Over here, surveys show that plant and animal species have been noticeably
moving up the mountains and further north.  Indeed, on my slope of the
Sierra Nevada, it appears that when the current forests burn next, that they
will not come back, but rather be replaced by the current lower elevation
flora.

Growers of orchards and wine grapes are now planting varieties adapted for
what the climate is expected to be when the trees/vines come into
production.  E.g., the number of frost-free days in the famous Napa Valley
have decreased dramatically over the past several decades.

Agricultural pests are also moving north in Calif, which will likely
necessitate additional pesticide spraying, especially in areas where winter
chill used to kill them.
