There has to be a benefit of global warming and English wine is it. Go back 30 years and even the south coast of England was too far north to grow grapes, but Sussex and Kent now have the climate that Champagne had three decades ago, and can now produce great fizz. The lack of full ripeness when picking of the Champagne varietals in England is a benefit as the higher levels of acid make a great sparkling wine. This is, however, a problem for still wines.

You can't use the more well known grapes to make table wine in England as they won't get ripe. As a result, early harvesting wines, usually of German origin, are planted, but they too have a problem. They aren't that great. Occasionally a good wine pokes its head above the rest and is tasty, but mainly they are mediocre at best.  That isn't to say that they won't improve - as the world heats up they will get better, but just now, as a general rule, stick to the fizz!
