I take it your not interested in orbital mechanics? There are 11 known cycles of which solar min/max is just 1. Other cycles include the shape of the earth’s orbit from circular to elliptical 11,000 year cycle, position of the sun in our arm of the Milky Way - 3 million year cycle. Precession of the Earth’s & Suns orbits - multiple variable cycles. That’s four with seven others remaining. What we’re talking about is solar and galactic radiation. The earth receives more solar and galactic radiated energy in one week that all of the energy man has used in the history of the earth. To suppose that mankind effects the climate even in a miniscule way is ludicrous. The assumption that gases in the atmosphere effect the weather is equally ludicrous. The culprit/benefactor is water vapour. Water vapour is what carries the heat. Vulcanism is also a little understood factor. Earth’s early climate changes were certainly affected in the very short term by vulcanic activity. Considering that glacial periods can last a million or more years and interglacial period are very short, that is where our attention should be focused. We’re are on the verge of decent into a long glacial period which may or may not be preceded by several ‘mini’ ice ages.
