It seems like Greenland is now accumulating gigatons of ice since bottoming out. Considering that have recently exited the Modern Warm Period, the graph you presented hitting the minimum of ice & the recent accumulation makes sense.

The weakening Geomagnetic Field strength also seems to drive the weakening jetstreams, resulting in increased polar & equatorial vortexes. Some areas are abnormally hot & some are abnormally cold.

Records are funny things, since they also depend on technology that has existed in a minuscule fraction of Earth's history to measure. Much of these advancements happened to have occurred following the Maunder Minimum, which featured "the year without a summer" into the Modern Warm Period. Now we have left the Modern Warm Period & have instability caused by the weakening Geomagnetic field, which occurs cyclically around every 12000 years.

It isn't the magnetic field that's causing weakening jetstreams, it's the rapid warming of the poles and the loss of the polar ice cap. https://www.nature.com/articles/srep45242
You cannot definitively rule out the magnetic field driving the jetstreams & even some of the temperature changes.

Space weather is being used to forecast Earth's weather.

Would space climate have a similar effect on Earth's climate? I'm not aware of any studies. Does the lack of studies mean the phenomenon simply does not exist or that we have not modeled the interactions between space climate variability & Earth's climate variability. We have only had satellites for less than 100 years.

The late Quartenary had a Geomagnetic excursion, with mass extinction of large megafauna, & weakened jetstreams causing equitorial/polar vortexes.

Other planet's atmospheric pressure dynamics is affected by magnetic field fluctuations.

There simply is not enough data to accurately & precisely model the dynamics of the climate. Nobody has created a control system that mimic's Earth's climate. All attempts have failed the test of time of a decade or two. The climate is very complicated, with a multitude of cycles, some lasting > 10,000 years. We have had modern measurement tech for about 50 years. Our sample size is too small to understand the dynamics of this system at this time. We will be surprised.

Even if there is a correlation, we don't have agreement of what the driving changes are. Does temperature drive the magnetic field? Does the magnetic field drive temperature? Are they mutually exclusive? Does temperature and/or magnetic field drive changes to the jetstreams? Does ionic activity coming from the Sun or cosmic sources affect the jetstreams?

We don't understand the Sun & the multitude of ways that it's variability affect's Earth. We don't understand the Solar System's position in space & the effects that that the local climate has. We are now observing how the galactic current sheet affects nearby stars. We have not yet fully modeled how interplanetary magnetic field dynamics (e.g. the 4 major gas giants clustering which is also occurring now into the near future) affect the climate as well.

Now back to CO2 driving the climate, I'll leave with an quote...
