Fortunately we have only a couple of years to wait to see the accuracy of this model. I "believe" the sun is analogous to a pot of boiling water. When it is at its hottest if bubbles away. If you don't see bubbles it isn't as hot. I also "don't believe" that there is enough information to establish a causal relationship. Did the decrease in sunspots causing the Maunder Minimum precipitate the Mini Ice Age or is it possible the decrease in sunspots signal some other action which is also associated with temperature change. For instance one hypothesis is that the tidal forces of the inner planets affect the sun. If that is true the roughly 400 year variation of the earth's temperature is caused by the its action on the sun. Another consideration is the Earth's precession which has been attributed to the greening and desertifying the Sahara.

While I concede that the pollution that China is creating is disrupting the jet stream and causing really nasty weather in the US, I feel that there is other phenomena not explained by carbon emissions:

The magnetic pole started moving 100 years ago in a trajectory toward Siberia.

When the magnetic poles flip, Earth's protective magnetic field weakens, leaving its inhabitants at higher risk from the effects of space weather.
In the new study, researchers at the Australian National University analyzed the paleomagnetic record from 107,000 to 91,000 years ago by analyzing a stalagmite from a cave in southwestern China.
The team conducted magnetic analysis and radiometric dating on the meter-long sample, revealing the behaviour of the ancient magnetic field.
And, they found the magnetic field experienced a rapid shift over the span of about two centuries, decreasing in strength by about 90 percent when a field reversal occurred.

As can be seen by this illustration, the magnetic field strength has been waning for 3 hundred years.
