San Francisco sea level rise by 2100 -- Science says +7 inches vs. U.S. National Public Radio claiming +7 to +10 feet !

US national public 
radio stations 
are leftist biased.

They will broadcast
any climate alarmist 
prediction that is 
bad news -- no 
questions asked.

San Francisco is 
much more vulnerable 
to an earthquake
than sea level rise.



In one recent 
NPR "story",
the listeners heard:
“Sea level 
in San Francisco 
is expected to rise 
by 7 to 10 feet 
by 2100”.
(Source: 
WAMC Northeast Public 
Radio out of Albany, NY,
in early August 2019.)  

A 7 to 10 foot rise
is almost double 
the UN's IPCC 
worst-case 
scenario, 
which was 
already 
nonsense.

Extrapolating the 
current trend
adds up to less
than +7 inches by 2100,
(calculations later)




US tide gauges in use 
for over 100 years reflect 
no acceleration of sea level
rise that could be blamed 
on CO2 levels 
(global warming).

Global sea level rise 
has been in the 6 to 9 
inches a century range,
not 7 to 10 feet.

San Francisco Bay 
has had a long term, 
steady sea level rise 
of about 6 inches 
a century.



Snay et al. (2007) 
examined 
the Vertical 
Land Movement
at Continuously 
Operating 
GPS Stations.

For San Francisco, 
the tide gauges show 
+2.13 mm/year in 
relative sea level rise.

But that 
"sea level rise" 
includes sinking of 
the land that
the tide gauges 
are mounted on --
sinking -0.83 mm/year.

If you subtract 
downward land 
movement (-0.83mm)
from the +2.13mm/year 
relative rise from the tide 
tide gauges, the actual 
(absolute) sea level rise
is only +1.3mm per year.


SAN  FRANCISCO
ABSOLUTE 
SEA LEVEL RISE:
at +1.3mm/year 
through 2100
would be 81 years 
x +1.3mm/year 
= +105.3mm total

105.3mm total,
at 25.4mm per inch, 
would be +4.14 inches.


+ SAN  FRANCISCO
LAND SINKING: 
at -0.83mm/year
through 2100
would be 81 years 
x -0.83mm/year 
= -67.2mm total

67.2mm total,
at 25.4mm per inch, 
would be -2.65 inches.


= SAN  FRANCISCO
RELATIVE SEA LEVEL RISE:
Absolute sea level rise
of +4.14 inches by 2100,
plus land sinking -2.65 inches,
by 2100, adds up 
to +6.79 inches 
of relative sea level rise
for San Francisco, 
assuming current 
trends continue.

Less than 7 inches !

Not 7 to 10 feet !



The Bottom Line: 
Leftists will say anything 
they want to say about
the future climate 
to scare people.

No other leftists will 
doubt their claims,
at least not in public.

The future climate
will be claimed to be 
completely different
than the past climate.

The predictions 
will be wrong.

But the people 
who made them
will be long gone.

NPR has broadcast
false news stories 
on the climate 
for decades !

Gullible fools believe 
the always scary 
climate predictions,
and vote for 
leftist politicians,
who then try to control
almost every aspect 
of people's lives.

I'm proud to say that
I'm not one of them !
