post at WUWT and looks again at some of the recent projections about the future.
Some of these have been complete failures and have been found to be wrong in a very short time.
But he does look at the Greenland temp again over the last 12,000 years and finds no correlation with increased co2 emissions.
In fact co2 has been rising for the past 7,000 years while temp has been falling over that time.
See Vinther et al study linked at the post and their last Holocene graph showing co2 and temperature.
So where is the melting ice to come from to give us our dangerous SLR by 2100 and beyond? According to satellite data UAH V 6 there has been no warming on Antarctica over the last 41 years, so that doesn’t help either.
Anyone have any ideas? Here’s the link.
https://wattsupwiththat.com/2019/12/27/failed-serial-doomcasting/
Thanks Jennifer for this great post.
Real science by a real scientist !
Good photos. There’s plenty of evidence for sea level fall over past 800 to 1500 years: NSW, NT, and Qld coasts have dried coastal lagoons, receding beaches, old wave platforms, old mud flats and flood plains now a metre above high tide (Townsville, Bowen, Port Alma). Also the Albrolhos off WA coast. We are experiencing long term global cooling.
So much thanks to Charles at WUWT for reposting: https://wattsupwiththat.com/2019/12/27/what-can-you-see-indicating-sea-levels-are-rising/
Of course, lives and livelihoods are threatened by all of this nonsense and careers destroyed.
I made the film ‘Beige Reef’ because back in 2016 Peter Ridd was censured by James Cook University for questioning what quality assurance was in place regarding claims about the supposed death of the Stone Island corals. Peter’s further statements about quality assurance in 2017 result in his sacking.
At that morning tea, under a shelter at Coolum Beach, none of my nieces or nephews or older brother could admit to having watched the film.
I watched it twice.
Here Andrew Bolt has a very interesting editorial from the Bolt report Oct 2019.
This is one of his best covering clueless Labor’s climate emergency stunt in parliament on that day.
And a few minutes into the video he shows 2 photos of Balmoral beach Sydney in 1905 and today in 2019, with emphasis on a circled flat rock in both photos.
The photos showing the rock over a period of 114 years are identical with little change that can be noticed. Check it out for yourselves and see if our so called dangerous SLR makes any sense to you at all.
But Bolt is right, Labor is deaf and barking mad.
https://www.heraldsun.com.au/blogs/andrew-bolt/climate-emergency-is-labor-deaf-or-mad/news-story/978692e7d63f13cb3d41ecdca136a451
Here’s that Bolt video again direct from You tube. Perhaps it may allow more browsers to select full screen to look at the two Balmoral beach photos in more detail?
Your ‘research’ is mindblowingly simplistic. You cannot measure global sea level trends by visual observations at your local beach. There are fluctuations in sea levels around the globe caused by a multitude of factors (mostly land influenced). In some places seas will be lower. The evidence of sea level rise has been conducted through thorough, replicated, peer reviewed, internationally recognized research. Please people, dont fall for this rubbish.
Here is the latest Duvat 2019 study of Coral atoll islands and this supports all the other recent studies that show about 87% of islands are either stable or growing in size.
The recent Kench studies etc also support these findings. Charles Darwin reported on this over 160 years ago and yet today we still find their ABC and other MSM extremists trying to con people into thinking these Island states are in extreme danger from SLR.
https://onlinelibrary.wiley.com/doi/full/10.1002/wcc.557
Here’s Dr Ole Humlum’s 2019 report to the GWPF and he finds an average Global SLR at the tide gauges of about 1 mm to 1.5 mm a year or 3.2 inches to 4.8 inches by 2100. If this was the case this would be less than the SLR over the 20th century. But satellites after adjustment show about 3.1 mm a year, or about 12 inches SLR by 2100.
Here’s his quote from the report and link to the report below. See page 38.
“Data from tide gauges all over the world suggest an average global sea-level rise of 1– 1.5 mm/year, while the satellite-derived record (Figure 30) suggests a rise of 3 mm/year, or more. The noticeable difference (at least 1:2) between the two data sets has no broadly accepted explanation”.

Hi,
I came across this site and had a look at the Bom Fort Denison Data.
Average for 1914-1923 is 0.913m
Average for 2010-2019 is 1.008m
Increase is therefore 9.5cm
http://www.bom.gov.au/ntc/IDO70000/IDO70000_60370_SLD.shtml
Happy to show people how its done, nothing fancy just a 10 year average.
Jennifer
Great post this and the post on the coral reef.
Harlech Castle in North Wales has a sea gate for the delivery of supplies. The castle was constructed circa 1285.
The sea gate is now approximately one kilometre from the sea. The area between is a golf course. I’m not sure this is relevant but given the topography I think it unlikely to be re-claimed land.
Happy New Year
Here’s an interesting article about the time after 2010- 2011 when Australia was able to change the satellite GLOBAL MSL graph.
So much water was contained within the continent because of very heavy rainfall from la nina+ negative IOD events that the global MSL graph had a pronounced drop ( gully) for more than a year.
It just proves that we can have major floods and droughts in Australia over a short period of time. Don’t forget that 2016 was also a MDB flood year because of another negative IOD.
There is a link to the Uni Colorado MSL graph below showing the big drop after 2011.

Sally says:
“You cannot measure global sea level trends by visual observations at your local beach.”
Sally, over a long period of time this is the most factual way of observing what sea levels are really doing.
For example, when I observed fine weather king tides [at around normal barometric pressure, not cyclonic] from 1946 to 1953 coming just over the top of our sea wall and trickling into our well [if we didn’t keep a levy bank around it] and for the last 10 years those normal BP king tides are up to 250 mm LOWER than 70 years ago, there is no better data than that to advise me that sea levels are not rising.
When I see our ocean beaches wider than they have been in my lifetime and ocean-front houses that we struggled to save from washing out to sea now changing hands for tens of millions when you couldn’t give them away back then, that is very conclusive evidence that sea levels are not rising.
Why is it that many of the main promoters of the “climate crisis” are very wealthy people but are still perfectly relaxed in spending a large part of their fortune on sea-front mansions?
Do you think they really believe alarmist sea level predictions?
Dr Marohasy, you ask where to get facts about sea level rise. May I suggest you start with peer reviewed science based on actual collection and analysis of data, such as the following:
White, Neil J., Ivan D. Haigh, John A. Church, Terry Koen, Christopher S. Watson, Tim R. Pritchard, Phil J. Watson et al. “Australian sea levels—Trends, regional variability and influencing factors.” Earth-Science Reviews 136 (2014): 155-174.
To quote just one paragraph from this paper:
“Gehrels et al. (2012) used sea levels recorded in salt marsh sediments to infer sea level was stable in the Tasmanian and New Zealand region, at about 0.3 m lower than at present, through the middle and late Holocene up to the late 19th century. The rate of sea-level rise then increased in the late 19th century, resulting in a 20th century average rate of relative sea-level rise in eastern Tasmania of 1.5 ± 0.4 mm yr− 1. This, and other analyses (e.g. Lambeck, 2002, Gehrels and Woodworth, 2013) suggest an increase in the rate of global and regional sea-level rise in the late 19th and/or the early 20th Centuries. The earliest known direct measurements of sea level in Australia are from a two-year record (1841–1842) at Port Arthur, Tasmania relative to an 1841 benchmark (Hunter et al., 2003). Hunter et al. (2003) estimated a sea-level rise over the 159 years to 1999–2002 of 0.135 m (at an average rate of 0.8 mm yr− 1). If, following Gehrels et al. (2012), most of this rise occurred after 1890, the 20th century rate would be 1.3 mm yr− 1, or 1.5 mm yr− 1 after correction for land uplift (Hunter et al., 2003 and Hunter pers comm).”
I assume you have robust arguments (perhaps even a published paper) which demonstrates the above points are wrong, and in fact sea levels are now falling?
Jennifer,
Happy New Year.
When the reactionary trolls who have not read your work do drive by comments that only shot their ignorance, it is clear you are doing a good job.
Best wishes for a very successful and happy 2020!
Peter Cook
You are quoting rates of at most 1.5 mm per year increase over the last 100 years? So, this is equivalent to 150 mm in total over the last hundred years or 0.15 metres?
There are cycles within cycles, generating oscillations within bands, when it comes to everything to do with climate. So, there may be some cycling-up over the last 100 or so years of around 15 centimetres in total? I thought the IPCC was quoting a value of more than double this: about 36 cms?
This is not inconsisent with the longer term trend of sea level fall since the Holocene High Stand which some claim to be 4,500 years ago, others closer to 7,000 years ago. This longer term trend — that we can see with our eyes and also is supported by the technical literature — suggests an overall fall in sea levels of about 1.5 metres.
I was recently sent this note with a list of technical papers. I actually have some more, and more recent reviews of Holocene sea level fall. If you would like I can email them to you. Let me know.
****
Note from Howard Brady from some months ago:
There is evidence of a gradual fall (not rise) from a high sea level stand between 8000 and 2000 BP. Such evidence comes from an increasing number of peer-reviewed articles describing evidence of this high sea level stand and its decline along the coasts of Australia, South Africa, South America, South Korea, and Vietnam. There is increasing evidence that such a wide occurrence of a high sea level stand, especially in the Southern Hemisphere, cannot be interpreted as due to crustal movements (Glacial Isostatic Adjustments -GIAs) in different continents at the same time as these areas did not experience any significant glacial or ice crustal loading during the last ice age advances. Basically, there is now so much data on this fall in sea level from a high-level stand that the GIAs quoted by Dutton and Lambeck 2012 should be abandoned. A few references to peer reviewed articles describing a high sea level stand in the HTM and the fall in sea-level from 8000 -2000 BP are listed below. There is no justification for any glacio-eustatic uplift since 8000 BP that stopped (for some unknown reason about 2000 BP) in regions that did not experience any ice loading during the last glaciation.

A happy and prosperous new year to everyone. But in reality we’ve just lived through the most prosperous decade in human history.
I know this won’t be what the extremists or con merchants want to hear but it’s the truth whether they like it or not.
Matt Ridley lists some of the facts for everyone to understand, but I’m sure the usual eco-loons and Greta luvvies will twist and turn until they convince themselves that he must be wrong.
See his list of sources at the link or check Our World in Data or UN or Dr Roslings Gap minder etc. Lomborg is another source.
BTW check out our rapid prosperity from 1810 to 2009 after we had the sense to start using fossil fuels. Thanks to Dr Rosling and his team allowing anyone who has a few minutes to spare to understand how far we’ve come in just 200 years.

Here is Dr Rosling’s 200 year video.
Thank you Dr Marohasy for that information. I am still not sure whether your position is that you accept (or reject) that there has been sea level rise since the start of the industrial revolution.
The 2016 Donchyts et al study found that since the 1980s coastal land was increasing all around the world. This was due to exact measurements by satellites over that period of 30 years.
This was surprising after we’d been told for years that the seas were rising and would eventually impact and flood more coastal areas across the globe.
Here’s the BBC report on the study and the data and measurements directly from the satellites.
The BBC link is worth a read.

“Earth’s surface gained 115,000 km2 of water and 173,000 km2 of land over the past 30 years, including 20,135 km2 of water and 33,700 km2 of land in coastal areas. Here, we analyse the gains and losses through the Deltares Aqua Monitor — an open tool that detects land and water changes around the globe”.
Hi Peter
My position is that there are many different phenomena that affect sea level, most of them extraterrestrial in origin.
The longer-term most significant trend obvious in the cliff faces and wave cut platforms along the shore line here at Noosa indicate sea level fall of more than one metre since the Holocene High Stand. That there has been a rise of perhaps 36 cms since the early 1800s, coincident with the Industrial revolution, is not particularly remarkable and does not change the fact that the longer term trend is one of fall.
It is also the case that there will be a measurable rise in the sea level at Noosa of about 80 cms tomorrow between 6am and lunch time, followed by a fall of a similar amount. This is part of the daily cycle that sits within the monthly cycle that sits within the 18.6 year lunar declination cycle, and so it goes on.
Can you tell me what caused the 120 metre rise in sea levels globally that began about 20,000 years ago and continued until about 7,000 years ago?
Many sceptics and alarmists like to suggest that sea levels have continue to rise through the Holocene (over the last 10,000 years) but this claim is not supported by the technical literature or what I can see along the east coast of Australia.
There are cycles within cycles, I think the fall since the Holocene high stand the most significant for those interested in climate change, and the most denied … but if you are going fishing it is the daily cycle that will be of most concern to you, perhaps.
