The grand total of increased temperatures is 0.6 degrees and no vine could even detect that.
Oh here we go. Say anything Longy. What do you know about vines and what they can detect. NOTHING!!!! Absolutely nothing but that doesnt stop you making up stuff to suite your argument. Here this is what the iconic winemaker Taylors' says about the effect climate warming is having on their grapes at

"Will Climate Change Affect the Way we Produce Wine? (Mon, 16 March 2015)
Vintage 2015 is in full swing across Australia. At Taylors, our winemakers hailed the beginning of vintage in the first week of February, when the grape parameters were all in balance – the sugars, acidity, tannins and flavour compounds. And this season’s fruit is once again a beautiful expression of our Clare Valley terroir, and of seasonal variations. The date of harvest changes every year, but we haven’t had a traditional autumn harvest on the estate since 2009. And we’re not alone.
Across Australia winters are warming, growing seasons are earlier, and vintages are coming forward. This is more than an observation. Viticulturist Professor Snow Barlow says research over the past 50 years shows coastal wine regions have warmed between 0.7 and one degree, and inland regions as much as two degrees. Vines are temperature-driven, so when the mercury rises, fruit ripening is accelerated and harvest dates are earlier.
The impact of global warming on grape growing
Professor Barlow has been at the forefront of research on grape growing and the impact of climate change since the Kyoto negotiations in the 1990s, but as Max Allen points out in The Future Makers: Australian Wines for the 21st Century, it wasn’t until 2007 that many winemakers heeded the science. The drought was taking hold, squeezing life out of sunburnt vines, and in turn shrivelling hopes for the wine industry’s long-term future, as climate experts predicted that by 2050 warmer growing regions would be out of production. The advice was to prepare for global warming, use less water, fewer chemicals, and plant more trees. And many did.
How the wine industry is adapting to rising temperatures
Some have moved to higher ground or further south to grow their cool climate Chardonnay, Riesling, Sauvignon Blanc and Pinot Noir. Others have planted vineyards east-to-west and manipulated the canopy to protect berries from the scorching afternoon sun. And we’re seen new technologies and innovations in grape growing and winemaking that are helping producers prepare for climate variations and extreme heat."
