On the Paul James gardening show this last weekend
he was talking about gardening in the cities.  He
said that some cities have a growing zone as much
as one climate zone warmer.  This is because of
Urban Heat Island effect (UHI).  

I would be cautious about thinking of or planning
a garden depending on the supposed "global
warming" for every area of the United States or
the world. For example, there has been
significant crop loss for the wine industry this
spring in France and parts of California because
of cold snaps in the early spring.
