The second story, which I wrote with colleague Dan Keating, will be published this morning. I’ll be back here to discuss what we found. And please feel free to comment on the story on the article page. This has been a lot of work and is the reason this blog has been quiescent for a couple of weeks. There’s a lot of data to go through, and we’re writing about a phenomenon for which there’s no simple explanation or singular cause. As always I’m so grateful that we have such smart readers out there who can help us make sense of these things. I’ll post a link when the story’s up.
Update: Here’s our story.
