A good press report on a good attribution study

For a change. Lots of English-language sources for this, and it's not clear which to link to. It's originally from Agence France-Presse. Here it is on Yahoo.

Rather less successful is this piece from the BBC on the same research, but it's still relatively good on the spectrum of this sort of reporting.

Because I'm trying to cover this ground myself in my book project, I'm trying to understand why I like some reports and so thoroughly dislike others.

For one obvious thing, though, the NPR report isn't actually reporting any science, just a bit of off-the-cuff speculation. But it's not that I am opposed to off-the-cuff speculation, as I intend to do some of my own.
