I’m not sure what they’re talking about. We had freeze warnings night-before-last here in NC. We decided to delay toting the indoor plants out to the deck for the summer...at least for a few days. And then the global warming-induced eclipse yesterday, scared the heck out of our dog. He didn’t know if it was breakfast time or supper.
It’s the overall earth temperature not a point North Carolina. But what was it before the records were kept? They never discuss that.
