A difficulty in ice core dating is that gases can diffuse through firn, so the ice at a given depth may be substantially older than the gases trapped in it. 800,000-year ice-core records of atmospheric carbon dioxide (co 2) this page introduces antarctic ice-core records of carbon dioxide (co 2) that now extend back 800,000 years at dome c and.
