If they cannot (or will not) produce the original source data - all the original source data collected; the computations (equations, constants, etc.) performed; reasoning behind including or excluding certain data; and the analysis of results... Then it is not much of a "scientific report" and probably isn't worth the paper it is published on. So-called scientists or researchers that refuse to publish their data and methodology are hiding something - shoddy work, plagiarism, or intentionally misleading work.
Really, we've seen this all before with the global warming nonsense. The left will lie, distort, cheat, steal, anything to advance their agenda. They have no morals, no conscious, and believe the ends justifies the means. That is not only wrong, their "end" is a terrible state of affairs including human oppression and misery.
It is not a new phenomenon - current lies relied on to increase government control:
ETS
Radon
Red-Light Cameras
etc.
