Ógè oyi nke Oge Iron

Okpomọkụ ice nke Greenland na-akọwa na 18O isotope site na 6 ice cores (Vinther, B., et al., 2009)

Iron Age Cold Epoch (nkè a na-akpọkwa Iron Age climate pessimum ma ọ bụ Iron Age neoglaciation) bụ ógè ihu igwe oyi na-adịghị ahụkebe na mpaghara North Atlantic, Nké sitere na 900 BC ruo ihe dị ka 300 BC, ya nà oke oyi karịsịa na 450 BC n'ogé mgbasa nke Gris ógè ochie.
