I challenge you to present your best single source of evidence to support your argument.
After you have presented that, you are not allowed to come back with more evidence. It was what you consider the best and most rock solid. Something you hang your credibility.
Usually the opinion like yours is just 'general attitude' and some individual instances of scientific fraud that is not evidence of anything being consistently biased.
I'm not a climate change denier in any way but, did any of the predictions (the ones with dates and numbers) of Al Gore in "An inconvenient truth" become reality? There has been a non trivial amount of hyperbole going on in this subject.
Again, I'm making the claim that it's been exaggerated/politicized (to what degree is hard to tell, due to so many bad incentives). I can absolutely cite many cases of missed models, corruption[0] (btw if you disagree on this one, there are many more cases like this) and fear-mongering going from the IPCC to politicians to university research that's all been shown to be anywhere from misleading to outright fudge - but - it's not some single thing. So your desire for "one piece of evidence" is not the right way to discuss this. A case has to be made.
If you want a case, here's one of the books I mentioned [1]. It's not entirely perfect, but an example of how you can absolutely make a very valid, science-based attempt at a world-view that refutes many of the central tenets of modern climate change ideology.
Don't confuse me: carbon emissions are an important problem, one we need to solve. But you have decades of people like Gore to AOC to celebrities to even legit scientists, all on the left, who make claims like "we're X years from Y major catastrophe", and they end up wrong. Then you have corruption scandals, inaccurate models and stories of suppression of non-narrative-fitting data, and the democrats beating it over everyones heads constantly.
All I'm saying is this: it's very understandable that the Average Josephine on the right is skeptical. Any claim that says "the righties are dumb / purposefully ignorant" is missing an important piece of socio-cultural dynamics and rational game theory - having a distrust of an institution thats been intensely politicized is... fairly rational.
