During the Obama administration, the EPA was allowed to make rules based on published studies in which the data and methods were kept secret by the authors or disclosed only to supporters.
Anyone who has worked in the sciences will tell you that if a thing cannot be repeated, it did not happen. But the EPA accepted result from authors who refused to release their data and algorithms so others could check their work, and allowed he use of “corrected data” without requiring the authors to disclose the rational for those corrections.
The result has been a mess, with papers coming to radically different results supposedly relying on the same data.
Expect to hear a great deal of anguished wailing, followed by retracted papers and a great deal of egg on the faces of journal publishers.
The EPA will finally follow the scientific method so if you are invested in wind or solar, make other plans.
