There is also evidence that the poles are moving even faster and the magnetic field of he Earth is weakening much quicker than previously thought. And luckily we have some open minded scientists who are actually taking a look at this and concerned that it may also be affecting the extremes in weather patterns and may have even greater effect when/if the magnetic field weakens more. However, it must be stated that we need a lot more data to fully understand these patterns.
Poles are moving fast
Weakening magnetic field

Is it possibly connected to climate changes?

It is thought that the Earth used to have regular pole shifts for about 80 million years, in about 200-300.000 year intervals. But according to NASA it hasn't had one in 780.000 years, so some say it's long due. However, these scientists believe the Earth had a magnetic pole shift and a weakening of the magnetic shield down to 5% of 2012 field strength and they believe the process possibly threw us into an ice age.

What is remarkable is the speed of the reversal: "The field geometry of reversed polarity, with field lines pointing into the opposite direction when compared to today's configuration, lasted for only about 440 years, and it was associated with a field strength that was only one quarter of today's field," explains Norbert Nowaczyk. "The actual polarity changes lasted only 250 years. In terms of geological time scales, that is very fast." During this period, the field was even weaker, with only 5% of today's field strength. As a consequence, Earth nearly completely lost its protection shield against hard cosmic rays, leading to a significantly increased radiation exposure.
Whether the pole shift 41.000 yrs ago was a full shift or partial shift, they think they know that pole shifts or partial pole shifts can happen within a human life, it can take hundreds of years or even up a thousand or a couple of thousands of years. But it seems like not enough scientists know enough about the totality of the effects it can have since we lack data. But to assume that a very weak magnetic shield that is not in its full capacity to protect the Earth from solar and cosmic rays will not affect life on Earth and even climate is imo highly unintelligent, I would go as far as calling it stupidity.
