*Over some years I was hovering over the developments of the ESA SWARM mission and probing random magnetometers from the Russian-Ukrainian observatories as a private researcher and a non-scientist. I'm trained in social sciences, so I have no background or methodology in science as a discrete discipline Did anyone else make a connection between drifting magnetic Poles, climate change, tropical relocations and such? Did anyone explore the Sun-Earth connectivity in relation to such changes? I leave some figments of research behind. I would be more than happy if I would be provided with an informed answer, thank you *

Abstract—Recent studies have shown that, in addition to the role of solar variability, past climate changes may have been connected with variations in the Earth’s magnetic field elements at various timescales. An analysis of variations in geomagnetic field elements, such as field intensity, reversals, and excursions, allowed us to establish a link between climate changes at various timescales over the last millennia. Of particular interest are sharp changes in the geomagnetic field intensity and short reversals of the magnetic poles (excursions). The beginning and termination of the examined geomagnetic excursions can be attributed to periods of climate change. In this study, we analyzed the possible link between short-term geomagnetic variability (jerks) and climate change, as well as the accelerated drift of the north magnetic pole and surface temperature variations. The results do not rule out the possibility that geomagnetic field variations which modulate the cosmic ray flux could have played a major role in climate change in addition to previously induced by solar radiation.

Gyre-driven decay of the Earth’s magnetic dipole

Christopher C. Finlay1, Julien Aubert2 & Nicolas Gillet3

Direct observations indicate that the magnitude of the Earth’s magnetic axial dipole has decreased over the past 175 years; it is now 9% weaker than it was in 1840. Here we show how the rate of dipole decay may be controlled by a planetary-scale gyre in the liquid metal outer core. The gyre’s meridional limbs on average transport normal polarity magnetic flux equatorward and reverse polarity flux poleward. Asymmetry in the geomagnetic field, due to the South Atlantic Anomaly, is essential to the proposed mechanism. We find that meridional flux advection accounts for the majority of the dipole decay since 1840, especially during times of rapid decline, with magnetic diffusion making an almost steady contribution generally of smaller magnitude. Based on the morphology of the present field, and the persistent nature of the gyre, the current episode of dipole decay looks set to continue, at least for the next few decades

The precession peaks found in the 3180 record from core MD900963 are in excellent agreement with climatic oscillations predicted by the astronomical theory of climate. Our ~180 record therefore permits the development of an accurate astronomical time-scale. Based on our age model, the BrunhesMatuyama reversal is dated at 775 + 10 ka, in good agreement with the age estimate of 780 ka obtained by Shackleton et al. 3 and recent radiochronological A r / A r datings on lavas [9-11].

  • $\begingroup$ Quite well formulated question though. Might actually not be duplicate as OP specifically asked what are the arguments for this connection unlike in the existing 'is there a connection' question. Might be that there are arguments, but they are unproven. $\endgroup$

  • $\begingroup$ @Communisty The original covers both "for" and "against" -- indeed, every answer to that question includes a "for" element. As to the formulation, I prefer the concise original. Three of the four papers quoted in the new question have nothing to do with geomagnetism-climate relationships, so they just distract from the question. $\endgroup$

  • $\begingroup$ I can't see that you would've listed any arguments supporting a connection in your original answer. $\endgroup$

  • $\begingroup$ @Communisty Please see final paragraph of my answer (“Of course, it's likely that geomagnetic field strength has some influence… sure enough, it turns out that Vieira and da Silva (2006) have found such an effect.”). $\endgroup$
