The climate in North America is moving northwards. This image from ArborDay.org shows changes to the USDA ‘hardiness’ zones: 
The ‘Bagpuss’ stripes show that most of the USA has warmed sufficiently to grow plants a whole ‘class’ more ‘tender’ than 16 years ago. This means that people in the northern continental states will now be able to grow fruiting peach trees, where previously their winters were too harsh.
“The new 2006 arborday.org Hardiness Zone Map is consistent with the consensus of climate scientists that global warming is underway.”
