In Madagascar, ancient baobab trees are revealing a hidden climate archive stretching back more than 700 years. By analyzing carbon isotopes locked within tree rings, scientists have reconstructed rainfall patterns dating to the 1300s, uncovering cycles of extreme wet and dry periods. The study, published recently, reveals a dramatic shift from a peak wet period in the 14th century to a long-term drying trend that began in 1750 and continues today. Most significantly, the research debunks the colonial myth that Madagascar was a pristine forest destroyed solely by humans; instead, it shows that people and the landscape have adapted together to shifting droughts and fire patterns for centuries. Researchers say these insights could guide modern conservation and climate strategies, offering a powerful reminder that understanding the past is key to navigating an uncertain environmental future.
