The most basic data points is rising average global temperatures and melting ice glaciers year on year across the last 40 years and the correlation between carbon and and temperature is predictable and consistent with prehistoric climates.
Any climate change model forecasting specific results will always be wrong as there is simply to much conflicting data points to accurately enter into a simulation.
However every single broad trend predicted has been 100% accurate.
I'm all for questioning Government but what benefit is there for Governments, worldwide, to create a climate change myth? Especially when many of the western world's Governments are backed by oil and/or mining corporations. How would you even get all the Governments across the world to buy into the scam?
I guess you are right about questioning what is presented as science on the internet but anyone of basic intelligence with any sort of schooling in the last 15 years should have enough science literacy to assess what is a legitimate scientific report.
Beyond questioning the validity of any one scientific paper, and possibly where their funding has come from, questioning scientist is a fools errand. Especially when your questioning a result with about 99% consensus within the scientific community
If you don't give a shit about human accelerated climate change that is one thing, but to deny its existence altogether is another.
