New Zealand Sea Level Change

[GordMay]

New Zealand faces major sea rise ‘much sooner than we thought’

While the global sea level is expected to rise 5 metres by 2100, for large parts of New Zealand, it could be 1 metre, because the land is sinking too, due to the movement of tectonic plates.
A huge new public data set shows many communities are sinking, speeding up the effects of sea level rise.
A lucky few are rising, making for wildly varying situations around the coast.
While much of the country is sinking, including Auckland, Wellington and parts of Christchurch, there are places like Tauranga and the small community of Pīkowhai that are actually rising.
Another observation from the piece, based on research for former parliamentary commissioner for the environment Jan Wright, finds that just 30cm higher seas would turn a one-in-100-year flood event in Wellington into an annual event.

NZ SeaRise
The NZ SeaRise: Te Tai Pari O Aotearoa programme has released location specific sea level rise projections out to the year 2300 for every 2 km of the coast of Aotearoa New Zealand. These projections can be accessed through a new online tool developed by Takiwā, a data management and analytics platform.

“Carbon dioxide now more than 50% higher than pre-industrial levels” ~ NOAA June 3/22
Concentrations of carbon dioxide in the atmosphere in May [450+ ppm] were 50 percent higher than during the pre-industrial era, reaching levels not seen on Earth for about four million years, the main US climate agency said on Friday.

NOAA's measurements of carbon dioxide at the mountaintop observatory on Hawaii’s Big Island averaged 420.99 parts per million (ppm), an increase of 1.8 ppm over 2021. Scientists at Scripps, which maintains an independent record, calculated a monthly average of 420.78 ppm.

Last May, the rate was 419ppm, and in 2020, 417ppm.

Before the Industrial Revolution, levels of CO2 held steady at about 280 ppm, a level maintained for approximately 6,000 years of human civilisation, that preceded industrialisation, according to NOAA.
The current level is comparable to what it was between 4.1 and 4.5 million years ago, when CO2 levels were near or above 400ppm. At that time, sea levels were between five and 25 metres, higher than now.

Not just N.Z.

According to NASA’s “2022 Sea Level Rise Technical Report”*:

1. Sea level along the U.S. coastline is projected to rise, on average, 10 - 12 inches (0.25 - 0.30 meters) in the next 30 years (2020 - 2050), which will be as much as the rise measured over the last 100 years (1920 - 2020).
Sea level rise will vary regionally along U.S. coasts because of changes in both land and ocean height.

2. Sea level rise will create a profound shift in coastal flooding over the next 30 years by causing tide and storm surge heights to increase and reach further inland.
By 2050, “moderate” (typically damaging) flooding is expected to occur, on average, more than 10 times as often as it does today, and can be intensified by local factors.

3. Current and future emissions matter. About 2 feet (0.6 meters) of sea level rise along the U.S. coastline is increasingly likely between 2020 and 2100 because of emissions to date.
Failing to curb future emissions could cause an additional 1.5 - 5 feet (0.5 - 1.5 meters) of rise for a total of 3.5 - 7 feet (1.1 - 2.1 meters) by the end of this century.

4. Continuously tracking how and why sea level is changing is an important part of informing plans for adaptation. Our ability to monitor and understand the individual factors that contribute to sea level rise allows us to track sea level changes in a way that has never before been possible (e.g., using satellites to track global ocean levels and ice sheet thickness). Ongoing and expanded monitoring will be critical as sea levels continue to rise.

have no fear, fair cruiser..
..and no need to worry.

the accuracy of projections from climate "experts" would actually improve if they were simply stating "facts" randomly.

their purpose appears to be fear mongering..
...and nothing more.










this is not to say that climate does not change...
it does... and that is ok.

at no point in earth history has there be a time where there was not "change"
we do have seasons..
places like greenland doesnt appear to have always been covered with a mile thick sheets of ice.


which is ok..
we survived everything single thing this planet threw at us. (humans..are like undefeated, right?)

which projects to us doing the same (winning) for eternity





so why worry?

Past performance is no guarantee of future results.

Nonsense, as usual.

Indeed!
SEC Rule 156 requires mutual funds to tell investors not to base their expectations, of future results, on past performance, before they invest.

“Reality is an Acquired Taste.” ~ Robert Fritz
“Imagination creates reality” ~ Richard Wagner

“Don’t let your imagination create your reality” ~ Gord May

The hard to follow phrase “alternative facts” has entered into the public dialog, as if “my truth, and your truth” became the new norm, and objective reality, an obsolete relic of the past.

Reality is not in the eyes of the beholder. Reality is the actual condition, whether we see it or not.

Seeing reality for what it is, is a discipline. It is a developed skill, and it takes ridding ourselves, as Rene Descartes said, of all preconceptions.

It is hard to see reality when you are busy defending a belief system, or supporting a concept, or an ideology, or some other cause.

This has been the strategy, for years, in cults, weakening reality as a credible source, so as to impose the cult’s belief system. But reality will be what it is, REAL, no matter if it is perceived or not. It makes one long for the wisdom of Gertrude Stein: “A rose is a rose is a rose.”

Is sea level rising.. or is land level on certain plate edges sinking...

Science isn't "would of, should of, could of" hypothetical nonsense. But it does play well to the easily frightened among us.

true...
(but dont it was implied that there were any guarantees)

...but would you consider the past performance IS useful in decision making for future?


(of course you would...and do)


for example...i love tacos..
while i'm open to try new places...
do i tend to return to the places where i've had really really good tacos previously? (and avoid those serving the not so good)
heck yeah i do.. and so would every other human on the planet.





going by memory..
but i remember a study froom the UK that estimated (up to)1:14,000 odds of extinction every year (or an extinction event roughly every 14,000 years or so)


so even if that is true..
WE are still here.
...so my point stands.
we (as a species) have survived EVERYTHING in history (which is proven by the fact we exist this moment)


there is no need to worry.
(or fear...anything at all)

but i do accept some folks just love their fear p0rn...


they watch it every single day...
...and seem to get joy in telling everyone that we are doomed due to the weather or killer invisible bugs or ice cubes melting or holographic space monsters..or whatever else is next up on the schedule.



but unfortunately reality will still be reality..
(ie there is nothing "there" to fear)
regardless of what their TV tells them to think

interesting..
.. how much did the sea level risen since 1620?
(it say "well documented" but a quickie google search was unsuccessful)


but i did find this...

Photographic evidence -
Unprecedented climate change caused level of Sydney Harbor to rise approximately 0.0 cm in past 140 years

People really need to stop buying all the propaganda nonsense disguised as science
