If the earth is moving upwards through 4d and 5d then its sacred geometry would have to change. 3d to 4d would remove the tip of the star tetrahedron from the North Pole and replace it with the top surface of the cube. Therefore changing the weather patterns. I'm probably talking rubbish here but I just thought I'd throw it into the mix.
You can find this info in David Wilcock's earlier books - Divine Cosmos, etc.
While I'm at it there is also the expanding earth theory to explain continental drift :

If the earth has been expanding for the last 200 million years, where does the extra mass come from. David Wilcock theorised that it came in via the poles as an energy that was then converted into mass. So if the polar energy vortex shifted ...
