SUMMARY:
This Albert Parker
study's conclusion
is that a fingerprint
of man made effects
on sea level data,
has NOT been
found in records
from 30 long-term
Pacific Ocean
tide gauges.
This conclusions
is from a new paper
( Albert Parker, 2019 )
published in the journal
Ocean and Coastal
DETAILS:
The averaged
measurements
from these 30
tide gauge instruments
reveal a negative trend
in both the rate
of sea level rise
(-0.02 mm/yr)
and acceleration
(-0.00007 mm/yr2)
since the early
20th century.
Observations
of negative
sea level trends,
for the Earth’s largest
ocean basin, while
CO2 concentrations
rose from
about 300 ppm,
in 1900,
to 410 ppm today,
do not support
the claim that
man made
CO2 emissions
are a driver of
sea level changes.
Climate model projections
of meters of sea level rise
by 2100 are dubious
wild guesses.
“Japan has strong
quasi-20 and
quasi-60 years
low frequencies
sea level fluctuations.
... 1894/1906 to present,
there is no sea level
acceleration in the
5 long-term stations."
"In Japan tide gauges
are abundant,
recording the sea levels
since the end
of the 19th century."
“As the sea levels
have been oscillating,
but not accelerating,
in the long-term-trend
tide gauges of Japan
since the start
of the 20th century,
the same as all the other
long-term-trend
tide gauges
of the world,
it is increasingly
unacceptable to base
coastal management
on alarmist predictions
that are not supported
by measurements.”
“The Japan
Meteorological
Agency (2018)
has shown that
the relative rise
in sea level
on the coast
of Japan
has stabilized
since the
beginning of the
20th century
and has not
accelerated."
“At least 60 years of data
collected by
the same location
without any
perturbing event
are needed to compute
a reasonably accurate
sea level rate of rise
by linear fitting, and
almost double that length,
at least more
than 100 years,
are needed to compute
a reasonably accurate
sea level acceleration
by parabolic fitting."
“The relative
sea level rise
measured by
a tide gauge
has a sea and
a land component."
"The relative sea level
may rise, or fall,
not only because
the volume of the water
is increasing, or reducing."
"It may also rise, or fall,
because the tide gauge
instrument is sinking,
or uplifting."
