The Amazon basin contains the world’s largest rain forest, famous for its rich biodiversity and importance in the world’s oxygen and carbon cycles. It also has an outsized influence on water cycles in South America and beyond. Understanding how climate change is affecting Amazon hydrology is thus a key priority for climate researchers. However, modern measurements of the region’s annual rainfall don’t provide the historical context needed to explain a recent uptick in wet season precipitation.
