Martin, I believe this is from an American environmental news website, and the NPR that the report is attributed to is the US National Public Radio, the equivalent of the BBC here, so they're quoting from an in-depth BBC-style (presumably fairly impartial) radio news report.
Both this article and the radio report they quote from are both pieces of journalism aimed at highlighting the emerging problems and bringing them to public attention in a form that the public can easily understand. It's not a scientific paper. And to call it dodgy and put out by people with an axe to grind is, I think, a bit much given the source. You make it sound like uninformed ravings from a blogger, when it's actually a serious attempt to address an important issue by, presumably, fairly responsible journalists working for the US National Public Radio.
