Description
Yangyang Chen leads a team of eight reading ten thousand years of climate from a pillar of black soil in northeast China, in PLOS ONE in 2026. The Songnen Plain holds one of the world's three black soil belts, vital to national grain supply, yet how its rich layer formed is still debated. The team sliced a sediment profile and combined grain size fingerprinting, chemical weathering measures, and luminescence dating to build a dated history of the whole Holocene.
Five stages emerged. Dust piled up fast in the early Holocene, then a cooling spell arrived near the transition to the middle period, echoing a known global cold snap. The middle Holocene optimum, warm and humid, did the decisive work: weathering peaked and the black soil began in earnest. Late Holocene cold and dryness then slowed the process. The profile ties a farming treasure directly to an ancient climate window.
