Gardeners have been noticing changes in the climate for years.  The growing season is longer and plants that used to be considered too tender can now survive in more northern regions.  In fact, the hardiness zones have shifted northward.  The Arbor Day Foundation created new hardiness zone maps, in 2006, to reflect this change.  The USDA released new maps in 2012.
