Extreme Weather Events: Response From The Vineyards

A changing climate leads to changes in the frequency, intensity, spatial extent, duration and timing of extreme weather and climate events (EWE). These are the words of the IPCC. Per se, these EWE do not prove the existence of global warming, but it is a given fact that climate change exaggerates them.

Reality, as we speak, is a reflection of this and of the current climate crisis: a few years ago, South Africa faced a period of severe water shortage in the Western Cape region. In 2017, the exact place where the Douro River is born, Picos de Urbíon, dried up. This year, in Germany, ice wine harvest failed for the first time due to a warm winter. A year ago, Australia was on fire, with an unrepairable and unprecedented loss for its ecosystems, let alone lives and businesses. As we speak, California, Oregon and Washington are being devastated by wildfires that preceded record heatwaves, followed by storms that ignited the fires. In Maryland, tornados were followed by hurricanes and then frost. Again, countless producers are still unsure about whether they will be able to save their harvest from smoke taint, and many have lost their vintage altogether.

Why? What are the causes? What are the impacts? How can we prepare our vineyards, our operation, ourselves, reduce the impacts and minimize the losses?

THE DEBATE

This Climate Talk will address these questions by gathering producers and scientists from different parts of the world that have experienced these EWE’s. They will share their knowledge, experience, different realities, and above all the ideas and practices implemented to tackle this reality. In a conversation starting with a scientific data approach, we will try to understand how can science help producers to predict, adapt and decide which are the best options available to deal with ewe, and how can they do this in a very practical manner.

GREGORY JONES

Director of the Evenstad Center for Wine Education, professor and research climatologist at Linfield College

Gregory V. Jones holds the Evenstad Chair in Wine Studies, and is a professor and research climatologist in the Department of Environmental Studies at Linfield College. He specializes in the study of climate structure and suitability for viticulture, and how climate variability and change influence grapevine growth, wine production and quality. He holds a BA and Ph.D. from the University of Virginia in Environmental Sciences with a concentration in the Atmospheric Sciences. His dissertation was on the climatology of viticulture in Bordeaux, France with a focus on the spatial differences in grapevine phenology, grape composition and yield, and the resulting wine quality. He conducts applied research for the grape and wine industry in Oregon and has given hundreds of international, national, and regional presentations on climate and wine-related research. He is the author of numerous book chapters, including being a contributing author to the 2008 Nobel Peace Prize winning Intergovernmental Panel on Climate Change Report, and other reports and articles on wine economics, grapevine phenology, site assessment methods for viticulture, climatological assessments of viticultural potential, and climate change. He was named the Oregon Wine Press’s 2009 Wine Person of the Year, named to Decanter Magazine’s 2009 Power List representing the top 50 most influential people in the world of wine, has been in the top 100 most influential people in the US wine industry in 2012, 2013, and 2018 (intowine.com), and named in the Top 50 Wine Industry Leaders in Wine Business Monthly in 2016, 2017, and 2018. Recently he was bestowed with the Honorary Confrade with the Rank of Infanção (Nobleman) from the Confraria do Vinho do Porto for his work with the Portuguese wine industry.
