As a full-time climate activist, I have no illusions about the severity and impacts of global climate change. More than anyone, climate activists bear the heavy burden of this astonishingly vast problem and feel incredibly personally invested in doing everything in our power to halt and reverse global warming. So given my deep moral and professional interest in climate impacts and my fairly decent knowledge base on the subject, it takes a lot to thoroughly depress me.

But this is pretty depressing.
As a foodie and wine enthusiast (don’t worry, I go local and organic as much as I can), I was disheartened to hear that climate change could put a big squeeze on the premium wine industry in California. By 2040, the effects of rising temperatures could reduce the amount of land suitable for growing premium grapes by 50 percent. Gasp! No, don’t take our wine!
The effects of climate change on the Australian wine industry are already well-documented, receiving widespread news coverage and concern in one of the world’s most climate-affected countries. Warmer temperatures make grapes mature faster, affecting the quality of the end product. Experts claim that those with the most sophisticated palates may be able to taste the difference in vintages from the past few years. During the devastating drought that affected Australia from 2005 until recently, some grape yields were down as much as 40%. When you’re talking about a A$6 billion industry, that’s a problem.
Now researchers at Stanford University have recognized a similar pattern in California wines, and the California wine industry represents an even more impressive $18.5 billion chunk of the U.S. economy. The study, published in the peer-reviewed journal Environmental Research Letters last month, suggests that climate adaptation strategies could be applied to limit the projected losses. Wine growers could plant in new locations and use more heat tolerant varieties of grapes, alter the design of vineyards, and adjust winery processing procedures.
Just one more reason to keep fighting the good fight. Gotta have my vino!
