I was an invited speaker at a wine conference near Paris a few years back, the first speaker talked about the impact of CC on theh wine industry. It was in French, but the upshot was "dire and soon". Wine grapes require specific terroir to make very good wine, and you can't move most wine regions a bit north to get a cooler climate because the soil changes, or it's a river or mountain or whatever. (Napa is cooler in the south anyway). So, CC SHOULD harm the wine industry "soon", but hasn't. Yet.
It's a canary in the mine of coal in effect. Part of this is the changes in T reported to date are actually pretty modest, well within normal variation year over year, and growers can manage, but IF we double that, I think many would be in trouble. But I also think they would be 50 years from now, not 2030.
The T change is so slow we wouldn't notice it vicariously without instrumentation.
