I challenge you to look again at the original summary statement, and tell me you think it is an accurate, defensible description of the problem.
I say it is not. I say it is marketing-speak that really has no place whatsoever in a discussion forum targeted towards engineers. I say it is yet another low-quality statement that relies on hand-waving and alarmism.
Since I am an old fart and have been on this site for decades now, I am willing to put my name to my objections. I know in advance that I will be moderated down; moderation on /. has been broken by activists for many years now. But I have nothing to lose, and nothing to prove. I just want a competent discussion on the facts.
For example, I would like to know what caused the detected reduction. I suspect the study authors have some ideas, where are they? I would like to know where the measurements were taken. Were they in a field? In a city? Next to a factory? Next to a factory that recently shut down? I would like to have some intelligent discussion on how these results might be extrapolated to the world at large.
But we get none of this. We get more alarmist claptrap. I'm done with giving that a pass. I want some minimally competent science in these discussions. There are other forums where the PR types can ply their craft.
