One of the reasons why there's been a massive expansion of vineyards in Sussex -- and in other locations with marginal climates, where the best wines are produced -- is because of the warming climate. It's a long-term decision to plant vines. It takes three to four years before they yield fruit that is vinified. So there are plenty of predictions on the subject of wine vintages. It's a point where expertise is merging into economic activity. The insurance industry have been at the forefront of such activity -- in other words, they think you're spouting nonsense on this particular subject.
There is evidence of vineyards around the Roman villa at Chichester.
