This NASA paper from the 2011 Earthquake in Japan shows that earth's axis can be changed, if earth were to get hit by a large CME at the start of solar cycle 25, when our magnetosphere has weakened even further then we could see a series of large quakes and core instability.
This would result in crustal displacements on a regional scale, along with damages from the CME.

The calculations also show the Japan quake should have shifted the position of Earth's figure axis (the axis about which Earth's mass is balanced) by about 17 centimeters (6.5 inches), towards 133 degrees east longitude. Earth's figure axis should not be confused with its north-south axis; they are offset by about 10 meters (about 33 feet). This shift in Earth's figure axis will cause Earth to wobble a bit differently as it rotates, but it will not cause a shift of Earth's axis in space—only external forces such as the gravitational attraction of the sun, moon and planets can do that.

Previous studies identified glacial rebound as the key contributor to long-term polar motion. And what is glacial rebound? During the last ice age, heavy glaciers depressed Earth's surface much like a mattress depresses when you sit on it. As that ice melts, or is removed, the land slowly rises back to its original position. In the new study, which relied heavily on a statistical analysis of such rebound, scientists figured out that glacial rebound is likely to be responsible for only about a third of the polar drift in the 20th century.
The authors argue that mantle convection makes up the final third. Mantle convection is responsible for the movement of tectonic plates on Earth's surface. It is basically the circulation of material in the mantle caused by heat from Earth's core. Ivins describes it as similar to a pot of soup placed on the stove. As the pot, or mantle, heats, the pieces of the soup begin to rise and fall, essentially forming a vertical circulation pattern -- just like the rocks moving through Earth's mantle

If our axis is shifting then the weather events we have already been experiencing are going to get worse.
I have stated many times that I believe these events will take place in slow motion to us, but in fast geological speeds. I believe the mantle itself is shifting and taking the crust along for the ride (a slow one).
