Sea level has risen 8–9 inches [21–24 cm], since 1880, with about a third of that coming in just the last two and a half decades.
In 2020, global mean sea level was 3.6 inches [91.3 mm] above the 1993 average, making it the highest annual average in the satellite record [1993-present].
From 1993 -to- 2020, Global Mean Seal Level Rate of Change has been +0.134 inches [3.4 mm] per year.

Since you [newhaul] are so fond of unattributed graphs:

I see an actual significant issue with the graph as posted it contains falsified data .

Where is the 7mm drop in sea level that occurred in 2010/2011 Australian summer rainy season?

Really and what does that have to do with the rise and fall of sea levels?

Misdirection hyperbole?

Please if you have anything to actually add to the discussion at hand present it .

Looks like a TerraPower design like Gates was developing in China before Trump said to stop giving China out proprietary technology.

These statistics are total B***S**t.

I was born in a seaside village in 1947 and spent my childhood on the shores and in the water... swimming, sailing and fishing... and gathering shellfish, worms and one arm bandits for fishing bait.

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.

You don't say where that is, but maybe your little spot is rising.

The average sea level rose at a rate of 13.3 centimeters per century at Prince Rupert, 6.6 centimeters per century at Victoria, and 3.7 centimeters per century at Vancouver. In contrast, the average sea level fell at Tofino at the rate of 12.4 centimeters per century. Variation in sea level change between the four B.C. sites is largely explained by different amounts of vertical land movement.


Here it's happening in your back yard as well . Tofino actually saw sea level decline .

It's just another thing you haven't noticed. [It's a matter of chart scale, NOT fraud]

Here it is:



The anomalous drop in GMSL [2010/11] is UNDISPUTED by scientists [sorry, no ‘gotcha’].
According to NASA [not just newhaul & the Guardian], from mid 2010 to mid 2011, global mean sea level (GMSL) dropped by ~5 mm.
➥ https://podaac.jpl.nasa.gov/DataActi...-08-GRACE-GMSL

Newhaul’s Guardian article refers to this paper:
“Australia's unique influence on global sea level in 2010–2011" by John T. Fasullo et al
➥ https://agupubs.onlinelibrary.wiley....1002/grl.50834

”... Since 1993, satellite altimetry has provided an estimate of the background rise in sea level of about 3 mm yr−1, while resolving interannual variations of several millimeters...
... However, beginning in mid-2010, an anomalous drop in GMSL that was unprecedented in the altimeter era began, reaching a low of about −7 mm in early 2011 and persisting until late that year. Strong agreement on both the magnitude and timing of the drop was reported across processing centers. Boening et al. [2012] examined GRACE and ARGO fields during the drop and demonstrated that closure in the surface mass budget was achievable to within the error bounds of ocean heat content estimates...”

If science is so good at recording and "proving" mean average sea levels are rising, WTF can't they include the mean average land mass rise and fall as well?

HUH?

Just asking?

There is ONLY one truely honest and unbiased way of settling this, and that is by measuring "Volume" of water on the surface of our rotating rock.

NOBODY takes into account the fact that sea levels in Iceland are dropping exceedingly fast, because that would make "science" recognise that the places that they use to measure sea levels are suited to their stupid "Global Warming" narrative.

Where is the link to support this?
Well!

They can, and do.

Scientists, who study changes in Earth’s size and shape [geodesists], have long measured vertical land motion, with inexpensive ground-based tools. But in the Space Age, satellite-based techniques [the Global Navigation Satellite Systems (GNSS), and synthetic aperture radar (SAR)] have revolutionized geodesy,l by making it possible to study Earth’s changing shape, including subsidence and uplift, on a global scale, and in three dimensions.

➥ https://uavsar.jpl.nasa.gov/educatio...is-uavsar.html
➥ https://nisar.jpl.nasa.gov/

Through the use of two other pioneering geodesy techniques: Very Long Baseline Interferometery, and Satellite Laser Ranging (SLR); scientists have also gained key insights about the way land rebounds [Glacial Isostatic Adjustment], after the melting of large volumes of ice from Earth’s surface.

FWIW: Global mean sea level trends, are calculated, relative to a fixed place on land.

1. Iceland is rising rapidly, in some locations, which affects the relative sea level change. In some locations, especially along the south east coast of Iceland, the rate of rise is so fast that it is doubtful that these locations will experience any sea level rise.
➥ https://www.icelandreview.com/news/l...ting-glaciers/

2. The current size (and mass) of the Greenland Icesheet affects gravity, around it, in such a way, that it keeps sea level higher than otherwise. Once the Ice Sheet melts, this effect diminishes, with the result that sea level may drop, close to the ice sheet, but rise more elsewhere.

... but the "Fixed Place On Land" is constantly rising and falling relative to "other" fixed places on land.

A little bit North of Me, is Sloop Cove.





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.🤣🤣🤣

Let us face it... the seafarers amongst us don't give a flying fig about sea levels, other than changes in tides on a daily, weekly or monthly basis.
