Ice core data is generally interpreted within the paradigm of "long ages" and chemical evolution.
It is bogus.
That's an interesting point.
I've always found it baffling that so few scientists seem able to recognize the circular reasoning behind much of the ice core data interpretation. I'm not even talking about the high-profile figures who have books to sell, institutions to protect, or agendas to promote. Their bias is almost expected.
What puzzles me more are the everyday researchers, the ones actually working with the data. They, it seems to me, should, in theory, be more objective. They often seem blind to the fact that their conclusions are preloaded into their assumptions. Instead of letting the evidence lead them, they let their worldview dictate how the evidence must be understood.
You would think that every once in a while, a young scientist, fresh out of school, without a reputation to defend and who is genuinely curious would raise a hand and say, “Hold on a second. Shouldn't we be letting the data guide our theories, not the other way around?” But that seems to never happen.
