Although not fully understood yet ,the tilt of the earth and variation in the orbital plane with occasional orbital eccentricty cause climate change ,a fact known for at least the last fifty years,in which the magnetic fields also play a part. The brilliant scientist Manikovitch published a treatise in 1978 which was promptly ignored by his fellow scientists as probably they thought it was unimportant!
