Climate change, time for a change?

How do you know which way is East when you're at the North Pole?

Trick question.
Every direction is South

That's what I thought. I was confused by this:

...pushing the North Pole in an easterly direction.

But that's not the case. The Pole was moving towards the Hudson Bay, but the rotation South has moved to the East, the Pole itself is not moving East.

I don't think I'm going to lose any sleep (I lose enough already ) over the Independent's piece. It reads like a mish-mash of misunderstandings by someone looking for a story.

The axis moving about is nothing new and has several components.

The science is sound, but the consequences for life on Earth will be absolutely miniscule. The researchers studying this effect said that it's nothing to be concerned about.

The thing to be concerned about is that it's one more thing for the American religious right and all of Jeremy Clarkson's Twitter followers to claim is the "real" reason for "so-called" climate change (and yes, they do deny that it's happening and simultaneously claim that something is causing it).

I don't know if the double negative is intentional or not, but the researchers are saying that the melting is causing the tilting, not the other way round. The change is tiny. You aren't going to get global warming from that.

Earlier I posted that changes in weather could be caused by axial tilt. The response was 'wouldn't someone have noticed axial tilt?' I expect so. I could have mentioned the Inuits who have claimed the stars have shifted in relation to the landmarks they navigate by but no one would take that as a credible. Now it appears that people at NASA JPL are claiming axial tilt. Although the claim has been published by the Independent, it originated at NASA and no one is better positioned to observe it than they are.

The people at JPL are proposing that climate change has caused axial tilt. Whether they are right or wrong about the cause they have recognised axial tilt.

The full quote please. What I said was:

"And are you seriously saying that the Earth's axial tilt has changed enough to cause such massive changes over the last 30 years or so and nobody's noticed?!?!"

The Earth's axial tilt is constantly changing, but not every change is large enough to trigger global warming or cooling. If you're really interested, go and read about Milanković cyles.

Nobody is claiming that the very slight change in tilt is causing global warming - especially NASA.
