The problem with all of these comparions between ice cores and modern CO2 measurements is that we assume the CO2 trapped in the ice doesn’t migrate over time. If that were to happen, we would measure smoothened values over some period of time. This paper claims that this is exactly what happens: https://www.cambridge.org/core/journals/journal-of-glaciology/article/co2-diffusion-in-polar-ice-observations-from-naturally-formed-co2-spikes-in-the-siple-dome-antarctica-ice-core/8C8638D9EC90AEA53B90B3DE70E594C0
