There are variations in the MF over a scale of 100's of years that are not followed by global temperatures.
Actually most of the time the periods that not are parallel is up to 2 to 3000 years.
But in the long run this is "insignificant".
We are talking about 100.000 years period where the overall parallel curves is a fact.
The way to understand the graph is:

Basic.
The graph shows that global temperatures are changing fast, BUT temperature slow (“heavy”).
How this possible if the solar wind is should be the cause of both temperature and magnetic variation ?
Temperatures Variation
Comic rays are (off course) not delayed.
When the Suns (and the Earth’s) MF is weak we will have more clouds fast.
This mean temperature changing will happens almost immediately
(There can be relative small delays, globally either to cool or heat the Earth).
But the effect is relative fast. This is what we see in the graph.
Magnetic Variation
The magnetic variation can be delayed in hundreds of years (up to 2 to 3000 years).
Simply because the moving MNP is completely it’s own.
The motion of MNP is completely "accidental".
For example the last 2 to 3000 years the MF of the Earth have been decreasing,
BUT the Suns MF has been strong.
If this not would have been the case, maybe many countries would't have existed (been over flooded).
This statement is not something I “invent” see for you self that this seesm to be the rhyme of nature that repeat it self.
The last interglacial period was 3 degree warmer.

This suggests that the MF of the Earth in that period was much stronger.
It also could suggest that there were stronger cosmic rays, or uncertainty measurement result.
Several factors play a role, and yes it immediately can (seen from a limit perspective) look like this staement is contradictionary.
We know that there is a coincidence between the Earth’s heavy and slow magnetic field variation, - and the much faster temperature variation.
We can see that on the BIG scale these are “parallel” .
This is common knowledge that shall NOT be under estimated.
Furthermore we know there is a lot more problem to get serveral phenomena's to adapt to the Geo Dynamo speculation.
- The facts that in period the Earth magnetic field is so weak that it remind of the magnetic field of Mars, that doesn’t have any inner dynamo, but only a weak and chaotic ferro magnetic crust field. - In these periods not the worlds must stupid cow can see any need for a inner dynamo.
- The South Atlantic Anomaly can’t be explained by a inner dynamo muddle, but a ferro magnetic crust theory doesn’t have that problem.
- The many of the crust anomalies can’t be explain by the geo speculation, - but a ferro magnetic field combined with thermal heat flow doesn’t have that problem.
- The coincidence between thermal heat and magnetic anomalies can not be explained by a inner dynamo speculation, but a ferro magnetic crust field theory doesn’t have that problem.
Therefore we should be much more carefully to brainwash
everyone with the Geo Dynamo religion.
I mean it is always good that at least one is left behind ready to step the brake.
Then why do you agree on that? What has the origin of the magnetic field to do with it's putative effect on the climate? Why exactly is a ferromagnetic field able to affect the climate, but not a geodynamic one?
We know that Sunstorm affect and periodically
increases the MF of the Earth.
BUT the Earth will soon after a Sun storm loose these contributions.
Notice we have only measured that in a period of about 30 years.
In this period MNP have moved in a
bad magnetic conductive area.
The fast motion in a bad conductive areas rearranges the MF and make the MF chaotic.
The faster MNP moves and the stronger MNP is, the more it will interrupt the MF in its “wake”, and hence the MF of the Earth will fast lose magnetic force.
So soon MNP (in these years) arrives and stay inside a thermal heated area in the Artic Ocean, - MNP (the MF of the Earth) will loose its ability to created magnetic chaos. Hence the MF as well as the contribution from the Sun will no longer be lost.
