Winegrape diversity for climate adaptation
Our 2020 study in PNAS shows climate change harms wine (more heating = worse impacts). Harnessing nature (biodiversity) can help, but adaptation has limits. The faster we quit carbon pollution = more + better options. [Press release] [download paper]

Our 2019 Nature Climate Change study shows many wine regions grow just 12 varieties on up to 90% of their vineyard area- instead of exploring the thousands of varieties that may be better suited to a warming climate.

Our 2017 paper, led by Lizzie Wolkovich at Harvard, explores the potential for using natural diversity in winegrapes to adapt to a changing climate.

Understanding Winegrape Response to Climate Change
Grapevine diversity and climate change
In a collaboration established 2014 with Lizzie Wolkovich (Harvard), Dylan Burges, and Andy Walker (UC Davis), we are studying how over 100 varieties of grapevine planted at the University of California, Davis develop over the growing season in response to climate. This will help us understand the range of diversity available in grapevines to adapt to climate change. We are also studying the genetics underlying this diversity. Learn more in my blog post here and in the videos below. .

My collaborator Dylan Burge talks about our project (with PI Lizzie Wolkovich of Harvard) to understand the genetic basis of how winegrapes respond to the environment (phenology), and how important understanding this genetic diversity is for climate change adaptation, in this September 2014 Modern Farmer article and Cal Academy video.
