When Samuel Hearne was there, he chiseled his name above high water. With Isostatic rebound the bottom of the cove is now ~4 feet above high water. Not the ocean level dropping.🤣🤣🤣

GRAFFITI... ok.

You might want to try being informed, not just opinionated.
FWIW: The only difference between being uninformed and misinformed, is that one is your choice, and the other is theirs.

The water levels at the local pier appear to have simply not changed. If the sea levels have risen 9" then the lower landings would be at or just under sea level... and the simple fact is that 67 years after I played in the waters here, there is NO measurable rise in water levels at all.

I have to wonder whether these "islands in the Pacific" etc are sitting on tectonic plates that are sliding down, hence flooding these islands.

Using Venice as proof of rising seas is totally lying because Venice sits on a plate that is definately sinking, as it has been doing for centuries now.

Miami Beach is sinking a lot. Some say its because of all the New Yorkers arriving fleeing violent crime in NY. NOAA sez rise is 5 3/4 inches on USA east coast in past 100 years from 1919 to 2019 measured from their Geodetic benchmarks.

Small increments of sea level rise become big problems along world coastlines

Due to competing predictions of future global temperatures, scientists are unsure exactly how fast or high sea levels will rise.

But they all agree on its impacts: submergence and flooding of coastal land, saltwater intrusion into surface waters and groundwater, increased erosion, and overwhelmingly negative social and economic repercussions. They are also clear that these effects will be widespread, and will accelerate with time.

Since many coastal cities are built on mangroves and swamps, some of the world’s biggest cities are sinking, at the same time as seawater is rising. This is not just because they are heavy, but also because their residents are extracting vast quantities of groundwater.

Even in the unlikely event that global temperatures are kept from exceeding two degrees Celsius, by 2050, close to 600 coastal cities with over 800 million residents will be ravaged by rising seas and storm surges, water salinization, and an unfathomable financial burden.

According to data produced by Climate Central [1], which uses a new digital elevation model, CoastalDEM [2], to better project annual flood levels, rising ocean waters will completely inundate many coastal land areas, within the next three decades.

Here are just some of the places, around the world, that could be underwater by 2050, if major steps to prepare for rising seas aren't taken:
Bruges, Belgium
East Anglia, UK
Delft, the Netherlands
Ribe, Denmark
Tabasco, Mexico
Panama City, Panama
The Bahamas
Bangkok, Thailand
Ho Chi Minh City, and Hué, Vietnam
Venice, Ravenna, and Aquileia, Adriatic Coast, Italy
Thessaloniki, Thermaic Gulf, Greece
Andalucía, Spain
Alexandria, Egypt
Port Douglas, Australia
Tuvalu
Kuching, Malaysia
Mumbai, and Kolkata, India
Shanghai, China
Manila, Philippines
Maputo, and all Coastal Mozambique
Churchill, and all Hudson Bay, Canada
Charleston, SC, USA
St Augustine, FL, USA
All Florida Keys, USA
New Orleans, LA, USA
San Francisco Bay Area, USA

List doesnt include Wash DC but includes all of SF Bay area which is very hilly and far above current sea levels. So its BS.

My listing contains "... just some of the places, around the world, that could be underwater by 2050 ...".
You might want to peruse the Primary Sources, I cite. My layman's summaries, only intended to give a very brief description, will be a poor representation [& to that extent, perhaps BS] of the expert information therein.

That could be part of it but mostly fleeing the leftist tax em to death ideology.

But the majority is from the following
1) groundwater removal
2) isotastic adjustment.

'Don’t Look Up’: Hollywood’s primer on climate denial illustrates 5 myths that fuel rejection of science

The satirical film "Don’t Look U"p, in which an asteroid stands in for the threat of climate change, handily demonstrates the myths, that bolster science denial, write research psychologists Gale Sinatra, and Barbara Hofer.
They spell out five misconceptions to watch out for — and how to combat them.

Tounge in cheek?

By the way, Port Douglas mentioned in a flooding list in a previous post, is a seaside holiday town in North Queensland, Australia.

When I visited their the 1st time in 1970 it was possible to drive on the beach with a 30km/hr speed limit... today there are so many tourists that vehicle access is no longer permitted.

This beach looks NO DIFFERENT as far as water levels go than it did 51 years ago... and in 30 years it will look exactly the same no doubt.

Or this fort in I think Sydney harbor .

If I recall correctly. The shot on the left was in the early 1900's. Or even late 1800's
Second one is within last 20 years.

And with more than a 1 meter tide range the pic were of course taken at the same tide.

Look at the high tide growth on the bastion walls . It has not changed .

Indigenous communities, along Canada's Atlantic coast, at risk from rising sea levels

First Nations communities along the Atlantic coast may face grave challenges from climate change, a recent federal report [1 & 2] says.

The Regional Perspectives Report: Atlantic provinces [2] said Esgenoôpetitj First Nation, about 130 kilometres north of Moncton, was already at risk for flooding, but climate change, and rising sea levels, may intensify flood risks for the community, and intense storm surges have increased erosion.

Esgenoopetitj, Ugpi'ganjig, Indian Island, and Lennox Island First Nations were named, specifically, as communities facing significant challenges from climate change, but all coastal communities are at risk of flooding.

Indian Island, and Ugpi'ganjig First Nations have already been hit with violent storm surges, that caused flooding. In December 2010, Ugpi'ganjig experienced a storm that caused over $1.7 million in damages, and responded by constructing a concrete seawall, and other flood prevention measures. Indian Island First Nation also built a seawall, and began elevating homes, in the last five years.

Historically, Mi'kmaq moved seasonally, and, if faced with increased flood risk, would have moved inland. But the reserve system forced them to stay put.

The loss of land, from coastal erosion, is minor, for most communities, but Ugpi'ganjig, a coastal community situated along the Eel River, and the Bay of Chaleur, is at higher risk. A dam, built in the 1960s, caused changes in sediment distribution, destroying sandbars, and increased erosion led to the loss of 24 hectares of land, which in turn increased the community's flood risk.

The report [2] said there are plans to increase flood preparedness in Indigenous communities, like improving drainage systems, and raising and fixing flood damaged homes and other infrastructure.

The P.E.I. Department of Environment, Energy and Climate Action said it sent letters to First Nation chiefs about consultation on a climate adaptation strategy.
The New Brunswick government said it has provided funding to First Nation communities facing climate change, through the Environment Trust Fund, and will continue to engage with them.
Newfoundland and Labrador said it will continue to work with Indigenous communities impacted by climate change.

The Regional Perspectives Report, led by Natural Resources Canada, provides regional perspectives on how climate change is impacting our communities, environment and economy, and how we are adapting. The report provides decision-makers with an assessment of current literature and knowledge on climate change impacts and adaptation, including case stories that feature examples of adaptation in practice. Each regional chapter discusses on key vulnerabilities, risks and challenges; new and innovative approaches to adaptation; Indigenous knowledge and perspectives; capacity to adapt to climate change impacts; and knowledge gaps and emerging issues. Chapters from this report will be released on a rolling basis during 2020 and 2021.

So if I read this correct the indigenous peoples normally nomadic but due to the Canadian government intervention . what would have been non issues now is a considerable risk item.
Gotta love government intervention
