Agriculture will shift .. which is different to fail.
Eg: Long established wine grapes in both France and mainland Australia have seen production falls already as local climates change in response to global parameters.
Brown Brothers (IIRC, an Australian wine label) has opened new vineyards further south (closer to the south pole) in Tasmania.
Another expected change is Cowboy Siberia; rodeo's, rodeo clowns, and vast cattle ranches on former tundra taking up the slack from US ranches as they bake and suffer from probable water issues.
I was not aware of Brown brothers new site, their site in Milwara is the definition of cozy. Next time I am in Tassie will have to check it out.
Due to the climate shifts, 'New Zealand wine' is becoming a swear word within the wine industry here as they significantly out do our quality.
shiraz grapes replacing pinot in Tasmania the past few years as well.
