COVID-19: The evolution in Luxembourg
(Day
0 = 29-Feb-20)
As we are nearing hopefully the end of
new infections & new deaths, these graphs will be
updated only every second day (uneven day in May),
together with the animations!
25-May-20, evening:
Totals are for 86 days.
the Gompertz fit (green
curve) has an asymptote that is statistically
significant. The end of new infections will
probably be around the 20th May.
Note that the maximum number of deaths will be
reached possibly only a few days later than that of the total
infected, possibly around the 1th June.
The uncertainty range for the expected maximum death
number is narrowing fast; compare with the
situation of the 17th April (below).
Look
here for an animated GIF's (update every 2nd day):
At day 84 (23-May-20) there is a visible
mismatch between the Gompertz curve and the observed
Totals!
The number of death's does not follow
the Gompertz very nicely, even if R2>0.99, as shown
by the plot at the left.
One reason is that the reported number of deaths
varies strongly per day...
All Luxbg. Covid-19 numbers also on
Wikipedia.

Luxembourg people who have been tested for COVID-19
are asked to voluntary participate in the making of

Italy: COVID_19 and the Gompertz curve
(Day 0 = 25-Feb-20)
The updates will be done for Italy only all 10 days
approx. (sorry, I am too busy...)!
The Gompertz curve is a very good
fit for an ongoing pandemic (see Willis Eschenbach's
post on South Korea data
here and also follow the comments). I made a
quick check for the expected death toll and total
number of infected people for Italy, where the
former is the most important parameter. I fitted the
Gompertz curve parameters to the Italian data
published
here. The death toll peaks at about 12000,
to be compared to the approx. 17000 per year due to
common influenza (link).
The x-axis represents the days, with day 0 being
the 25th February 2020.
I will update this curve if more data become
available.Watch also this very
interesting
simulation in the Washington Post, which
shows the effect of "social distancing".
23-May: (88 days,
UPDATE!) The next
2 plots show the situation the near perfect fit with the Gompertz
function. The expected plateau will be reached after
day 100, i.e. practically at mid-June 2020
! So this will happen about 1 month later than in
Luxembourg. The plateau for the death
number is expected for a couple of weeks later
(possibly end of June). Note
that the uncertainty ranges both for totals and
death number has become very narrow. So when things
continue as predicted, sanitary and political
decisions for the near future are easy to make.

Cooling
ICE SAINTS

The Frost Saints or Ice Saints days ("Eisheiligentage")
are cooling since 1998 at meteoLCD, and still longer
in Germany. Did you hear about that in the media?

Research done at a geothermal
power station in Iceland has shown that gazeous CO2
dissolved in water which is injected into
underground basalt rocks mineralizes in just 2
years, and such will be safely stored away
indefinitely without any risk of leakage as they may
exist in traditional CCS (Carbon Capture and
Storage) systems..

The ongoing solar minimum continues to increase
the cosmic radiation at the altitudes of
transatlantic flights (20000 - 40000 feet). The
hourly dose may reach about 3800nSv, to be compared
to the 80nSv common at ground level (look
at our radioactive measurements!)

Read this
interesting article on HALEU (high-assay,
low enriched) nuclear fuel from disused ERBII
reactor and its planned use in the Oklo Aurora
micro-reactor at INL (Idaho National Laboratory).
HALEU is seen by many as the fuel for small reactors
and as a tool to recup energy from spent nuclear
fuel.
The Oklo Aurora reactor is a reactor
running on metallic fuel, without any liquid
circuits. |

The German philosoph
Gunnar KAISER
asks 12 very logical, but easy to understand
questions regarding climate and its variation; he
asks these questions to the famous TV physics
professor Harald Lesch. Watch the
YouTube video
(German spoken, about 17 minutes) and just try to
follow the logic!

Look at these graphs which show a similar 60-year
sinus-pattern for the velocity of warming and the
change in ocean heat content. Note also that the
velocity of warming seems to be uncorrelated to the
yearly CO2 emissions (here gigaton C/year, right
axis, red plot).

Clive BEST has a good article on the
baseline
problem of temperature series, and why the
choice of the baseline period is influencing the
concordance (or discordance) between models and
observational data:
"It
is the model projections which change dramatically
when using different baselines. One should always
bear this in mind whenever an ensemble of models
seem to perfectly match the data well."

A look at the Shape of Temperature Change over Time.
Interesting blog comment at WUWT by Mark Fife concluding
"In every 10-year average, 99.7% of the
stations fall within 2.25° and -1.75° of their 1920 –
2011 average".

change in 12 minutes". Peek also into this
animated
video by Dr. Roy Spencer.
Bill Gates, who said poor countries
“desperately need cheap sources of energy now to fuel
economic growth that lifts families out of poverty. They
can’t afford today’s expensive clean energy solutions and
we can’t expect them to wait for the technology to get
cheaper.” - See more at:

James
Lovelock: "They all talk, they pass laws,
they do things, as if they knew what was
happening. I don’t think anybody really knows
what’s happening. They just guess. And a whole
group of them meet together and encourage each
other’s guesses." (link)
97. Words
of the great physicist Freeman Dyson:
"Unfortunately the global
warming hysteria, as I see it, is driven by
politics more than by science. If it happens
that I am wrong and the climate experts are
right, it is still true that the remedies
are far worse than the disease that they
claim to cure."
98. Words
by the great French philosopher Pascal Bruckner:
"All the foolishness of
Bolshevism, Maoism, and Trotskyism are
somehow reformulated exponentially in the
name of saving the planet." (comments

R. Lindzen: "Future generations will wonder
in bemused amazement that the early 21st
century's developed world went into hysterical
panic over a globally averaged temperature
increase of a few tenths of a degree and, on
the basis of gross exaggerations of highly
uncertain computer projections combined into
implausible chains of inference, proceeded to
contemplate a roll-back of the industrial age"

"Le
doute est le commen-cement de la science ;
qui ne doute de rien n'examine rien ; qui
n'examine rien ne découvre rien ; qui ne
découvre rien est aveugle et demeure
aveugle".

Some say the world will end in
fire,
Some say in ice.
From what I've tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.
Fire and Ice, R. Frost, 1920
