Positive going prediction trend.
Latest output 01 Mar 2024 data to 2024.069165 (25 Jan 2024).

Indicial curve fit still the best fit and the century projection curve
y = 2.572365 + 0.092138*x^1.430674

y is global SLR in Aviso terms and x is year minus 2000, 6dp figures
retained for anyone else wishing to repeat/confirm these results.
To 2100 processing all the data each time ,from 2003.0 to avoid
post-Pinatubo global geodata hiatus ,775 datapoints, SLR of 69.528 cm.

Recent history of these processed Aviso 10 day outputs , after a very
long run of -going values , the 24 Dec 2022 one, the first regular 10
day whole-earth-orbits scan cycle Aviso output, started going positive
but then continued negative until July 2023 with El Nino kicking in.

From that curve for the last year 2023.0 to 2024.0,
annual global SLR of
5.13 mm and locally for South Hampshire UK , sinking
from post-glacial isostatic counter rebound by about 1.7mm/year, (minus
the 0.3mm/yr 'Peltier' global GIA included in the Aviso
reference figures) gives 6.53mm/year or more than 1/4 inch per year for
the Solent SLR, or more than half a millimetre a month local SLR.
Earlier results on the URL below. Being over-run by an increase in local
UK mean sea level of about 3cm/yr (yes cm ,not mm) in recent years,
maybe as much as 3.6cm for calendar year 2024. No academic reporting of
.. I suspect with slowing of AMOC and Greenland meltwater and Baltic
freshwater and so salinity change , less dense and consequential
increasing the sea height. The deep cold return path is not up to the
job and water is building up in the NE Atlantic.
A slowing of AMOC from the principle that reductions in the amount of
Atlantic bottom water reaching the ocean floor increases sea levels
because the warmer water that replaces it takes up more space.
Analysing the red/blue difference of the Newlyn residuals over time
https://ntslf.org/storm-surges/latest-surge-forecast?port=Newlyn&chrt=3
they should track together on average.
Similar separation for all other UK ports and in their recent archives,
when account is taken of the effects of local dregding etc on shallow
water ports.
It would be convenient to say there is a problem with the Exeter Met
Office/NTSLF big-data surge predictor of the blue or the non Z0 part of
NTSLF tidecurves underlying the red. But this UK MSL <>0.15m anomaly
over recent years is showing up with similar values in two other
independent monitoring processes, independent of NTSLF and independent
of each other. Unknown to me whether the same anomaly is showing up in
Scandinavia or Iceland, or France say. A possible alternative
explanation could be hydro-isostasy from the extra weight of sea water
in the last few decades , depressing the NE Atlantic basin. But how that
would affect the margin, ie like the UK, up or down is unknown to me ,
additional to post-glacial GIA, but difficult to see it amounting to
about 0.15m.
Or of course simple warming of N. Atlantic water to depth, increasing
sea level . Until the mechanism of this mean sea level rise is known,
its impossible to say whether the anomalous rise is limited, cyclic or
ongoing, currently my analysis of it shows it to be ongoing rising in
2023. Two researchers at the Proudman/Liverpool NOC are looking into
this anomaly.
Newlyn MSL anomaly latest determination rising 2.1 cm last year,
projected 3.9cm rise for calendar year 2023. Peak anomaly in April each
year , current prediction of 0.22m anomaly peak in May 2024 above global
SLR and local GIA.
