My guest this week is Valérie Trouet, a palaeoclimatologist, Professor of Dendrochronology at the University of Arizona and Scientific Director of the Belgian Climate Centre. In this episode, she discusses how: Studying tree rings can give insights into climate change over the past 2,000 yearsThere is evidence that climate change was a contributing factor to the fall of RomeScience needs the support of enabling government policy to turn insight into actionCommunicating scientific findings needs to generate consensus rather than divisionDendrochronology allows us to compare extreme climate events, such as wildfires, over timeKey links Valérie Trouet (LinkedIn) Laboratory for Tree-Ring Research (website) Tree Braille (poem) Thriving (book) Wayne Visser (website) Wayne Visser (LinkedIn)
