England used to produce decent wines. But it's been too cool for the past few centuries, so people get their wine from France, Italy, Spain, California, or Australia instead. The idea that the current world is "hot" is ludicrous. We've known for a long time that the Medieval period was warmer than now and we've known for a long time that the Roman period was warmer than now.
We had a small ice age end in 1850, for goodness sake! The Global Warming thing is a complete scam.
