Changes in Hardiness Zones
The latest issue of Progressive Farmer published some nice comparison maps of the 1990 and 2006 Hardiness Zones, which really laid it out and made it easy to see how drastic the change has been. I was searching online for copies of those maps to email to someone when I came across this great website of the Arbor Day Foundation, which shows the old map, the new map, and lets you go back and forth between the two to see what the differences are.
Although I knew we here in Atlanta had slid into Zone 8, I really had no idea that so many other entire state were also warming up so drastically. At Thanksgiving dinner in Ohio I was joking to my sister that she no longer needs to think about retiring to Georgia where it's warmer, because soon Ohio will be a nice warm retirement state itself. Looking at this map, I'm thinking maybe that could be true enough in another ten years.
Does this scare anybody else??
