Summary: Changes in Agriculture using Viticulture as an example
Grapes are a very climate sensitive crop and vines have been cultivated for several thousand years. Over time many grape growing regions were established, whose specific climatic conditions matched the capacity of certain varieties to produce wines of distinctive character.
Through warm and cool periods of the past, climatic boundaries for successful grape growing became clear, which traditionally were located between the 30th and 50th degree latitude north and the 30th and 40th south or encompassing the 12° to 22°C isotherms for the growing season (April-October, October-April).
These boundaries will move north and south, respectively, in the future. Concomitantly, varietal suitability will be affected and a disruption of historically grown combinations (and identifications) of certain varieties with certain wine regions is likely.
The projected rise in temperature will also alter grape composition and thus wine styles produced and along with predicted changes in precipitation amount and temporal distribution will challenge grape growing and wine making in the future.
