One of the most salient reasons for the scientific community to look elsewhere while climate science goes off the deep end with half truths is the way that science has evolved. I’m not talking about science in the labs of business, but “pure” science (though that modifier is perverse in the present day).
When someone investigated pure science years ago, it was because they were already successful in some other endeavor; science was essentially a hobby for the rich. Over the years though, as universities became more and more a part of the world, those who had no means became scientists, and investigated theories as professors and others and published papers. The problem with this is that those that were doing the research obtained grants to do the research. Now it has become a source of income and support. What does that do to corrupt “pure” science? It used to be that the scientist had no income based on what the scientist found.
Skip forward to today. On what does the vast majority of climate science depend, and thus the jobs of hundreds of climate scientists? At the very least, their livelihood depends on there being something that will encourage those that make grants to pay for the science. So what climate scientist would publish a paper that essentially says climate science is useless, because mankind as a whole has a minimal impact on climate and can do little to nothing about it? Only one who has no need for a job (which is now the exception rather than the rule).
The situation is worse than just a single scientist becoming more interested in making a living than the truth. When there are many scientists in the same boat, even if a scientist comes to his senses on a subject, he dare not challenge the established line. If he does he will likely be ridiculed and ostracized for his being out of step with the majority of the scientific community.
When science became a paid profession outside of the business world, it became of necessity corrupt. Those that are involved in the pursuit have a vested interest in seeing the outcome be worthy of publication and continued investment. Pure science is no longer pure, but is corrupted by the pursuit of money. That isn’t bad when a business is pursuing profit; at least when a business is pursuing profit, everyone knows to take what they say with a rather large grain of salt. The problem with science in academia is the hidden nature of the profit.
