Our world is within finite space, so we can surely take measurements accurately. Modelling the complexity is another issue which I would agree we don't have. We worked on those in the 70s when we focused on the root cause of what today we bicker over as Global warming. We had regulations being passed and consumer awareness about pollution and conservation. Today it has become all about the corporate profits and the argument no longer focuses on the root cause. Neither side of the global warming debate are being scientific, or logical and reasonable for that matter. They both have the same masters and neither really give a shit as long as they get a paycheck, which depends on their masters making lots of profits.
In other words, you don't seem to know the debate either and may have probably been played like a fiddle just like the majority of the public. More a question than accusation, which you don't have to answer. Just something for you to consider.
I'm not sure I understand your argument, all I hear from the scientists has to do with the root cause CO2, I don't really recall hearing anything from scientists about corporate profits. And the scientists generally work for universities or government labs, which carries some risk of government interference, but as a group scientists are one of the most aggressive about maintaining their independence.
What you claimed is that observation is what made science, and I claimed it was wrong. You get closer here, but not quite there yet. The whole definition of inductive reason includes the fact that some things can not be proven absolutely. It is a scientists job to question those theories and find weaknesses. If you claim a theory is proof and a person questioning is wrong, you are absolutely _not_ being scientific.
Not every question about a theory is bad, yet every question is treated as bad by people claiming to be intellectuals. Those same self proclaimed intellectuals close their ears to anything that threatens their belief in the theory, and loudly complain about those other guys ignoring 'science'. The hypocrisy is staggering if you care to look.
Nothing can be proven absolutely, even math proofs rely on a system of very basic assumptions we all just take to be obviously true, but we cannot prove formally. And all science outside of math relies on theories that are not proven. Even the theory that cigarettes cause cancer isn't proven and is likely wrong in some sense. Which part of the cigarettes cause how much cancer? The nicotine, carcinogen A, B, C, or D, simply the carbon smoke in the lungs? You tweak the cigarette formula to something like electronic cigarettes and it's suddenly unclear if these new cigarettes cause cancer.
And the reason 'self proclaimed intellectuals' get pissed off at certain questions is because those same question have been asked countless times and answered adequately each time, yet people keep asking them. And generally they ask it not because they want to know the answer, they ask it because they are trying to prove the scientist wrong.
Imagine a guy proclaims that if you went to the top of a cloud during a thunderstorm you'd see Zeus throwing thunderbolts down. So you put him in a plane and during a thunderstorm and fly above the clouds seeing the thunder and a distinct lack of Greek gods. So you land, he steps out of the plane, goes up to a crowd of his followers, and starts talking about how if you went to the top of a cloud during a thunderstorm you'd see Zeus throwing thunderbolts down.
You'd probably get pissed off too.
