These processes occur over thousands and even millions of years. Sending billions of dollars to Paris for "research" or trying to get people to stop using fossil fuels will do NOTHING to stop the next ice age. Though it is far more likely that the human race will go extinct out of stupidity before the next ice age comes the way we are going. If not, our distant descendants (hundreds of generations from now) living up north might have to consider migrating further south for a few thousand years while the ice sheets make their regular pilgrimage south.
Now let's talk about wine! When I was a kid, wine either came from France or California and it was expensive, unless you were Italian and you bought jug wine at the supermarket.
Now wine comes from all sorts of unlikely places like Oregon, Virginia or Long Island. Not to mention practically every civilized nation on earth. We are very rich in wine.
Texas has grown from the #10 producer to #6 over the past five years. Napa has become more of a real estate play, as real estate prices are approaching $3-5 million an acre.
That's why areas like Roseburg OR, and Idaho are seeing interest as wine producing regions. Roseburg's got a lot of farmland suitable for growing grapes. I don't know what a typical acre costs, a quick search threw out estimates between $15K to $50K per acre. Last time I was there, Roseburg had two dozen wineries and over $30 million had recently been invested new vineyards.
I lived along the Mosel for four years, it got plenty cold during the winter, and the low today in Traben-Trarbach was 41, typical for that time of year. OTOH, it was 45 degrees when I started my car this morning (Dallas), which means climate change is affecting us too.
Yes, these climate change worriers are freaks! Somehow people migrated throughout human history. Even taking hold in very cold climates, hot ones, too. We can handle this.
