Which would be part of the point that I am making.The rift is a divergent boundary, that compression is not part of the rift.
No they don't.I've seen this one already and it is ludicrous. They predict that Kamtchatka will close the arctic oceans while it has done exactly the opposite for eons.
Compare this:

What they're predicting, essentially, is that the atlantic will continue to open, that North America will rotate counter clockwise, and that Asia will rotate clockwise. If you look closely you will see that siberia and norway are still at approximately the same latitude, but they've moved east by 30°, and Alaska has moved south.
All of which is consistent with the motions implied by your age map.
