Rapping about climate change - Why You Should Ignore "Expert" Predictions

The term "climate change"
is a generic term that means
little in real climate science.

Earth's climate 
is always changing,
locally and globally.

No one denies that.

As used by leftists, 
"climate change"
means much more.

Their "climate change"
most resembles a secular 
religion, based on beliefs, 
that apparently can't be 
falsified.

Beliefs based on "faith", 
like beliefs of conventional
religions.

As an atheist, since i was 
old enough to understand
the word, I accept that most
people like to be part of
a bigger group, such as a 
traditional religion, 
or the secular climate 
change "religion".

People seem to be 
very uncomfortable
with unanswered questions,
and not knowing what the
future will bring -- 
religions give them "answers"
stated with great confidence, 
and anyone who disagrees 
will be ignored, or character 
attacked.

Those "answers" all sound 
silly to me, but my "answer",
to those mysterious questions 
( " I don't know " )
sounds just as silly to them !




In real science, theories 
that can't be falsified 
are rejected 
as wild guesses.

If you predicted significant
global warming in the next
decade, as was common 
in the late 1990s, 
and the global average
temperature in 2018 
was about the same 
as in 1998, your theory
has been falsified by 
temperature observations.

But it seems that the belief 
in a coming climate catastrophe
remains, no matter what the 
temperature observations are.

Warm summer 
= climate change

Cold winter 
= climate change

No major hurricanes hit the US
48 states from 2005 to 2017,
for a record quiet period 
= climate change

A major hurricane hit in 2017
 = climate change




The claimed "solution" 
for EVERY imagined coming 
environmental catastrophe,
since DDT in the early 1960s,
has ALWAYS been the same: 
 A more powerful government,
issuing more regulations,
and higher taxes on energy.  

I say "imagined" catastrophe
because NO catastrophes
ever happen.

The predictions 
have been 
100% wrong.

But never mind analyses -
- the mainstream media
is too busy publishing new
scary predictions, to go back
and analyze the old scary,
always wrong, predictions
they published in the past.

"Climate Change" is wild guess,
always wrong, scary predictions
of a coming climate catastrophe,
that never shows up.

Predictions of climate doom
probably go back over one
thousand years.

Serious predictions, 
by a respected scientist, 
supported by some 
other respected
scientists, seemed to start
with oceanographer Roger 
Revelle, in 1957, who was 
Al Gore's idol.

To his credit, Revelle 
never became hysterical 
about global warming,
but he was always concerned
until his death in 1991.

Revelle, however, created the
"model" for getting government
science grants -- 
Using calm, very confident,
predictions of a coming crisis,
that needed further study

In the next few decades 
most scientists did not 
make wild guess predictions
of the climate far in the future.

But in the mid-1970s, 
after 35 years
of mild global cooling, 
while CO2 levels in the 
atmosphere rose significantly,
some scientists got attention
and fame by predicting another
ice age ( never mind that we 
were already in an ice age, because
Antarctica was covered with ice ! ).

The predictions ramped up 
a lot in the late 1980s, when 
the UN's IPCC was launched,
but they were for global
warming, not global cooling.

A very relevant question:
 How many decades 
should people wait 
until they stop believing
scary climate predictions,
and start celebrating
the actual mild, harmless
global warming, that consists
mainly of warmer, winter nights,
in high latitude ( cold ) areas,
where people love warming ?




I started reading 
climate science
articles and studies 
as a hobby, in 1997.

That day, probably 
in the first hour,
I stopped believing
the long-term climate 
forecasts that got 
me interested 
in the subject !

There was no evidence
anyone could predict
the global climate in 
the next year, much less
in one hundred years.

And the use of a single
statistic, the global average
temperature, never made 
sense to me !

No one actually lives in 
the average temperature.




The goal of studying climate
change should be to understand
what causes climate change.

That remains a mystery.

And that means climate predictions 
are meaningless climate astrology.

Or they are left wing politics
with an ulterior motive 
of scaring the general public,
so they will demand that their
government "do something".

Leftists love the government,
and when in power, they ALWAYS
want to do more, and they never
let a crisis "go to waste" as an
opportunity to seize more power
for the government. 

It doesn't matter whether the
crisis is real or imaginary, 
as long as people believe it.

The coming climate crisis 
has been an imaginary crisis
for over 60 years !

It's possible some people
will believe in it 
for their entire life !




Today there seems to be 
a contest for who can get 
published the most scary
climate change predictions
-- I call them "scary climate 
campfire stories".

A common theme: 
Claiming the future climate 
will be even worse 
than previously predicted.

Strangely, the new prediction 
is telling us something 
that no one ever notices: 
 The old prediction was wrong !

And if the prior forecasts failed,
why should we expect a better
forecast this time ?




The truth about predictions is that
"experts" are awful at predicting 
the future, yet psychology compels
people to take their predictions
seriously !

People want to know what 
will happen in the future.

With new predictions,
it takes time to find
out if they were right, 
or wrong.

But past predictions 
can be analyzed 
to see how far off 
they were.

Reading old predictions 
about the future climate 
may sound dull.

But they are 
good for a laugh
 -- that's why 
I include them 
on the blog.




The desire to know 
the future is universal.

People listen to "experts".

But the "experts" 
tend to be wrong,
from overconfidence,
even more than laymen !




American economist 
Irving Fisher predicted:
“Stock prices 
have reached 
what looks like 
a permanently 
high plateau.” 

That was October 17, 1929. 

The stock market 
crashed 
the next week !


Economist John 
Maynard Keynes 
predicted:
“There will be 
no serious consequences 
in London resulting from 
the Wall Street slump.”

Then Britain sank into 
a Great Depression too !




Herman Kahn, 
founder of the 
Hudson Institute, 
in his 1967 book
 "The Year 2000", 
predicted it was:
“very likely,” 
by the end 
of the century, 
nuclear explosives 
would be used 
for excavation 
and mining.

“Artificial moons” 
would be used 
to illuminate 
large areas at night, 
and there would be 
permanent 
undersea colonies. 

Kahn expected
one of the world’s 
fastest-growing 
economies would be
the Soviet Union !




A 1968 book called
"The Population Bomb", 
sold millions of copies.

Stanford University 
biologist Paul Ehrlich 
predicted: 
“The battle to feed 
all of humanity is over. 

In the 1970s, 
the world will 
undergo famines— 
hundreds of millions 
of people will starve 
to death in spite of 
any crash programs 
embarked upon now.” 

But there were 
no mass famines.

Between 1961 and 2000, 
the world’s population doubled, 
but food calories consumed 
per person increased 24%.

American waistlines 
significantly expanded. 

America now has 
an obesity epidemic !




Ravi Batra’s "The Great 
Depression of 1990"
spent 10 months on the 
The NewYork Times 
best-seller list
 -- the paperback 
stayed on the list 
for 19 months. 

The 1990 Recession was mild.




Economists’ predictions are specific.

Their accuracy can be checked. 

As a group, 
US economists 
have never predicted 
a recession !

Meaning that economists’ 
predictions are least accurate 
when they are most needed. 




In December 2007,
in BusinessWeek 
magazine, every one 
of 54 economists
predicted the U.S. 
economy wouldn’t 
“sink into 
a recession” 
in 2008. 

The consensus was that 2008 
would be a solid year. 





Scott Armstrong, an expert 
on forecasting at the Wharton
 School of the University 
of Pennsylvania, created the 
“seer-sucker” theory: 

“No matter 
how much 
evidence 
exists that 
seers do 
not exist, 
suckers 
will pay for 
the existence 
of seers.” 




Philip Tetlock, was a psychologist 
at the University of California’s 
Haas School of Business. 

In the 1980's, he began
interviewing respected 
experts -- 284 experts
—political scientists, 
economists, 
and journalists
— whose jobs 
involve commenting or 
giving advice on political 
or economic trends. 

All were guaranteed anonymity.

Over many years, 
Tetlock, and his team, 
collected 27,450 
predictions about 
the future.

Tetlock said the experts 
would have been beaten 
by “a dart-throwing 
chimpanzee.”

“There’s quite a range." 

"Some experts are so 
out of touch with reality, 
they’re borderline delusional. "

"Other experts are only 
slightly out of touch."

"And a few experts 
are surprisingly nuanced 
and well-calibrated.”

What made a big difference 
is how they think ?

Complex and cautious thinking 
trounced simple and confident. 

The bigger the media profile 
of an expert, the less accurate 
his or her predictions were.

Predictions made by applying 
mindless rules, such as 
“always predict no change,” 
beat the experts.

Another important conclusion,
that's often ignored:
 Tetlock only asked questions 
about the future for the study. 

Because he found that experts 
were good at answering questions 
about the present and the past.  




The world is 
too complicated 
to be predicted. 

But people want to 
eliminate uncertainty.

We see patterns, 
where there are none. 

We treat random results, 
as if they are meaningful. 

And we love 
simple narratives, 
over complexity
and uncertainty.

"Experts" that get noticed
by the mainstream media
sound very confident

We believe because 
we want to believe.

Skepticism does
not come easily.

But skepticism 
is absolutely 
mandatory 
for good science.

Skepticism is completely absent
from the climate change "religion".

Skeptics are verbally attacked.

That's why this blog exists.

I could not care less what 
any leftists say about me.

They are horrible people, 
who attack free speech
with ridicule and character 
attacks, try to micromanage
people's lives ... and destroy their
economy, with the "Green Ordeal"
( Green New Deal )
