Studies show that the impact of global warming could be devastating and that fundamental ecosystems will be modified. But what are the effects of climate change on grape growing and wine production?
According to this article, over the last 50 years, growing season temperatures have increased for most of the world's high quality wine regions by an average of 2°C, and by 2049, wine regions can expect an additional growing season temperature increase of 2.04°C.
Wine industry warned on climate change
Cool climate regions will benefit the most from growing season temperature increase as fruits will be able to ripen better and more varieties could be considered that cannot properly ripen there today. However, the warmest wine regions, which includes most of the vineyard areas in California, will suffer the most. In warm to hot regions, ripening is rarely an issue but retaining acidity and developing flavor can become increasingly difficult. These regions may have to consider other grape varieties that will produce better in a warmer climate. And some of the warmest regions, including Chianti, Rioja, Southern France, the Hunter Valley, parts of Chile and the Central Valley of California, have already experienced some tangible changes due to global warming.
Another negative effect of global warming is the fact that harvest time is moving to the warmest part of the year with reduced water availability and increased pest and disease burden. Moreover, rising temperatures come with an increased frequency of extreme weather events and a rising unpredictability of climates. Winegrowers, like all farmers, don't like unpredictable and unstable weather, which is often detrimental to vintage quality.

I hope that they change everything around...
Once the deep mystery of “climate change” has been solved
And “What’s green and causes CC?” is no longer a popular riddle,
The legacy of the era most likely will be:
“Never in recorded history have so many made so much over so little”.
(With apologies to the late, great Winston Churchill).
I used to be blithely about the issue, but after seeing some terrible changes, I thought to myself I need to do something too. I think to solve the global warming problem, it must be stormed at the national and international levels. But the total success is built upon the action of every individual, regardless of nationality, to conserve energy and focused on living in a greener, cleaner community. Thank you for this post. Happy Blog Action Day! :-) pm.
A good addition to this is a very good program I have been using, Food And Exercise Diary (WeightLossSoftware.Com). It is a food diary, medical diary, and exercise diary. Lots of functions.
