You were doing so good the other day when you admitted "I don't know"
I've yet to see any climate effects on nutation.
Just because the atmosphere is involved, doesn't mean that it is climate forcing the nutation.
That's ridiculous. Are you going to claim next that climate causes every single tornado, hurricane, ice storm, drought, sand storm, hail storm, and any other meteorological phenomenon as well?
It's a random process. If I really had to put down a hypothesis, I would actually say that sea ice is more likely to be a climate effect that will impact the nutation, but it hasn't been shown.
That's the point. Just because you can cite some papers talking about the atmosphere, does not mean that climate change is causing the phenomenon. That hypothesis needs to be tested. Finding something only tangentially related is not proof that climate is impacting the wobbles of our planet's axis.
Maybe in blog science it's proof, but not in real science....
