one side features scientists who have been developing the same story for nearly 40 years with ever-greater detail. they don't have paid PR professionals or troll farms, but they have a body of facts, which, when taken as a whole, are unimpeachable in their prescription for what needs to happen to prevent future global warming. perhaps you may say that an individual paper's finding is refuted. sure. we expect that to occur with no fewer than 5% of all papers within most fields. the other ~95%, while imperfect, will continue to support the same broad stroke conclusions as well as many of the most relevant supporting details.
in contrast to this standard of evidence, the other side features people who stand to lose money by allowing the body of facts to be acted upon. they have the money to pay PR professionals and make advertising campaigns, etc. they can pay their own scientists to do some fake research, but the cat is already so far out of the bag that it's career suicide to do so. in other words, their position is so hopelessly lost that they can't even find credible fall guys within the field of climate science to make up nonsense which supports their agenda. think about that for a minute.
in this situation, we should expect the scientists to continue doing what they've always done: developing their research to be ever-more comprehensive and detailed, thereby giving the other side a smaller and smaller space to live in. in reaction, the other side will try to muddy the waters as much as possible for as long as possible to give them time to pivot their money to somewhere where the scientists can't harm it by exposing facts. this is what they're doing with the bot campaigns: repeating talking points like you have to muddy the waters and prevent meaningful organized action which would harm their financial bottom line. it's appallingly clear.
this isn't really a situation where you talk about "both sides" having agenda and "needing to validate" everything. there's no contest anymore. everything has been validated. the agenda of one of the sides has been exposed as utterly devoid of merit, not to mention egregiously underhanded. the agenda of the scientists has been simply to be listened to all along, so that the common good can be serviced rather than discarded.
