Forests are under immense pressure from climate change, with hotter and more frequent droughts causing widespread tree mortality. Studies, like those in Biosphere 2, show how trees adapt by prioritizing water storage over photosynthesis, but their resilience is being tested. Dr. Christiane Werner is Professor of Ecosystem Physiology, investigating how plants and ecosystems respond to climate change from molecular to global scales. Her research spans from photosynthesis and water relations to ecosystem-atmosphere interactions, exploring how plants adapt to environmental stress and revealing the intricate connections between plant physiology and ecosystem functioning in our changing world. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
