"I think the important analysis is a Northwestern twist of magnetic North, and hence some predictability in the warmth of certain zones, but most likely a cooling of others. It may not be stable, so for anyone in agriculture, then those farmers could be fooled by the change. An increase in warm temperatures may also mean a loss of moisture from evaporation. We could get hotter and dryer, in the USA especially as a result of the drought too." Quoting: Anonymous Coward 9662370
Apart from one 'slight' flaw. This isn't only happening in the USA!
Yes, the Northwestern twist is a WORLDWIDE phenomena. I never said otherwise. As an American, I can only comment on what I am seeing locally. However based upon the phenomena pattern, I think it's safe to assume that some regions will get cooler even colder as a result of the magnetic North displacement. No argument from me.
Re: hatch battener comments
Careful. An increase in hardiness doesn't mean an increase in moisture too. In fact there is a decrease. So while it may be warmer, it may be very dry this year based upon similar drought studies going on. See:

While your area may be protected, as well as the Midwest, much of the country has 70% of normal moisture in the soil. That can kill off nitrogen fixing bacteria colonies, and make the soil sterile. Heat doesn't necessarily translate to better crops.

Long term drought indicators. Couple that with a lengthening of the growing season. Not good. Hot and dry.
Minneapolis is experiencing 30-70 % of normal moisture. That's what the white zone means.
