Wasn't this reported months ago? And zones didn't suddenly shift just because the USDA said so. They've shifted over time because of climate change. The USDA just finally got around to catching up.
I used to be news director for an NPR member station, and even I think this is sloppy work.
This is a tool derived from that report which directly shows how the user's local environment has changed. Kind of trippy to see that the environment of my childhood is not the same as the environment I'm living in now. It's a good educational tool.
