Changing of US Hardiness Zones

The oxalis is cheering us all up with it’s bright yellow flowers, the manzanitas are in bloom, the wild roses and black walnuts are leafing out. Is this normal? I don’t know, I just moved to Southern California from northern Minnesota a few months ago…..but according to The National Arbor Day Foundation things are changing. They recently completed an extensive updating of U.S. Hardiness Zones, based upon data from 5,000 National Climatic Data Center cooperative stations across the continental United States. Many of the hardiness zones have now officially changed.
