Why it matters

The idea in context

As snow compresses into ice, it traps gases, dust and chemical clues. Antarctic ice cores can preserve climate records up to about 800,000 years, revealing past temperatures, greenhouse gases and volcanic eruptions from air sealed before human history.

Buz çekirdekleri, eski havanın küçücük kabarcıklarını saklar; bilim insanları böylece kaybolmuş dünyaların atmosferini okuyabilir.

Kar buza dönüşürken gazları, tozu ve kimyasal izleri hapseder. Antarktika buz çekirdekleri yaklaşık 800.000 yıllık iklim kaydı verebilir; yüz binlerce yıl öncesinin sıcaklıklarını, sera gazlarını ve volkanik patlamalarını gösterebilir.

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.
