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?
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.

Professor at the Physics Department of UTAD (University of Trás-os-Montes and Alto Douro)
Director of the Evenstad Center for Wine Education, professor and research climatologist at Linfield College
Winegrowing Partner and creator of the Vilafonté vineyards
Winery Assistant & Carbon Neutral Spokesperson at Keith Tulloch Wine
Alisdair Tulloch is a 5th generation grape grower and winemaker from the Hunter Valley, Australia. Having grown up in the wine industry, Alisdair has seen the effects of a changing climate in vineyards throughout his life, which inspired him to lead a charge of sustainability in his region. His family’s estate Keith Tulloch Wine achieved carbon neutrality in 2018, and was certified carbon neutral by the Australian government in March 2019 – just the second winery in Australia to achieve this certification. Besides his work in emissions reduction and sequestration, Alisdair is also a vocal advocate of climate change action and communicates the pressing issues facing the wine industry from this threat. Beyond climate, Alisdair is a hands-on practitioner of regenerative viticulture focusing on soil health and microbiology, as well as working passionately to preserve native biodiversity through multiple seeding and planting projects on the vineyard. Alisdair is currently working abroad for a family vineyard in Côte Rôtie France ahead of his return to Australia in early 2021.
