(CNN)This week, a trillion-ton hunk of ice broke off Antarctica.
You probably know that. It was all over the Internet.
Among the details that have been repeated ad nauseam: The iceberg is nearly the size of Delaware, which prompted some fun musing on Twitter about where exactly Delaware is and how anyone is supposed to approximate the square footage of that US state. The ice, which has been named A68, represents more than 12% of the Larsen C ice shelf, a sliver on the Antarctic Peninsula. And most important: None of this has anything to do with man-made climate change.
The problem: That last detail -- the climate one -- is misleading at best.
At worst, it's wrong.
Some scientists think this has a lot to do with global warming.
I spent most of Thursday on the phone with scientists, talking to them about the huge iceberg off Antarctica and what it means. Here are my five takeaways.
