Our future?

Some climatology types have examined the effect on agriculture in the US—specifically premium wine grape areas—by a continued trajectory of increasing temperatures over the next century. The figure they used is 2–6°C. This is Figure 2-f, showing where the prime areas will shift to—that is, those areas lacking extremes of heat and cold. They make the point that wine is economically significant with 3.5 million tons of winegrapes out of approximately 6 million tons of grapes harvested each year. By converting them into wine, their value increases greatly, with concomitant deleterious effects if their production drops this much.

This is your world, and the projection is not pretty. Note how few premium grapes will come from California. In short:

… areas marginally suitable for winegrape production in the current climate were nearly eliminated and the area capable of consistently producing grapes required for the highest-quality and highest-priced wines declined by >50%.
