Instead of addressing this statement you decided to ask me questions.
I'd like you to address this statement.
Every theory we have defined in the history of humanity is wrong at the detail level so far.
So your point is mute.
Newton's theory of gravity is wrong... it appears to be right until you get close to light speed. It is a valid theory but in the detail it is wrong.
Einstein's theory of gravity and light is wrong. It appears to be right until you look at the very small.
Is Quantum mechanics correct.... no. It is a set of theories based on what is observed and they have to change it every time the theory doesn't match observation.
Are the laws of chemistry correct.... no... they do not take into account the small level of quantum events that may affect the perfect execution of a chemical reaction.
Until we have a unified theory of everything and how everything works at the micro and macro level... they will all remain wrong. Even when we have the perfect theory of everything we will still not be able to predict everything. The universe is not a billiard table.
Does that make these theory invalid. Of course not. They are totally valid at the appropriate scale.
Can we model in detail a chaotic system. NO. We can never do a full predictive and accurate model of a chaotic system. We can get a view at a summary level... but in detail... it can not. The universe has shown not to be deterministic at the very small but gives the illusion it is at the very large.
Now to you question/statement
Yet so far WE KNOW that the models are wrong and the THEORIES they are based on therefore must also be wrong
The models of the past did not take into account all the elements and parameters necessary for an accurate predictive model. They were high level based on our understanding of the earth and the limits of our algorithms, available input data, assumptions and limited processing power. Also some assumptions were wrong. (these are parameters of the models)
All of these things have improved. The current models due to the previous failure to predict accurately are continually reviewed, refined and with improved computing power more detailed simulations of elements of the chaos system that is the earth have emerged.
This will continue forever. (well until we wipe ourselves out anyway)
The broad thrust of the global warming is valid.
The long term effects of an ever increasing greenhouse gases is predictable to a degree.
I am not saying that we will end in a run away green house like Venus... the goldilocks zone we live in would probably allow it to auto correct over many years (may be 10s or 100s thousands) but the risk is real.
I do not believe we will let it get that far.
There is a real risk of hitting a threshold that has been hit before where methane and other higher impact GHGs will be released in a runaway scenario that once it starts we will not be able to stop. When it is all released.. .the planet will take a long time without humanity on the planet to recover.
Just because the current models proved to be wrong in it's short term predictions... doesn't mean the theory is to be thrown away. The details mechanics of the theory need to be refined. That is what is happening.
Just because there is no such thing as a straight line doesn't mean I cannot use straight lines in my explanation of things and use them in my models.
You guys really do not have an open minds.
Just because climate models can not predict the temperature and humidity outside my house at 11:00 am today does not mean the models are wrong. They cannot know the exact starting position and value of every atom, energy level, direction and quantum state (not that this matters because you cannot know it without affecting it) to feed the perfect model if there was one. If there was one it would need to be a computer the was a direct copy of the earth with the exact same starting state. Even then the model could then not predict the unpredictable that is the game of chance played at the very small scales.
Are weather models useful... yes. Do they help us take corrective or avoidance action...... yes. Are they wrong.... by your definition they are... so yes. Should we now disregard their predictions because they are not perfect and therefore wrong.... no fucking way. Do we state the theory of weather is wrong and therefore it should be discarded and ignored..... no. We improve on it... making it more accurate with each leap in computing power, improved algorithms, more data input, and corrections based on observation.
