Is Anthropogenic (Human-Caused) Global Warming/AGW Falsifiable?

Is Climate Science falsifiable?

Guest post by Hans Custers. Nederlandse versie hier. A very, ehhrmm… interesting piece on Variable Variability, Victor Venema’s blog: Interesting what the interesting Judith Curry finds…

Hans Custers is not a climate scientist. You’ll have trouble finding anyone but philosophers who confuse a hypothesis with a theory, your boy Popper does. He’s confused. Hypotheses are falsified, theories are not…..you’re confused too.

Hans Custers is not a climate scientist.

The author was Jos Hagelaars, an acclaimed and beloved climate change researcher/blogger who died last year.

Wrong.

So you can’t provide a working scientist/ institute that backs this made up shit. He’s just posting a philosophical view of poppers

 

[Dagosa]

Wrong.

It’s a myth that science illiterates fall for.
Science American is a science institute. It’s not made up shit. It’s no different than deniers, falling for made up shit.

The Idea That a Scientific Theory Can Be 'Falsified' Is a Myth

It’s time we abandoned the notion

Why so angry?

 

[Dagosa]

Wrong.

Take it a step further. The idea that science theories must either or can be proven or falsified is a myth.

Scientific Proof Is A Myth

We can demonstrate, suggest, and convince ourselves that a scientific truth is valid. But proof? That's an impossibility for science.

Wrong.

Nope……

I have no issue with Scientific American, but I'm not subscribing just to read an opinion piece that I suspect you're just reading wrong anyway.

In any case, you appear to be arguing semantics. In my experience, dictionaries best resolve such matters.

I agree completely that "proof" is best reserved for mathematics. But falsification is a whole different animal that you don't fully grock yet.

Falsification of science theories is the brain child of one person, Karl Popper, a philosopher and non scientist.
There is no science research facility or working scientist that mentions or practices it. None.
Maybe it is just semantics as every theory initially comes under the closest of scrutiny…….

A theoretical physicist weighs in..

What amazes me is Alarmists exist. Why do they keep telling us we are in danger from this salt you agree is in a virtually empty salt shaker. I like to use true numbers which is a bit more than 400 ppm and point out how small that amount is. It is not tenths or hundredths, it is part of a million parts. Tiny as that salt I mentioned before.

and according to highly correlated satellite and balloon data, the additional Co2 produced precisely NO WARMING in the atmosphere.

Popper is considered authoritative on this topic. From his Wikipedia article

According to Popper, a theory in the empirical sciences can never be proven, but it can be falsified, meaning that it can (and should) be scrutinised with decisive experiments.​

Note that qualification though: empirical sciences.

Theories are just as prone to falsification as hypotheses. There was once an almost universal "theory' that malaria was caused by "swamp gas miasmas".

An easy way to confirm that is watch the daily TV weather reports. Surely the alarmists do not believe that as the temperatures range a lot, that is caused by this magic gas?

The 'alarmists' do not believe that.

Thanks. No cause for alarm then about climate.

The regular record lows, the failure of "global warming" to shift temperature ranges higher = no ongoing climate change now.

A theory is a hypothesis that has survived attempts to falsify it and has successfully made predictions. That does not mean that new knowledge might not falsify it. Pappadave1 is correct. Many theories have been falsified.

Indubitably!
