Note: The report seems to have been published online and not in a peer-reviewed scientific journal. The nonprofit that published it appears to have recruited third-party reviewers. As far as I can tell, there’s nothing obviously suspect about its funding. This is not my area of expertise.
The NAS - the National Academy of Sciences - formed in 1863 and is about as reputable an organization as you can find.
It’s the oldest of the groups in the umbrella organization that published this, the National Academies of Sciences, Engineering, and Medicine.
