Produce a paper that casts doubt on climate change and you'll be labeled as an oil company's stooge.
Wrong, wrong, wrong.
Nobody HAS produced a scientific paper (or very few anyway) because you need proper evidence and to be able to cite scientifically sound, independent studies to do so.
To publish a paper that anyone will read at ALL, requires that the work behind the study can be examined and ripped-apart potentially, and attempts made to replicate it, the maths all checked, the sources checked, sample-sizes checked.... everything checked. Publicly.
That's EXACTLY what happens to a paper when it is published in order to BE scientific. And even after that, the conclusions will not be TRUSTED until others have confirmed it.
People who fear that process, avoid it. ONLY people who fear that process, avoid it. And avoiding it is what studies done by oil-companies etc, have done.
People who want to find the truth, welcome it even if it shows their own conclusions to be wrong. And that means making all those details fully available in the paper. A study paid-for by WHOEVER, is utterly irrelevant to any conclusion the scientific community might reach a consensus upon, if those details are kept hidden.
It is FAR from a perfect system, because some papers are not sufficiently interesting for anyone to take much time over it. If enough time passes without anyone debunking its contents then someone else further down the line who doesn't check their citations properly may assume that it is accepted science when in fact it just got ignored.
That's where it fails sometimes; it can make advancement slower and more conservative than it needs to be, though not seriously wrong in any major fashion and always advancing in roughly the right direction until the truth is inevitably reached.
With one exception: Whatever the unscientific media decides to cherry-pick and turn into a headline without any research. Which of course, is what people who do pseudo-science (ie poorly conducted research that is designed to reach a desired conclusion, not the other way round) want.
That's why people who understand science get science from scientists, not from journalists whose priority is shouting loudly about something or nothing.
So where does that leave us with regard to climate change?
It leaves us with the KNOWLEDGE that the climate is changing and that it is going to be horrendous for our species and for many others upon some of which we depend, if something is not done by those who have the power to do it.
