Are you saying you don’t trust climate science but you would trust them if they declared some other branch of science which has nothing to do with them as being unscientific? What does one thing have to do with the other?
Are you also saying medicine is not a science because doctors got it wrong about masks? Science isn’t about always being right, but about observation and experimentation to try to arrive at the truth and a deeper understanding. Can you name a single branch of science which has never got anything wrong ever?
Your last paragraph is particularly confusing. Is your entire post sarcastic? And if so, which group exactly are you criticising?
Some parts of science became political. The goal seems to convince a population, not determine what is true or not.
So if you extract one field which is extremely corrupt, with practices that would seem obvious to anyone who studied Stalin, which soils the ideas and principles of sciences, and another fields rejects the idea of denouncing the first field: that demonstrates that they are both politicized sciences. Covid science, climate science and social sciences all three ask you to “trust the science” and use authority to become right.
Meanwhile a researcher who is funded by private companies for technical advances, generally produces good science. They don’t usually need to jail their opponents.
This is such an ideology-laden bullshit leap that it pushes you into the "not even wrong" category.
