Scientists have been publishing climate models since ~1970.

A good way to evaluate their skill is to compare what they expected to happen in the years after the model was published to observed climate changes.

It turns out most models were pretty spot-on:

NOAA have not updated the publicly available magnetic pole data [1] since 2020. The December 2023 State of the Geomagnetic Field report [2] does, however, contain some clues as to how things are progressing: "Since 2020, the north magnetic dip pole has moved at an average speed of 41 km/yr [~36.8° per century], and the south magnetic dip pole at 9 km/yr [~8.1° per century]. Neither underwent any noticeable change in direction. /// The South Atlantic Anomaly, where the geomagnetic field intensity is lowest, has continued to deepen (by about 25 nT at surface level) and move westward (its center moved by about 20 km at surface level) in the past year. /// In the SAA the intensity of the field is about one-third of that near the magnetic poles." By this account, the current geomagnetic excursion continues unabated.

Sun from May 8 to May 22.
Compiled video from footage from the SOHO heliospheric observatory.
Flares and coronary mass ejections are clearly visible.
The noise and debris on May 11 and 12 were precisely the particles entering the Earth that caused a magnetic storm.

[HaloCME @halocme]

A major eruption/CME earlier today (AR 13664), associated with an M8.8 flare and causing an S1 proton storm. Its spectrum was softer than the S2 storm from the 11 May CME (associated with an X5.8 flare). Only a weak coronal wave in this video may be related to a softer spectrum.

[HaloCME @halocme]

X8.2 flare from #AR12673 was impressive. Coronal wave went past both poles. Big proton event, likely GLE. EIS must've seen plasmoid ejection

[HaloCME @halocme]

A shock wave arrived at ~08:55 UT on 12 May 2024 amid the decline of the big solar storm. This new arrival may signal a glancing blow of the CME launched around 07 UT on 10 May (associated with an X4.0 flare), suggestive of no more direct encounters (AR 13664 being too west).

Playing with the Coriolis force.

A rotating merry-go-round is a helpful demonstration of the fictitious force that appears to act on objects moving within a rotating reference frame, such as the Earth.
