Hardiness Zone Changes

[dtotire]

Hardiness map from ArborDayFoundation.
Shows hardiness zone changes from 1990 to 2006. Increases show moderating low temperatures. For instance, northern Ohio changed form Zone 5 to Zone 6; northern Nebraska from Zone 4 to 5; most of North Carolina has been place in Zone 7; most states show increases.

4. Interesting

And horribly frightening at the same time. How much biodiversity are we losing because plants can no longer grow in the ranges where they've been for thousands ago? How many animals will die because the plants they've evolved to eat are no longer there?
