TUCSON, AZ (Tucson News Now) - When it comes to gardening it's all about the 'zone'. Planting zones help gardeners determine what plants will thrive in their garden. But zones are changing thanks to climate change. According to Climate Central "as the planet warms under its thickening blanket of greenhouse gases, those zones are shifting northward."
The below images show how the planting zones changed from the 1971 to 2000 average to the 1981 to 2010 average. Click here for an animation of the change. This animation makes it easier to see how the blues and purples retreat northward as the other colors increase across parts of the nation.
While the changes is subtle at this scale, the impacts can be significant for the localized areas. The shifting planting zones mean plants normally grown in the garden and in nature will be driven out of some areas. Here in the mountainous west, it also means some plants are moving up in elevation to escape the heat.
