The potential effects of a Maunder Minimum on our present climate trend by 2100 would be a decrease in global temperature of 0.1°C . With all uncertainties taken into account, the estimated maximum decrease in global temperature is 0.3°C. In other words it would be totaly negligible. Looks like you deniers need another straw to grasp, your flogging a dead horse on this one

As far as I can determine, the solar magnetic reversals could possibly trigger an Earth magnetic reversal, but I'm guessing intensity would be a factor. If the solar reversals are 'mild' reversals, and our own magnetic field is at full strength, then we could sustain our polarity. If the sun did undergo a strong and turbulent reversal, and our heliosphere was weak, then it would possibly influence our alignment. Our own magnetic reversals tend to work in cycles of approximately 12,000 year cycles (depending on which stream of academics you paddle in ), and occassionally we only have magnetic excursions instead of reversals. Excursions are a wandering of magnetic north over an undetermined distance, and then realigns itself to 'proper magnetic north'.
When the sun flips and we dont (North/south vs South/North), then we get a magnetic flux between us and the sun that resembles the number 0. When our magnetic north is the same as the sun the field resembles the number 8 turned sideways.
The real drivers of climate are the Sun’s insolation (light and heat), its magnetic flux, and the relative position and orientation of the Earth to the Sun.The variations in the Sun’s magnetic flux controls the amount of cosmic rays impinging on the atmosphere. Cosmic rays produce ionizations and the ions form nuclei for cloud formation. Cloud cover has a great effect on global temperature, but this area is still poorly understood and not addressed in climate models
Russian Scientist — New Little Ice Age Near
By Robert On November 13, 2012
Dr Habibullo Abdussamatov, head of space research at Pulkovo Astronomical Observatory in St. Petersburg, Russia, is suggesting the next Grand Minimum in this paper: Bicentennial Decrease of the Total Solar Irradiance Leads to Unbalanced Thermal Budget of the Earth.
From the early 90s, Dr Abdussamatov has observed bicentennial decrease in both the TSI and the portion of its energy absorbed by the Earth, which, he says, will result in a temperature drop in approximately 2014.
Then, due to the ensuing increase of albedo and decrease in greenhouse gases, the absorbed portion of solar energy and the influence of the greenhouse effect will additionally decline.
He expects the onset of a deep bicentennial minimum of TSI in 2042±11, and the beginning of a Little Ice Age – the 19th Little Ice Age in the past 7500 years – in 2055±11.
