This week, we chat with Dr Kathryn Allen from the University of Tasmania, one of Australia’s few dendroclimatologists, about how she uses tree rings to reconstruct past climates and environmental change. Kathryn shares her unconventional pathway into science and how she built a career in climate research. Along the way, we explore how tree rings record rainfall, temperature and drought, what these natural archives can r...
