Yedoma is ice-rich Pleistocene permafrost built largely from wind-blown silt, preserving old organic carbon that becomes vulnerable to decay when the ground thaws.

Why it matters

The idea in context

During cold, dry Pleistocene conditions, dust, plant matter and great wedges of ground ice accumulated across Siberia and Alaska. Freezing slowed decomposition, locking carbon into sediment for tens of thousands of years. Thaw turns preservation into exposure: microbes regain access, landscapes slump, and an ancient store can re-enter the active carbon cycle.

Yedoma, büyük ölçüde rüzgârla taşınmış siltten oluşan, buz bakımından zengin Pleyistosen permafrostudur; zemin çözülünce ayrışmaya açık hale gelen eski organik karbonu korur.
Nefes alabilen donmuş arşiv

Soğuk ve kuru Pleyistosen koşullarında Sibirya ile Alaska'da toz, bitki maddesi ve büyük yer buzu kamaları birikti. Donma ayrışmayı yavaşlatarak karbonu on binlerce yıl tortuda kilitledi. Çözülme, korumayı açığa çıkmaya çevirir: mikroplar yeniden erişir, peyzaj çöker ve kadim depo etkin karbon döngüsüne dönebilir.

Speleothems such as stalagmites preserve layered chemical and isotopic records that can be dated to reconstruct past rainfall and environmental change.

Water filters through soil and rock, carrying dissolved minerals and a chemical trace of conditions above. Drop by drop, a stalagmite grows layers whose isotopes, trace elements and dates can reveal shifting rainfall and vegetation. The cave does not preserve weather like a photograph; it translates the surface into stone slowly enough for centuries to become measurable.

Peatlands cover little land but store enormous carbon.

Peat forms when waterlogged plants decay very slowly. Although peatlands occupy a small share of land, they store a huge amount of soil carbon. When drained or burned, that ancient carbon returns to the air, which is why wet peat can be as climate-critical as forest.
